Publications of the United States National Museum The scholarly and scientific publications of the United States National Museum include two series, Proceedings of the United States National Museum and United States National Museum Bulletin. In these series, the Museum publishes original articles and monographs dealing with the collections and work of its constituent museums—the Museum of Natural History and the Museum of History and ‘Technology—setting forth newly acquired facts in the fields of anthropology, biology, history, geology, and technology. Copies of each publication are distributed to libraries, to cultural and scientific organiza- tions, and to specialists and others interested in the different subjects. The Proceedings, begun in 1878, are intended for the publication, in separate form, of shorter papers from the Museum of Natural History. ‘These are gathered in volumes, octavo in size, with the publication date of each paper recorded in the table of contents of the volume. In the Bulletin series, the first of which was issued in 1875, appear longer, separate publications consisting of monographs (occasionally in several parts) and volumes in which are collected works on related subjects. Bulletins are either octavo or quarto in size, depending on the needs of the presentation. Since 1902 papers relating to the botanical collections of the Museum of Natural History have been published in the Bulletin series under the heading Contributions from the United States National Herbarium, and since 1959, in Bulletins titled “Contributions from the Museum of History and Technology,’ have been gathered shorter papers relating to the collections and research of that Museum. This work forms number 281 of the Bulletin series. FRANK A. TAYLOR Director, United States National Museum For sale by the Superintendent of Documents, U.S. Government Printing Office Washington, D.C. 20402 - Price $3.25 PREFACE Hopefully the first part of this publication, a discussion of dyes used in America during the 18th and 19th centuries, will draw students and crafts- men into further exploration of this many-sided subject which encompasses chemistry, botany, textile technology, and fashion. The second part, devoted to dye recipes, is a revision of the United States Department of Agriculture Miscellaneous Publication No. 230 ‘“‘Home Dyeing with Natural Dyes” by Margaret S. Furry and Bess M. Viemont. Although this publication was issued in December 1935, the information gained through the research remains pertinent and useful for today’s dyers. I wish to express my appreciation to Mr. Dieter C. Wasshausen of the Department of Botany, Smithsonian Institution, for assigning contemporary equivalents to all the early botanical sources of dyes mentioned.

From (Swartz, 1841, p. 36) HISTORICAL BACKGROUND Coloring is one of the most delightful arts, also a most responsible branch of manu- facture; and a good dyer makes a manufacturer wealthy, happy, and renowned, while a poor one brings ruin, bankruptcy, and misery; and not considering the fineness of the cloth or the faultless weaver, the color sells the goods. This statement, by a dyer who started working a hundred years ago (Haserick, 1869, p. 2), echoes a sentiment well understood by today’s colorists. It is difficult to imagine that before the mid-19th century professional dyers of fine silks and woolens had to rely on such homely substances as dried insects, roots and leaves of plants, and chamber lye for carrying on their work. The accidental discovery in 1856 by William Henry Perkin of a lavender dye artificially produced from a constituent of coal tar marked the first step in the decline of the use of natural dyestuffs and the rise of the synthetic dye industry throughout the world. Today natural dyestuffs have practically no economic importance. A fairly simple explanation for this almost complete rejection of materials that had played such an important part in commercial and industrial life during centuries past is that the quality and effectiveness of natural dye- stuffs depended upon a great many factors. The dyestuffs were difficult to store, and much time was spent in extracting color from these raw materials and imparting it in cloth. Dyes made in the laboratory do not depend upon growing seasons and do not have to be ground or chipped before they are ready for use. Many, such as indigo, are chemically identical to natural dyes; since they are manufactured pure, their colors are unaffected by the impurities that dim dyes of vegetable origin. Before synthetic indigo was introduced to the market in 1897 natural indigo had been considered of excellent quality if it yielded 48 percent of its weight in pure coloring matter. Today natural dyes are used in limited quantities by craftsmen in various partso f the world. Although difficult to obtain commercially, dyes are readily obtained from plant materials gathered in gardens, woods, and along roadsides. Craftsmen are becoming increasingly enthusiastic about this out-dated and time-consuming process for one of the reasons that manufacturers rejected it: difficulty of standardization. Natural dyestuffs produce offbeat, one-of-a-kind colors. No two dye lots are identical, each having subtle differences due to impurities peculiar to the particular plant 3 material used. Thus the very characteristics of natural dyes that often made them the despair of earlier dyers appeal to today’s craftsmen searching for the unique. Textile Dyeing Before the Discovery of America The first western dyers were probably the Swiss Lake Dwellers who lived about 2000 B.C.; in the East a Chinese chronology dated a thousand years earlier mentioned dye workshops, so the craft must have originated in China some time before 3000 B.C. Among other ancient peoples, the Egyptians of the Middle Kingdom not only dyed textiles but also under- stood the use of mordants (metallic salts with an affinity for both fibers and dyestuffs that improved the colorfastness of certain dyes). The Phoeni- cian dye industry, begun in the 15th century B.C., was renowned for its purples obtained from a species of shellfish processed in the city of Tyre until 638 A.D. when the Tyrian industry was destroyed by conquering armies. India, the country whose dyeing practices have exercised the greatest influence on European dyers from the 16th century, appears to have had a dye industry long before its transactions were recorded in writing, perhaps extending to the period of the Indus Valley civilization ca. 2500 B.C. Marco Polo described in detail its indigo manufacture during the 13th century A.D., about three hundred years before the Portugese in- troduced it to Europe. European dye techniques improved slowly before the 18th century— mainly through trial-and-error. During the second quarter of the 18th century a number of French chemists began to organize contemporary information on textile dyeing and through experimentation gradually developed an understanding of the chemical and physical mechanisms of dyeing. Application of these theories gave impetus to the French textile industry and encouraged dyers in other parts of Europe and the United States to apply scientific methods to their own work. The American Indian contributed comparatively little to the European settlers’ knowledge of textile dyes. Scattered references suggest that while the Indians obtained some coloring materials from their natural surround- ings which abounded in dye plants, the colonists generally depended on traditional methods and imported dyes whenever they could be obtained. Textile Dyeing Among European Colonists and Their Descendants No matter how seriously the subject of textile dyeing is discussed, one must inevitably acknowledge that the basis of the whole business is a 4 luseemde nts imp arj nocde dures mipna gi n d(1r7yEn., 7 en2ic)ny.gc lopédie oFwdrsaifryh o ero nwkc shh op interyi na r ITykha er n. isin g |“1I.Gu—UDRyEe singularly powerful but frivolous one, fashion, and that the center of the fashion world around 1800 was Europe. Thus Americans still looked to Europe for the latest fashion colors and, to a great extent, for dye ma- terials that produced them. Elijah Bemiss was keenly aware of this situation when he remarked: Europeans apprised of our increasing manufacturies, attempt to baffle our attempts by imposing on us mixed cloth as fashionable; they are sensible that the younger look to the older nations for the patterns of their garments, and for fashionable colours of their cloths; for this reason the Europeans frequently change or mix their colours to retain our adherence to their markets (1815, p. 262). Almost all the professional dyers who practiced their trade in America until the mid-19th century either were trained in Europe or employed by men who had such a background. Evidence of this can be found by studying dye manuals printed in America during this period. It was natural that dyers would prefer ingredients they had learned to use in Europe. Thus mu i SS MAH SSS 1 3 uy Ficure 2.—The earliest known illustration of the interior of an American dye house (Hazen, 1836). Left: A worker lifting a dye bucket from a vat heated by a furnace that encases the vat. Right: Workers bent over various vats. The cloths draped on overhead beams indicate that finished cloth was being piece-dyed here. 6 it is not surprising that a table of “‘Goods and Produce imported into the several Provinces in North America. . . .” in 1770 included 70 tons of imported dyewoods (Sheffield, 1784, table 4), even though these were expensive and their availability fluctuated. Imported dyes were generally superior to the domestic product due to lack of knowledgeable American technicians. Even when high quality raw materials were produced here lack of experience in preparing them reduced their market value. Only indigo succeeded for a span of about thirty years, boosted by a sixpence-per-pound bounty payment which was finally cut off at the start of the Revolutionary War. In producing good quality indigo it was important to pick the leaves and process them at their peak of maturity—just before the plant flowered. Some South Carolina planters, unable to ferment the leaves all at once after they matured, allowed them to remain in the fields two to three weeks after they ripened. This indigo had to be marketed as a second-rate product, since it could not yield the maximum quantity of dye. Planters in Bengal, India, avoided such a situation by simply staggering plantings. Thus indigo, successfully marketed before the Revolutionary War, could not compete in price with the East Indian product after the conflict. When southern planters learned that rice and cotton were more profitable, these superseded indigo as their cash crops. Certainly many attempts had been made to exploit the natural resources of the colonies since the first colonists’ arrival. English naturalists recorded in illustrated volumes their observations on the flora and fauna of the new land and their possible uses, while colonial governors sent specimens to England for study. These efforts showed the great interest in natural curiosities typical of the 17th and 18th centuries, and also the desire of the English to find new sources of cheap raw materials. All efforts toward using dye drugs to this latter end eventually failed. Then because other crops proved more profitable, dye plants were not cultivated in the United States on a commercial scale during the 19th century. Before the Revolutionary War high import duties added to the prices of dyes. The post-war situation found dyers stil. suffering the hardships of high tariffs imposed on dyes imported from European countries and their colonies. Asa Ellis clearly expressed the Americans’ problems and their possible solutions in these remarks: For a great proportion of the ingredients employed in dyes, we depend on Europe to furnish . . . As we attempt an independence of their markets, they increase their duties on dyestuffs which we import. Not one cask, of Cochineal, can we obtain from our sister continent, South-America; from thence it must pop through the hands of Spain and England. From England we receive it, at an extravagant price . . . Foreign nations receive a large revenue from this country, for the dyestuffs we import. Does it 7 become an independent nation, to be thus dependent on others, for articles, which, perhaps, may abound in our own country? Or shall we, without enquiry conclude that nature has denied us these articles; being partial in the distribution of her favours? . If our government should consider it worthy of their attention, to encourage some able chemist to explore the qualities of our fossils, woods, barks, shrubs, plants, roots, weeds and minerals, perhaps, the advantages, our rising nation might derive, would soon indemnify us for the extra expense (1798, p. 137-139). The following list of dye prices from an 1831 dye manual shows the price relationship of the six principal dyestuffs; the list also indicates that cochineal maintained its luxury price long after the wars with Britain: quercitron, per lb. $ .06 fustic Scones . 06 logwood et 06 madder eeoes . 1834 indigo S688 PAS, cochineal _ per oz. .31 a 37% (Lynde, p. 8). Lack of funds for luxury dyes like cochineal, plus distance to cities where such items were obtainable, forced many rural inhabitants to explore their surroundings for dyes for the wool and linen yarns of their own manufacture. Unfortunately the full extent of home dyeing and its importance in the overall view of colonial American textile manufacture may never be assessed accurately because written records on the subject are scanty. One exception is an excerpt from An examination of Lord Sheffield’s observations on the commerce of the United States, on the state of American dyeing, pub- lished in 1791: The implements hitherto used in household manufactures, have been of the most ancient kinds. The art of dyeing has been advanced in families little further than what was communicated by a recipe as brief as those in a book of culinary instructions; the colour- ing ingredients have generally been such as nature handed to the thrifty housewife. The operations, from the raw to the manufactured state, have often been the simplest that can be conceived. Under circumstances like these, it will not be too sanguine to expect the dissemination of useful instruction in the practice of dyeing, in the nature of colours, and concerning other parts of the business . . . ({Coxe], 1791, p. 120). The sense of nationalism and desire for self-sufficiency on a national scale boosted American manufactures after the Revolution. Unfortunately the voices of influential individuals, such as Thomas Jefferson and Dolley Madison, raised in favor of home-grown dyestuffs, could not persuade farmers to raise madder, indigo, woad, or weld crops on a commercial scale. During this same period, however, the dyer’s profession here advanced with sound chemical practice, gradually replacing former trial-and-error methods. We must depend mainly on personal papers, regional and family tradi- tions, and books of miscellaneous household recipes for home dyeing infor- 8 mation. Among the latter were volumes such as Mackenzie’s five thousand re- ceipts in all the useful and domestic arts, assembled by the Englishman Colin Mackenzie and adapted for use in this country by “‘“an American Physician.” This particular book went through numerous printings throughout the 19th century. One edition, printed in 1831 in Philadelphia and Pittsburgh, provided many good ideas on the subject of coloring textiles. It seems strange that such a volume, meant for the use of novices, often left so much to the imagination and judgment of the dyer. For example, in explaining the use of alum as a mordant the author states: Alum, to make a mordant, is dissolved in water, and very frequently, a quantity of tartrate of potass is dissolved with it. Into this solution WOOLLEN cloth is put, and kept in it till it has absorbed as much alumine as is necessary. It is then taken out, and for the most part washed and dried. It is now a good deal heavier than it was before, owing to the alum which has combined with it (p. 81). Important sources of information on raw materials used in 18th and 19th century American dye houses are the manuals written by dyers and printed in the United States between 1797 and 1869. Very few of these publica- tions are the original works of Americans, since many were printed first in England, while others are merely collections of recipes assembled from earlier French, English, and German books. Frequently authors lifted whole sections of earlier works without crediting the original sources. When such volumes were printed in the United States, however, they were sometimes adapted for American use, with plants found in America added to the others. Even when no attempt was made to adapt recipes, the fact that these books were printed and sold here suggests that the foreign methods and dyes described were utilized by American dryers and clothiers. Other sources, more difficult to ferret out, are dyers’ and apothecaries’ newspaper advertisements and patents. Dated apothecary advertisements often revealed partial stocks of these shops, which usually included some dye drugs and chemicals. Patents related to dyeing and dyestuff processing are virtually untapped sources of information, particularly interesting because they show the relationship between dyers and other craftsmen of the period. Dyeing After 1850 Perkin’s discovery in 1856 of a lavender dye made from aniline, a coal-tar product, marked the beginning of the end of the natural dyestuff era. It created considerable excitement in England and soon became popular in France, where the new color was known as mauve. “‘Queen Victoria wore a mauve dress at the Great Exhibition of 1862, penny postage stamps were 9 Figure 3.—Commercial piece-dyeing in England (Tomlinson, 1854).

Although news of the new dye reached the United States soon after its appearance, a number of years passed before it was in general use—partly due to the political upheavals that were taking place in America during that period. For decades after aniline dyeing became standard procedure, the old natural dyes continued to be used side by side with the latest manufactured. dyestuffs. But by the end of the 19th century all but a few natural dyes such as logwood, indigo, catechu, and cochineal had been replaced by the more dependable manufactured dyes. At that time Ameri- can professional dyers depended almost entirely on Germany for supplies. World War I cut off supplies of dyestuffs, causing a “dye famine’’ that jolted American chemical manufacturers into the business of large-scale dye manufacture. During the war there had been a temporary upsurge in demands for natural dyes. As soon as American manufacturers could supply the textile industries with a wide range of colors, however, natural dyes became obsolete. Only in mountainous and rural areas of the southeastern quarter of the country, traditional methods of weaving and dyeing survived among home dyers unaware of developments in large-scale chemical dyeing. These country dyers, working far from the mainstream of American life, did not follow the trends toward standardization of dyes and dyeing pro- cedures generally accepted in the northern industrial areas. ‘They are unique in this respect and preserved traditions of home dyeing with natural ma- terials longer than any other group of dyers in the United States. During the first quarter of the 20th century a revival of interest in arts and crafts led to experimentation with old methods of spinning, weaving, and dyeing. This movement, plus efforts to encourage the continuation of southern mountain folk crafts, inspired textile craftsmen throughout the country to explore the field of natural dyes once more. During the same time the Navajo Indians almost entirely ceased working with the generally poor quality commercial dyes they had used since the late 19th century, replacing them with natural dyes. Today the Indians are once again turning to chemical dyes in which improved color range and fastness and ease of application permit users to color yarns more quickly and efficiently than heretofore. Many contemporary textile craftsmen, working professionally or as hobbyists, however, turn to natural dyes for color ideas. Although fine, dependable commercial dyes are on the market, devotees of natural coloring materials derive a nostalgic pleasure from handling vegetable materials and extracting uniquely “impure” colors from them. It is this latter group who would find that experimentation with untried plants might turn up unexpectedly interesting results. 12 Tak Dyes Ors There are, no doubt, a great number of dying drugs in this country, which, if known, might become valuable. It is much to be regretted, that some institution does not exist in this country to test and bring to notice its native colouring matters. In the hands of a practical and theoretical dyer, many valuable discoveries might be made of new dyes now lying dormant. Many of them might be used to advantage by the dyers of this country, and also become objects of some magnitude, as exports. In spite of this notion, expressed by William Partridge in 1847 (pp. 37-38) and subscribed to by many others since his time, we know that the American dye industry never could rely on home-grown raw materials. The most important and most frequently used dyes of the United States in the 18th and 19th centuries were indigo for blue, madder and cochineal for red, and fustic and quercitron for yellow. Logwood was the most commonly used black dyeing ingredient, and sumach, though not strictly a dye, so often was used in neutrals and blacks that it deserves a special mention along with the other six coloring materials. Of these only quercitron and sumach were native to the United States. To complete the picture of dyes used in this country during the 18th and 19th centuries and to suggest plants for further experimentation, appendixes B, C, and D have been included. Appendix B is a list of dyes occasionally mentioned in dyers’ publications printed in America between 1797 and 1869; Appendix C provides a list of South Carolina dye plants compiled during the first decade of the 19th century; and Appendix D is a list of dye plants which Thomas Cooper translated and borrowed from the work of D’Ambourney and included in his 1815 dye manual. Most of the dyestuffs which were regarded as basic stock in dye houses are discussed in detail below. The remainder are native materials less frequently mentioned in dye manuals but very likely used by home dyers because of their availability. BLuE DyEs *TNDIGO 1 (Indigofera tinctoria) also known as anil (Fr.) WILD INDIGO (Bapftisia tinctoria, formerly known as Sophora tinctoria) Indigo, the dyestuff most widely used in America during the 18th and 19th centuries, is not a native of this country. It is a blue dye derived from the leaves of a leguminous plant which grew in India and Egypt long before the Christian era and later used by the Romans in making an ink they called indicum. In the 16th century it was brought to Europe from India by Portuguese, Dutch, and English traders. 1 Recipes for dyes marked with an asterisk (*) are given in Section 2. 13 eB bY FESS) 16. =.B OiV>E hu 2 LD Goth es d.e tAnil a Ficure 4.—Indigo plant (Pomet, 1694). The earliest known attempt to grow indigo in America is revealed in a tract dated 1649 (Force, 1838, p. 4).2 From it we learn that indigo was planted with the notion that it would eventually prove ten times more 2 This excerpt from an anonymous letter included in Peter Force’s collection of early documents appears in a section entitled “A Perfect Description of Virginia: Being a full and true Relation of the present State of the Plantation, their Health, Peace, and Plenty . . .. certified'by diverse meni). 2 2 14 profitable than tobacco, and that the planters hoped to grow enough indigo to take over India’s profitable indigo trade. Since no more is heard of indigo cultivation in the colonies until about ninety years later, one assumes that the project failed. This indigo may have been the plant sometimes called wild indigo or yellow wild indigo (Baptisia tinctoria) mentioned by John Clayton, who supplied information for an 18th-century book on the flora of Virginia (Gronovius, 1762, p. 64). Dutch settlers also attempted to grow wild indigo in New York City and Albany as early as 1650 (Bishop, 1866, vol. 1, p. 348). Other scattered references to wild indigo appeared throughout the colonial period and in the later 19th century. One informs us that as late as 1873 some South Carolina planters still cultivated it, contending that in spite of indigo’s low price—75 cents per pound—it was still more profitable than cotton (‘‘Baptisia Tinctoria,”’ 1895, p. 81). Introduction of a species of Indigofera to South Carolina in 1739 and its subsequent commercial success must be credited mainly to the intelligent and persistent efforts of Eliza Lucas Pinckney. Her father, Governor of Antigua at the time, sent her seeds of various plants that might be suited to growing conditions in Carolina. After many trials she managed to produce enough indigo in 1747 to make up a shipment for England. It met with approval in England and remained the staple crop of the colony from the late 1740s until the war, reaching its peak in 1773, when 1,107,660 pounds were exported to England (Sheffield, 1784, table 1). During the war this crop was neglected in favor of rice; after the conflict it could no longer compete with the cheaper but better quality East Indian variety. Thus toward the turn of the 18th century cotton took over from indigo as Carolina’s important crop. Georgia and Louisiana cultivated some indigo but never succeeded in making a large-scale commercial success of it. The French had introduced indigo to Louisiana in 1718, and 10 years later its export began. With the help of French bounties, indigo production and exportation continued until later in the century when it was learned that cotton could be produced more profitably (Bishop, 1866, vol. 1, p. 348). Natural indigo was used throughout the 19th century, for it was not synthesized until the 1870s, and more than 20 years passed before methods were devised for producing it in quantities and at prices suitable for mar- keting. Synthetic indigo has replaced that of natural origin to such an extent that natural indigo is now practically impossible to obtain in this country. Indigotin, the main constituent of indigo, is prepared from the leaves of various species of Indigofera. Only about four ounces of indigotin are extracted from 100 pounds of plant material, according to a 20th century IS ‘ \ iY NSYS 16 Ny vatba bro?q v 727] *(F69T “yowog) Arp 0} [eliazew ap pozezdioaid ay} Suds pue ‘sy]e]s OSIpul Suryeos oy} Sunepse Gea pol[y-ioyeM v Ul syyes oy Suloejd Quejd oy2 SuNqno apnyour sdayg *ArnqUs YIZ] a2e] ey Suunp eipuy ut uoneiedsid ostpur jo uonezeidiojzur sueurysue1 e—Sutssooo1d o3ipuy—¢ aANoIy NE SS Yi] Reap source. Preparation for market requires many steps: First the plants are cut just as they mature, then steeped and allowed to ferment; next the solution containing indigotin is drawn off and the plants are disposed of; the indigotin solution is then subjected to another series of steps. The solution is beaten with paddles to incorporate air into it and to promote oxidation. When oxidation is complete, the indigo material is allowed to settle, the liquid is drawn off, and the mass of indigo, pressed, cut, and dried, is ready for market. Early in the 19th century, indigo was often sold in the form of dark blue cubes or cakes called “junks.” The quality of these ‘“‘junks’ was a matter of great concern to the professional dyer, for indigo was an expensive dye. If, as one dyer stated, 6% pounds of indigo would dye 100 pounds of cloth a full deep blue, the cost of indigo alone per pound of cloth dyed would be more than 14¢, based on the 1831 price of $2.25 per pound (Lynde, p. 8). The cost of indigo and other indigo dye ingredients such as potash, bran, and madder, plus labor costs, added up to a very costly dye operation. Opinions differed greatly on which country exported the best grade of indigo. Some dyers considered Bengal (India) indigo the best, claiming that it would color at least 10 percent more cloth than the best Spanish Flote indigo, imported from the Spanish dominions in central America. The criteria by which the 19th-century dyer judged the quality of indigo included: light weight in relation to bulk, smoothness in the fracture, and a bright violet, purple, or bronze hue. There was general agreement that the price paid for the indigo should be in proportion to its yield. ‘Thus sometimes buying low-priced indigo with moderate yield could be more profitable than purchasing the highest priced article with proportionately lower yield. Since the indigo vat is described in detail in the Dye Recipe section it is only necessary to make some general remarks about indigo dyeing practices in America. One learns from early dye manuals that many kinds of blue vats were worked. The main ingredient in all of these was either woad, indigo, or a combination of both. Dyers’ opinions differed on the relative merits of woad and indigo; however, it is now known that although the dyeing ingredient indigotin is common to both dyes, it is present in indigo in much greater quantity. Indigo is insoluble in water before dyeing, but it is made soluble in the blue vat. Dipping textile material in the dye solution deposits dye in the fibers. When the textile is removed from the dye vat, the air oxidizes the indigo, returning it to its original insoluble form. Several combinations of ingredients will help to put indigo into solution. These account for the variety of instructions for making up blue vats that 17 one encounters in 19th century dyers’ books. The main purpose of these ingredients was to combine them with indigo to reduce it and make it soluble in alkali solutions; in this dissolved state indigo could be absorbed by textile material. Bran and madder, by inducing fermentation, act as reducing agents. Other chemical compounds (such as copperas) which also act as reducing agents were frequently used. Indigo, in its reduced state, then is dissolved in an alkali solution—usually made up of lime, potash, or soda in water. A typical and comparatively uncomplicated vat that Thomas Cooper said was used by wool dyers of Pennsylvania and American back-country dyers (1815, p. 45) is basically similar to the ‘‘Blue-Pot’’ recipe given in the Dye Recipe section. Another dyer of the same period commented that urine used as a fermentation-inducing ingredient in indigo dyeing had been used with great success. Each individual dyer’s procedures were adapted to the amount of cloth dyed, frequency of dyeing, and the available ingredients. Thus though the blue vat was often worked under primitive conditions, 18th and 19th century professionals and home dyers alike considered the complicated indigo-dyeing process as the basic method of coloring textiles. Other Blue Dyes Although indigo was by far the most important dyestuff used throughout 18th- and 19th-century America, a few other blue dyestuffs were employed by professional clothiers and dyers. Among these were woad, chemic, and Prussian blue. WOAD (Isatis tinctoria) Also known as pastel (Fr.); der (Farber) Waid (Ger.) Woad was well known long before the Dutch introduced East Indian indigo into Europe late in the 16th century. During the 17th century, indigo’s value became more and more recognized in spite of determined efforts by the guilds of the woad processors to limit its use. Woad was probably the first blue dyestuff used in America, carried from their mother country by the earliest colonizers. By 1700, however, indigo could be obtained from the West Indies, and from that time woad’s importance diminished as indigo became more and more widely used. The woad vat was basically similar to the indigo vat, requiring care in controlling the fermentation process by which the coloring agent was reduced to its soluble form. According to many 19th-century American dyers, great skill was required to develop the correct degree of fermentation in the woad vat due to great quality differences in the raw material. Often the experienced woad dyer’s most valuable asset was his sensitive nose, 18 with which he could detect changes in the fermenting activity, the changes in turn signaling when more lime or bran should be added or the vat stirred. Perhaps early dyers were not aware that indigo and woad contained a common dye principle, indigotin, and that indigotin was present in greater concentration in indigo; however, they gradually realized that woad was definitely the less potent of the two substances. Long after dyers discovered the true value of indigo it was still being used in combination with woad, because it was supposed to promote fermentation and to ‘‘render the colour brighter.”” Regarding the latter, some dyers felt that only with the addition of woad could certain fine blue tones be produced. This notion may have been true, or it may have simply indicated the dyers’ lack of skill in working indigo vats to produce these hues. Very little woad was grown in the United States. Some was grown in Britain, but most of the woad used here was imported from France and Holland. William Partridge in 1847 remarked that an inferior quality of woad had been grown and marketed by a number of farmers located in the Hartford, Connecticut, area. He felt that the inferior quality was the result of poor processing. Homegrown woad, also mentioned by other dyers of that period, was probably raised on a small scale in various parts of Northeastern United States, since growing conditions were quite suitable for its cultivation. Processing was a far greater problem than growing, for even before 1t could be used woad required long, complicated fermen- tation and drying procedures. It was sold in the form of 150- to 200-pound bails and also in balls that resembled clods of dried earth interlaced with plant fibers. Although its use continued throughout the 19th century, its importance diminished gradually until the end of the century when it was practically obsolete. Woad is last mentioned as a dye ingredient in early 20th-century English dye literature; by that time its use was certainly very limited. CHEMIC (a popular name for indigo sulfate) or Saxon blue Chemic, frequently mentioned by 19th-century dyers, is a product of the treatment of powdered indigo with concentrated sulfuric acid. Its properties were totally different from those of indigo, for chemic had poor fastness to light and washing, contrasted to the indigo vat dye’s excellent colorfastness. It was applied to some silks and coarse wools and even cotton because of its relatively simple application (mordanting and immersion of cloth in dye solution) and characteristic, though short-lived, blue coloring. According to one story chemic was discovered by a certain Mr. Seidelman who lived in Altenburg, Saxony, during the mid-18th century. He com- bined sulfuric acid with powdered indigo, which made a black paste. This 19 black paste was then set aside in the dye house where he was employed, and after a while, thinking it was useless, the dyer threw the compound out the window onto the snow. As the snow melted Mr. Seidelman “saw... the beautiful blue veins of the dissolved indigo. He at once took part of it in a tumbler of hot water, added some alum and dipped some wool yarn into it; the result was a new color’ (Haserick, 1869, p. 17). Supposedly he later sold his secret in England for $6,000. Apparently this rather inferior dye was used by professional dyers on coarse goods throughout the 19th century; with improved methods of application, its use continued until the early 20th century. PRUSSIAN BLUE Also known as bleu de Prusse (Fr.); das Berlinerblau (Ger.) One of the earliest chemical dyes used in America, Prussian blue is made by combining prussiate of potash with an iron salt in which the prussiate acts as a dye and the iron salt as a mordant. They combine to form a white solution that turns blue when oxidized. Its discovery is credited to a German chemist of the first decade of the 18th century, but its practical application was delayed for about a hundred years until a method of fixing it on fabrics was developed. The first use of Prussian blue in this country appears to have been in 1832, when F. Tassard of Philadelphia dyed broadcloth ‘‘Lafayette” blue. Specimens of this cloth, made in Dedham, Massachusetts, were exhibited at the Fair in the American Institute in New York in 1833 (Bishop, 1866, vol. 2, paol2): Prussian blue-dyed cotton is extremely fast to light; however, the same coloring agent darkens on wool and decomposes in boiling soap solutions. In applying Prussian blue to silk, only the prussiate of potash needs to be applied if the silk has been weighted previously with iron salts. Weight- ing eliminates the need for an extra mordanting step, and thus simplifies the dyeing procedure. Prussian blue was used until the early 20th century when improved means of achieving the same color made it obsolete. Rep DyEs *MADDER (R ubia tinctorum) Also known as common madder; garance (Fr.); der Krapp (Ger.) It is well known that Madder is so essential to dyers and callico-printers, that neither business can be carried on without it. The consumption of it is so great in England, that, upon a moderate computation, more than 180,000 sterling, is annually paid for what is imported from Holland, exclusive of their supplies from other parts; and as in a little time, manufacturers of these kinds, must of necessity, progress in America, the sooner some attention is paid to this article, the better. 20 This opinion was expressed by Bernard McMahon of Philadelphia, author of one of the most important American garden books of the early 19th century (1806, p. 322).° Doubtless many of McMahon’s contemporaries agreed with him on the importance of madder. It was a staple red wool, silk, and cotton dye by the 18th century, although it had probably been brought to America a century earlier by immigrating colonists. Madder dye was obtained from the roots of Rubia tinctorum until the last quarter of the 19th century when alizarin, its main constituent, was synthesized. The perennial madder, a native of Asia Minor, was cultivated in Italy, then France and Holland. Most madder imported to America came from the latter two countries. It seems strange that it was never cultivated to any great extent in America though growing conditions were considered quite suitable. In 1785, the Society for the Promotion of Agriculture in South Carolina offered a premium for growing madder. Many prominent citizens, among them Thomas Jefferson and Dolley Madison, strongly urged farmers to raise this useful plant. Evidently Jefferson was personally interested in madder cultivation, for an 1811 entry in his garden book reveals that he imported madder seeds from France and planted them in the southeast corner of his garden. This madder, Galium mollugo, was known as wild madder, and although its roots also contain red dye, it is a member of the lady’s bedstraw family and not the true madder, Rubia tinctorum. Jefferson, in replying to a Boston gentleman’s query about madder, recalled that it had been cultivated in Virginia for household use since before the Revolution (Jefferson, 1944, p- 452). The American Philosophical Society in 1802 offered a $150 premium for the “‘best experimental essay on the native red dies of the United States.” Mrs. Madison was to have made a report to the society on speci- mens dyed with madder raised under her direction; however, this paper never appeared in the society’s transactions. Thomas Cooper, in his account of madder cultivation in the settlement of Harmony, about 20 miles from Pittsburgh, Pennsylvania, reported that 8 or 10 acres of madder were planted annually for local consumption. Homegrown madder was very simply prepared. It took 3 years for the roots to reach their peak yield. Then, according to Jefferson, the fresh root was beaten into a paste 12 hours after it was washed. He claimed that fresh madder was twice as potent as the dried root. Commercial madder 3 This entry does not appear in the 1857 edition. Thomas Jefferson’s letter to William Coolidge on the cultivation of madder refers to the 1806 edition (see Jefferson, 1944, p. AD2)): 21 PONS Sous ‘ SN Figure 6.—Madder plant. An illustration based on one in Gerard’s Herbal of 1597 (Pomet, 1694). 22 imported from Holland went through many more complicated preparatory steps. First it was oven-dried then pounded into powder. The husks removed in this first pounding were sifted out and sold at a low price. The second pounding resulted in separating out one-third of the remaining roots and, after sifting, this material was sold as an intermediate quality. The final pounding left only the “‘interior, pure and bright part of the roots” and made up the first quality “‘Kor Kraps”’ or crop madder. Packed in casks, madder’s potency would increase with aging for | to 2 years. During this aging period and during shipping, it tended to pick up moisture that could, in excess, deteriorate the madder. Besides overaging, buyers had to contend with the possibility of adulteration with brick dust, sand, mahogany wood, almond shells, and many other mineral and vegetable substances. Mineral sub- stances were generally less harmful because they would simply reduce the quantity of dye as they settled to the bottom of the vat; however, vegetable substances could sadden bright red hues. Madder dyeing of cotton, called Turkey red dyeing, originated in India, from there it was transmitted to other parts of the East (including Turkey, from which the process derived its name) and eventually was carried to Europe by the French. Turkey or Adrianople red became one of the most sought-after colors of the 19th century. In 1840 the Merrimac and Hamilton Mills in Lowell, Massachusetts, alone produced more than a quarter- million yards of cotton fabrics dyed or printed in madder colors “‘of a price and quality that rivalled the foreign” (Bishop, 1866, vol. 2, p. 421). The whole process was, according to one dyer, the most complicated application of mordant in the whole art of dyeing, requiring, in addition to madder, an oil, galls, alum, dung and—in one recipe—the intestinal liquor of a ruminating animal and the blood of oxen or sheep. John Rauch, whose dyebook gives complete directions for Turkey red dyeing, believed that the dyer of such yarn had to have his whole dye house geared to that purpose only. He felt it was necessary to have 4,500 or 5,000 pounds of yarn on hand, so that with the assistance of 8 or 10 helpers the dyer could finish 100 pounds per day (1815, p. 34). Rauch stated that it took 16 actual working days with one drying day allowed after each day’s work. A total of 40 to 50 days were required to complete the process. Basically cotton was prepared by soaking in soda, after which the cloth went through several days’ dippings in oil and sheep- dung solutions. Then it was dipped in soda and nitric acid, later in nut gall solution, and finally in alum solution. The first three-fourths of the process- ing mordanted and prepared the yarn. The actual dyeing in madder solution took only 3 hours. The remaining dips were in oil and soda solutions, concluding with a final alum, nitric acid, and water bath, rinse, and shade-drying. 2 The rich red color that resulted from this process was permanently fixed on the cotton yarn or cloth used in shawls, ginghams, and table coverings. *COCHINEAL (Dactylopius coccus, formerly known as Coccus cacti). Also known as cochenille (Fr.); die Cochenille (Ger. ) When the Spaniards entered Mexico in 1518 they found the natives dyeing with cochineal. This red dyestuff which the Spaniards mistook for tiny seeds was actually the dried bodies of the insect Dactylopius coccus. Soon the Spaniards shipped the dye back to Spain for export to various parts of Europe; later some cochineal was sent back across the ocean to the English colonies. Guatemala and Mexico were at first the two main sources of this dye, because the insects’ food Opuntia cochenillifera (sometimes called ‘“‘nopal”’ or “cactus opuntia”) grew in these countries. Opuntia also flourished in Georgia and South Carolina, thus there were great hopes that cochineal could also be produced in this country. In 1762 the Society of Arts offered a premium of £40 for the largest quantity im- ported from the colonies (Bishop, 1866, vol. 1, p. 350); however, there seems to be little further reference to its production here. Although it was high priced, after 1793 cochineal was considered a staple red dye along with the cheaper madder. Coarse woolen stuffs were dyed with madder or orchil, but fine cloth was almost exclusively dyed with cochineal, according to an 1831 source. Its coloring principle, carminic acid, produced beautiful crimsons, pinks, and scarlets on wool and silk when mordanted with tin or alum. Cochineal-producing insects, either wild or domesticated, yielded equally good color but the wild variety, yielding only one-fourth the amount of dye, was considered less desirable. As the insect matured, the wingless dye-yielding females were swept off the leaves to which they were attached and killed in hot water, then dried in the sun, or placed in a bag and stove-dried. The latter method yielded silver cochineal, so-called because of its silver ash-gray color. The other type was blacker and drier, and called “negra.” It takes 70,000 dried insects to produce one pound of cochineal and an acre planted with Opuntia yielded 250 to 300 pounds of the insects. Cochineal powder could be damaged by sea air and adulterated very easily, sometimes with “‘stones large as a fly.” Thus the wary buyer was warned to examine each sample carefully. The home dyer probably relied to a great extent on less expensive madder for her reds; however, if cochineal was purchased for home use it could be ground to a powder in a coffee mill or mortar. To dye woolen cloth, it was recommended that the cloth be finished— milled, napped, and sheared—before dyeing, since subsequent dressing would ‘‘tarnish the color.’’ Dyeing was comparatively simple, with tin 24: combined with tartar or an alum mordant used either in a separate bath or in the dyebath. The color could be blued by adding a little alkali— ammonia or sodium carbonate—to the dyebath. Sometimes professional dyers reduced costs by using part cochineal and part brazilwood or a yellow dye to stretch the cochineal. It was not always considered legitimate, but one dyer cautioned that it was better to comple- ment the cochineal with red dyewood than to overboil pure cochineal in attempting to extract the maximum amount of color. Cochineal was used even on a commercial scale until the turn of the 19th century when azo-scarlet dyes were introduced. None of the new synthetic dyes offered a perfect substitute, for as late as 1910 azo reds tended to bleed and stain neighboring colors. Because of more predictable quality, supply, and lower costs, azo reds eventually superseded natural cochineal red. Other Red Dyes Madder and cochineal were the most important red dyestuffs used in 18th- and 19th-century America. Next in importance were brazilwood and other red dyewoods. Although the colors they produced were fugitive these woods were known and used by most professional dyers, probably because they were cheap and readily available. The remainder of the reds were extracted from alkanet, annatto, lac, safflower, and local plants such as pokeberries. BRAXILWOOD (mainly Caesalpinia echinata) Also known as Pernambuco; Fernambouc; Santa Martha wood; Bois de Bresil (Fr.); Peach wood; Queen’s wood; redwood; das Rotholz (Ger.) The general term brazilwood refers to the wood of several different trees from which red dye was obtained. The common names listed usually denote the trees’ place of origin. The South American country, Brazil, received its name from the forests of red dyewood trees encountered by its discoverers when they landed about 1500. These trees were a Western Hemisphere species similar to the sappan (C. sappan) that grew in the East and had been known in Europe for over two-hundred years. ‘The Brazilian dyewood yielded a commercial quality of red dye that became a profitable article of trade throughout the American colonial period. By the beginning of the 19th century the supply of these trees had diminished considerably, and other available dyewoods of equal quality took their place. Caesalpinia sappan During the Middle Ages this brazilwood (C. sappan) was an important article of European commerce obtained from India, Malaya, and Ceylon. Eventually it became known in Europe and America as ‘‘sapan,”’ its Malay name, and was thus distinguished from other brazilwood. One 25 OS source incorrectly ascribes the origin of its name “‘sapan’”’ to a misinterpre- tation of ‘““Japan,”’ one of its countries of origin. Sapan, the most ancient source of brazilwood, remained in common use until some time after the middle of the 19th century. Haematoxylon brasiletto The third important source of brazilwood dyes was a shrub grown in Nicaragua, Colombia, and Venezuela (Haematoxylon brasiletto). Its export began about 1848, and its trade continued into the early 20th century when the First World War caused a brief revival of interest in natural dyes. The heartwood of this tree produced hues that ranged from reds to purples. Since the dye was fugitive, 1t was replaced by synthetic dyes soon after the war. Besides being called by the other common names for brazilwood, braziletto was also known as Nicaragua wood and hypernick. All brazilwoods that contained the basic dye ingredient brasilin were processed in the same manner. The reddish heartwood, shipped in log or stick form, was rasped or chipped before it could be used. It was treated like logwood: placed in a sack, immersed in a water bath until the dye was released, then the sack of chips removed before the wool, silk, or cotton material was entered. Different mordants such as nutgalls and alum with tartar produced a variety of red hues, values, and intensities, but none were as fast to light and washing as madder and cochineal. ‘These mordants could be applied to a textile before, during, or after dyeing. Brazilwood which gives textiles pink and claret hues was often used in calico printing and as a finishing dye in combination with other more stable but less brilliant hues. In this way it could be combined with log- wood to produce violet or brown or used to brighten madder scarlets; it was frequently one of the many ingredients used in black dyeing. CAMWOOD or BARWOOD (mainly Baphia nitida and varieties of Pterocarpus) and Sanders or Red saunders (Pterocarpus santalinus) Also known as das Kambholz (Ger.) Dye manuals of the 18th and 19th centuries distinguish between cam- wood, barwood, and sanders wood; however, all three can be discussed as a group since they all share a common dye principle, santalin, and the same botanical genus, Pterocarpus. Each has a different place of origin: camwood from the West Coast of Africa, barwood from Sierra Leone, and sanders (also spelled saunders, red sanders, santal, or sandal) from India, Ceylon and other parts of tropical Asia, and the Coromandel Coast (many 19th century works mention the latter as the source of sanders). These woods superficially resemble brazilwood in their red coloration (under certain conditions) and in imparting in textiles similar fugitive red hues. Their dyes were more lasting but much more time-consuming to 26 process because of the hardness and fine grain of the woods. The same basic dyeing technique, however, was still used for both dye groups. Camwood, barwood, and sanders were known but seldom used in America before the 19th century. The British had used barwood for dark red printed imitations of East Indian bandanas before 1814 (Bancroft, 1814, vol. 2, p. 251), yet while it was fairly durable on wool, the color was not permanent when applied to cotton. An American dyer of 1798 said that this reddish-brown dyestuff was imported in casks and ground fine like flour. The powder was far more convenient for the dyer than the stick form which had to be chipped very fine and required much boiling, yet it too had its drawbacks for, the same dyer continued, if the floury dye material was agitated a hot dust would arise to irritate the nose and throat glands. Another dyer 40 years later expressed the opinion that camwood injured the quality of (woolen) goods more than twice the value of the cost of dyeing. This harmful effect on wool is not mentioned in later scientific dye manuals. This raises the question of whether prolonged boiling or other processing could have been more responsible for injuries to cloth than were the dyestuff’s harmful properties. Most dye manuals emphasize the distinctive characteristics of the three woods grouped together here. The quality of the trees, care in packing and shipping, and variations in dyeing methods and mordants, however, probably influenced the color and degree of fastness obtained far more than variations between camwood, barwood, and sanders woods. These woods continued in use until the early 20th century when they were at last completely replaced by synthetic dyestuffs. The latest appli- cations of these woods were in combination with other dyes, producing compound shades such as browns, and in giving a bottom to woolens before indigo dyeing. ALKANET (Alkanna tinctoria or Anchusa tinctoria) Also known as alkanna, alkanea, orcanette, orcanéte (Fr.) Englishmen who landed along the southeastern coast of America probably found Alkanna tinctoria soon after they settled in their new homeland. Another variety of this plant was cultivated in England and France where it had been used as a dye for many years, thus it was undoubtedly quite familiar to many early dyers. In America the dye was probably much more important to the Indians than to European settlers who had access to more stable red-coloring agents such as madder. Hollberg in 1763 mentioned Anchusa virginiana as the source of puccoon, a yellow dye employed by the Indians for painting body designs. Since it is not found in the United States, it may have been mistaken for the European plant. Catesby and Ramsay gave the name puccoon to bloodroot (Sanguinaria canadensis) which yields a yellowish-red dye used by the Indians. 27 Home dyers undoubtedly used alkanet in areas where it was locally available. Red color is extracted from alkanet roots by immersing them in various solvents. The coloring material was placed in a water bath into which the textile material—usually wool or silk—was immersed. ‘This processing imparted a fugitive red color. An 1869 source also mentioned that limited amounts of cotton and thread were also alkanet-dyed a bluish lilac by using alum and iron mordants. ANNATTO (Bixa orellana) Also known as annotta; arnotta; roucou (Fr.); racourt; orlean; and otter Apparently annatto was commonly used during the 18th and 19th centuries, producing pink, reddish, and orange hues on cotton and silk, and yellow-orange colors in butter and cheese. The dye is derived from the orange-red outer covering of the seeds of a tropical shrub, Brxa orellana. Specific preparatory techniques differed; however, in general the seeds were soaked, fermented, macerated, and washed, then pressed into small cakes or sold as a paste. The shrub that bears this fruit thrives in tropical areas all over the world; however, annatto was imported to America mainly from South America. The knowledge that bixin, annatto’s dye principle, could be dissolved readily in alkali was applied in 1814 and later when an alkaline annatto solution was sold in London as “‘Scott’s Nankeen Dye.” All 19th century annatto-dyeing procedures employed potash and often used an alum mordant with a variety of recommendations for combining these ingredients. One early 20th century cotton-dyeing procedure required two steps: the cloth was first immersed in a warm alkaline dye bath (sodium carbonate), followed by a dilute sulfuric acid bath in which the red coloring matter developed. Because of its fugitive nature this dye was used often in combination with weld, brazilwood, or other dyestuffs. Authors of a number of dye manuals cautioned users that soap and wind “‘carried off” its colors. GUM-LAC (Laccifer lacca, formerly known as Coccus lacca) Also known as gomme-laque (Fr.); der Gummilack (Ger.) This dye was known for centuries in India before it was finally exported to England in 1796 (Bancroft, 1814, vol. 2, p. 13). A few years later it was imported into the United States, where it found a ready market throughout the remainder of the 19th century. Its popularity was due to reasonable price (half the cost of cochineal for which it substituted) and dull but very fast red colors. Lac dye was derived from the dried bodies of East Indian insects related to the cochineal-producing insect, Dactylopius coccus. These attached them- 28 = tes ONL)£PO I ISNSNOOY 28) i "(F691 “owog) IWS ey uo st ued ajoym fdjnd xv 07 s8uLaA0d poeas po}UaUTI0} ay} Sulonpol punoisos0oy Ul soaTeU YIM ‘T9]U99 Ul UMOYS SI }VA SuLyros {4Ja] oY1 uO st pod poses oy, AInjued YIZ] 23%] 9Y2 SulIMp poyordrojur se Sutssado1d (noono1) oyvUUY—/ AAAI] as ern = LSE, nee oneee ee = Se MOINO YT 2 puvnbrsgr e24h2 NT selves to twigs of trees of the genus Ficus on which they reproduced rapidly. After the insect bodies had formed a thick gummy red coating on the twigs, the twigs were broken off and sun-dried to kill the insects. Until about 1810 lac could not be purchased in any other form. It was a laborious task to grind the sticks and pound them into a powder, put the powder into water to dissolve the coloring matter, and then dispose of the remainder of the material (90 percent of the whole). An addition of alum precipitated the dyestuff that could then be filtered out and dried. Before 1810 a cake form of lac came on the market (Bancroft, 1814, vol. 2, p. 15), however, the quality of the cakes proved so erratic that dyers were discouraged from using them, usually preferring to process the dye themselves. The scarlet, crimson, and orange shades dyed with lac were not as brilliant as those produced by cochineal; therefore, brilliant cochineal was often combined with durable lac to make a very attractive, permanent dye, with the added advantage of being considerably less expensive than cochineal alone. SAFFLOWER (Carthamus tinctorius) Also known as carthamus; bastard saffron; carthame (Fr.); der Saflor (Ger.) The safflower plant, a native of Egypt and some parts of India, was cultivated in Europe for the clear pinkish-red colors it imparted to cottons and silks. Although probably used much more in Europe than in the United States, safower is mentioned in various 19th-century dye manuals. Professional dyers acquainted with its attractive colors may have applied it here. Unfortunately the clear reds extracted from safflower were not long-lasting due to its sensitivity to acids, alkalis, and light. These latter qualities greatly limited its usefulness. The flower head of this annual of the thistle family contains two coloring matters; water-soluble yellow that is unsatisfactory for dyeing and the alkali-soluble reddish dye. To extract the red dye the flower heads were first placed in a sack, crushed and washed in a stream of cold water until all soluble yellow color was removed. Then the reddish dye was extracted from the remaining mass of safflower heads by placing them in a weak alkali solution into which the cloth was also immersed. The most important application of this dye was in coloring cotton tapes used to tie together legal documents—the source of the original ‘“‘red tape” so familiar to bureaucrats. POKEBERRY (Phytolacca decandra) The dye extracted from pokeberries seems to have been used a great deal by home dyers; however, comments by professional dyers on the dye source always mentioned its short-lived color. 30 It was used as early as 1749, but even then Peter Kalm * expressed regret that no method had been found to fix the color on woolen and linen cloth (1772, vol. 1, p. 153). Many of the families who own old handwoven coverlets tell the story of grandmother gathering pokeberries and extracting their juice to dye coverlet wool deep jewel-toned reds. This is a rather unlikely possibility, unless our home-dyeing ancestors possessed some well-guarded secret methods of fixing the dye. Kermes and mungeet (or munjeet) are two other red dyestuffs worthy of passing recognition. These were frequently mentioned but apparently little used by dyers in America. Kermes (the genus Kermes) is a red dye of very ancient origin that, like cochineal, was derived from the dried bodies of insects related to cochineal- producing Dactylopius coccus. Its color was durable, but not as bright as cochineal’s. The kermes insects fed on a certain type of oak (Quercus coccifera) and were raised in Southern France, Spain, and along other sections of the Mediterranean coast. Mungeet (Rubia cordifolia), referred to as ‘‘R. munjista” by Bancroft and other 19th-century authors, is related to madder and produces a similar color. It was a very important dye in India for many centuries but only occasionally used in America, since madder could be obtained readily. YELLOW Dyes *FUSTIC (Morus tinctoria or Chlorophora tinctoria) Also known as old fustic; yellow wood; dyers’ mulberry; mora; bois jaune (Fr.); das Gelbholz (Ger.) Thomas Cooper’s opinion, expressed in his 1815 publication, was that fustic, although cheap enough to be commonly used, should not be employed in dyeing fine cloths. His contemporary Joseph Swartz agreed that it was a dull color yet in spite of it felt that fustic made a “‘good standing”’ dye. No two 19th-century dyers agreed exactly on the value of fustic as a dye for woolens, silks, and cottons, yet all included it among their stocks. The dye was used both for yellows and for compound hues made by combining yellow with other colors. It was frequently mentioned in recipes for snuffs, drabs, greens, oranges, and red oranges. An English navigation statute of 1661 lists fustic as one of the English colonial products that could be shipped from their place of origin only to other lands under English rule (Bishop, 1866, vol. 1, p. 87). Another indication of its early use here is the inclusion of 230 pounds of fustic among 4 Peter Kalm, a Swedish natural historian, in his Travels in North America recorded his observations on many dye plants used by colonists in the Middle Atlantic colonies and Southeastern Canada. Sil dyestuffs recorded in the inventory of a Boston dyer who expired in 1695 (Haynes, 1954, vol. 1, p. 46).° The ‘‘stockfish wood”’ referred to by Captain William Dampier, the adventurer who wrote a diary in 1676, was also fustic. Throughout the 18th century, apothecaries imported it from Brazil and a number of West Indian islands such as Jamaica, ‘Tampico, and Cuba. The tree that yielded the dye is a member of the mulberry family, and for that reason fustic was known as dyers’ mulberry. Asa Ellis, writing in 1798, gives a fine description: Fustick is much used in this country . . . It should appear when split of a bright yellow, tinged with the orange colour. The wood is close and hard; generally hard to split and full of splinters. The root and that part of the wood which is knoty is the best. It comes to us in large logs from six inches to one foot and a half through; if it be rotten, or other- wise injuried it will not answer well for Saxon greens; however, it may be employed in dark drabs (p. 20). Although generally purchased as logs or sections of logs, it was prepared for dyeing by first rasping or chipping into small fragments. The fustic then could be placed in the dyebath; however, it was often soaked in water for two or three days before being used, since the dye was released more readily if the wood was premoistened. Fustic and other dyewood chips were tied in sacks before being immersed in the dyebath so they would not splinter and tear the textile material and could be removed easily after dyeing. Alum was the standard mordant and was used often with cream of tartar. Some early dyers claimed that fustic would not impart a lasting color. This may have been due to improper mordanting or other unscientific dyeing techniques. Potassium bichromate, the mordant used in fustic dyeing today, was known but not used as a mordant until later in the 19th century. At least one 20th-century authority, a dye chemist writing in 1910, said that fustic combined with a chrome mordant was at that time still regarded by some as the best yellow coloring matter the dyer possessed. He further stated that it was fast to milling and soaping and stood light well. On exposure to light the shade became browner, but in many compound shades the change was not readily noticeable (Knecht, 1910, vol. 1, pp. 351-352). Fustic has been superseded by other yellow dyes, but not until after it provided several generations of dyers with an economical and reliable source of color. *QUERCIROTN (Quercus velutina) Also known as black oak; yellow oak or American oak; and known earlier as Q. nigra or Q. tinctoria 5 Original source is Suffolk County Probate Records, XIII, p. 743. 32 Mark Catesby, a mid-18th century English naturalist, described the black- oak tree as one whose wood was “‘of little use but to burn” (1771, vol. 1, p. 19). This erroneous judgment was corrected later in the same century by a fellow Englishman, Dr. Edward Bancroft, who returned from a journey to America with quite a different opinion. He had learned that black-oak bark yielded an excellent yellow dyestuff (he named it quercitron) that he believed could become a cheap substitute for weld. In 1785 the British Parliament thought highly enough of Bancroft’s idea to award him the exclusive right to use and apply it to dyeing and calico printing for several years. Black-oak bark “. . . was first sent to England before the Revolution from Wilmington, Delaware, where an export trade in the article was established soon after the Peace by one of the discoverers of its valuable dyeing properties” (Bishop, 1866, vol. 1, p. 461). Even before Bancroft published his discovery, American home dyers probably used the bark of this locaily grown tree for dyeing bright yellow woolens, cottons, linens, and silks. Only after it was introduced to Europe, however, did this indigenous American dyestuff take its place among the important vegetable dyes. It remained in commercial use until the second quarter of the 20th century. In his complete description of the preparation of quercitron bark, Bancroft stated that the greatest amount of coloring matter is found in the inner bark or cellular coat of the tree trunk. This and the cortical sections were ground by millstones to a fine powder. Apparently this method was not entirely satisfactory for in 1810, 1812, and 1822 patents were issued to Americans who had developed improved methods of pre- paring quercitron and its extract. Numerous other patents were issued during the 19th century to inventors of bark crushers, grinders, packers, etc., indicating continuous efforts to improve quercitron and other dye- wood processing. Usually the bark was mordanted with alum and cream of tartar and dyed according to the individual dyer’s recipe. A wide range of proportions of bark to wool were used—from 1! pounds of bark per 20 pounds of wool to 6 to 8 ounces of bark per 1 pound of wool. Bronson, in 1817, stated that the quercitron bark priced in New Ycrk for export was valued at $45 to $60 per ton (p. 192). Apothecaries and druggists in the York, Pennsylvania, area sold it at 12 cents per pound. Quercitron contained much tannin and was used by tanners as well as dyers, thus home dyers whose apothecaries could not supply them were able to purchase quercitron from tanners for as little as 144 cents per pound. Although quercitron was sold for a wide range of prices, it was still in- expensive compared to other purchased dyes (Lynde, 1831, p. 8). 33 4 Black oaks grow throughout Eastern United States, with Georgia, Pennsylvania, and the Carolinas supplying the greatest quantity. Al- though mainly used in wool dyeing, it was also applied to cottons and to a lesser degree, to silks. Recipes for drabs, smoke, olive, snuff, oranges, yellowed reds, cinnamon brown, and a range of yellow called for quer- citron alone or combined with other dyestuffs. Other Yellow Dyes Yellow-dyeing plants are everywhere. A complete palette of yellows, golds, and browns can be created from products of roadsides, forests, and gardens. From this wide range of possibilities only a few of the most widely used plants are mentioned here. Local supplies of dyes varied with the location of the dyer, the season, and the effects the dyer wished to achieve. ARSEMART (Polygonum persicaria) Also known as smartweed This weed, a member of the buckwheat family, grows along roadsides in many parts of the Northeast. During the 18th and early 19th centuries it was recommended by professional dyers because of the durable yellow color it imparted to woolens, cottons, and linens. Thomas Jefferson made no record of its intended uses, but he did list a species of arsemart (P. sagittatum) among the plants grown at his home in Charlottsville, Virginia (Jefferson, 1944, p. 644). Plants were cut while in bloom, then dried, and soaked for several days to induce fermentation. The dye liquid was then heated and alum- mordanted cloth immersed in it. One 19th-century dyer suggested its use in compound colors such as black, smoke, snuff, and green. ASH, WHITE (Fraxinus americana) Also known as fréne (Fr.); die Esche (Ger.) The bark of the white ash produced a dye valued for the beauty of its clear yellows and tans and for its colorfastness. It could be prepared ““esreen or dry, boiled or simmered”? and was especially useful when nut- galls were unavailable. BARBERRY TREE (B erberis vulgaris) Also known as epine-vinette (Fr.); die Berberitze (Ger.) Thomas Cooper mentioned that barberry root was imported to Pennsyl- vania from Boston, and that its fruit made ‘‘an excellent tart, and a beautiful pickle’? (1815, p. 20). Besides these valuable properties, barberry supposedly produced a fugitive but rich, bright yellow dye without mordants. It was used by leather dyers and in textile dyeing when combined with other more permanent coloring agents. ook *CHROME YELLOW (Lead chromate) Also known as das Chromgelb (Ger.) Chrome yellow dye was probably introduced into America in the 1830s after it became known in Europe. This mineral dye was fast when applied to cotton; however, it was very fugitive to light, soap, and acids when applied to wool. It was considered the best yellow cotton dye throughout the second half of the 19th century and continued in use in the 20th century. The dyeing technique required two steps: First, successive steeping in basic lead acetate, followed by squeezing off; and second, immersion in potassium bichromate to develop the mineral color. By the latter step insoluble lead chromate or chrome yellow was developed on the fiber. Chrome mordant (potassium bichromate) was first patented in 1840 by a Leeds, England, cloth manufacturer (Fierz-David, 1953, p. 3633). After its introduction to American dyers in the 1840s it became a staple mordant. DOCK (Rumex sp.) Also called Peterswort; patience (Fr.); der Ampfer (Ger.) Like smartweed, this member of the buckwheat family produced a yellow dye commonly used by home dyers. Within the last one-hundred years a variety of dock native to the American Southwest has also been used by Navajo Indian weavers and dyers for coloring their rug and blanket yarns. The roots and leaves of this plant afforded a yellow color that made a “eood duck’s wing green’? when combined with other dyestuffs. It is mentioned in a number of late 18th and 19th century dye manuals. DYER’S BROOM (Genista tinctoria) Also known as dyer’s weed; greenweed; woodwax; woodwaxen; genestrolle (Fr.); der Farberginster (Ger. ) Dyer’s broom is not indigenous to the United States; however, it could have been cultivated here had there been a sufficient demand for it during the late 18th and early 19th centuries. It was imported ground and packed in casks. The greenish-yellow color it imparted to woolens was fast; because its natural greenish cast combined so well with blue, it was frequently used to top blues in green dyeing. An entry in a 17th-century English volume mentioned it among the three yellows used in England at that time; the other yellows were weld and old fustic (Sprat, 1667, p. 296). *GOLDENROD (Solidago species, mainly S. virgaurea) Also known as verge d’or (Fr.); die Goldrute (Ger.) and called S. canadensis by Hollberg (1763, p. 5) and other early botanists Many professional dyers acknowledged the clarity and fastness of golden- rod yellows, but for some unknown reason this native American plant was used mainly by home dyers. Its abundance and reliable colors should have made it popular with professionals, yet they paid comparatively little attention to this excellent source of yellow. 35 Goldenrod was applied to alum-mordanted wool and was suggested as a substitute for weld in calico printing as well. It is mentioned by the nat- uralist Peter Kalm in his mid-18th-century publication, but it was certainly used by American colonists before that time. Home dyers throughout the 19th century used goldenrod in areas where it grew. Goldenrod was gathered just as it was beginning to bloom; its flowers could be dried and stored until needed. *HICKORY (Carya tomentosa or Hicoria tomentosa) Also known as hiccory; mockernut; white hickory; das Hickoryholz (Ger.) Although the color of hickory bark was strong and stable it was apparently of little interest to commercial dyers of yellow woolen textiles. It is men- tioned several times in home dyeing manuals, sometimes as a substitute for turmeric or fustic. This tree, common along the entire east coast of America, was first noted here by a 17th-century observer, later mentioned by Mark Catesby, and in 1749 referred to specifically as a yellow dye by Peter Kalm. Bancroft in the late 18th century thought enough of its dyeing possibilities to have it patented as a greenish yellow dye (Bancroft, 1814, vol. 2, p. 164). Bancroft derived no profits from his patent though for a number of reasons: The yellows it produced were duller than those made from other dyes; its bark was tough and difficult to grind; the more con- centrated quercitron was already successful commercially and there was no need to add hickory bark to the long list of available yellow dyestuffs. Hickory bark is not mentioned by professional dyers writing after the mid-19th century. PEACH (Prunus persica, known earlier as Amygdalus persica) Also known as péche (Fr.); der Pfirsich (Ger. ) A yellow dye was prepared from peach (and pear) tree leaves and bark during the 18th and 19th centuries. It was applied mainly by home dyers to alum-mordanted wool. Bronson believed the dye was more durable than fustic and recommended in his recipe that as much as could be crowded into a kettle should be used for each dye lot, indicating that its color was not too concentrated. *PERSIAN BERRIES (Rhamnus species, including R. infectoria and R. tinctorius) Also known as berries or grains of Avignon; French berries; dyer’s buckthorn; der Kreuzdorn (Ger.) Persian berries were well known in France during the 17th century; in America they were probably used by professional dyers during the 18th century and the first half of the 19th century. This dye never achieved great popularity here because so many less expensive yellow dyes were readily available, including the excellent quercitron, native to America. Various common names of this dye were derived from its places of origin. For example, some Rhamnus species were grown in Persia (and Turkey)— 36 thus the name Persian berries. They also grew in southern Europe— “grains of Avignon” is derived from the town of Avignon in southern France. The shriveled yellowish-green berries were gathered before ripening, then dried, and when ready for use were ground into a powder. Tin mor- dant gave woolens colored with this dye bright yellow and orange shades, which turned brown when exposed to light. Copper mordants produced lightfast yellow-olive shades. Persian berries were used in wool and calico printing, in addition to their use as a cloth dye. *SASSAFRAS (Sassafras albidum, called Laurus sassafras by P. Kalm) While visiting the Philadelphia area in 1748 Peter Kalm learned that local residents used the bark of the sassafras tree as a dye and its leaves as a tea. The bark was used for dyeing worsted a fine lasting orange color, which was sunfast. The wool was dyed in a brass boiler, with urine used in place of the usual alum mordant (Kalm, 1772, vol. 1, pp. 114-115). Later Asa Ellis told of the light brown and ash colors it produced and of its ability to leave cloth soft and pliable. He also believed that this bark was profitable to country dyers when they did not have a supply of nutgalls. Only one 19th-century dye manual lists sassafras among its dye ingredi- ents, implying that, although it was readily available along the east coast of America, professional dyers of the time did not rely on it because similar results were obtained with other substances. There is a strong possibility, however, that home dyers continued to use sassafras during the 19th century when they lived near a source of supply. TURMERIC (Curcuma longa) Also known as turmerick; turmerech; curcuma; terre merité (Fr.); das Kurkumagelb (Ger.) Yellow dyes were extracted from the ground root of the turmeric or Indian saffron plant. This bright orange powder was a rich but fugitive dye, considered the finest yellow by many professional dyers and used frequently throughout the 18th and 19th centuries. Turmeric was the only yellow dye that did not require a mordant to fix it on wool, cotton, or silk; but its sensitivity to light, soap, and alkali reduced its value considerably. It was used principally in combination with other dyes to make browns and olive greens. WELD (Reseda lutea) Also known as wold; dyer’s weed and dyer’s mignonette; rés¢da des teinturiers (Fr.); der Wau (Ger.) This excellent dye may have been the most common yellow dye used in England until the advent of synthetic dyes. Although it was employed by 37 1 Coegyeria Tih eophr aité . Venice Sumach, Ficure 8.—Young fustic plant (Gerard, 1597). Library of Congress photograph (LC- 25901). American dyers during the 18th century it was never used a great deal in America. Its cultivation here is mentioned briefly and hopefully by a few dyers; however, limited demands appear to have been met by importation of weld from England. Besides being expensive, great quantities of the dried branches and stems were needed and its bulk added to the difficulty of shipping. Gilroy, in 1859, criticized a fellow dyer, William Partridge, for his lavish praise of weld, remarking that Partridge is completely in love with weld as a tinctorial substance. This dyewood is indeed, as every practical man knows of great value; but nevertheless, we are not prepared to go to the same extent in its praise, that Mr. P. has: “‘(its) ... color... (is) more permanent . . . than any other yellow dye . . . but its chief superiority consists in. . . a very superior degree, of imparting a great degree of softness to the woolens dyed with it” (Gilroy, 1859, p. 127). 38 Weld was cultivated in France and also grew wild in Italy at one time. The upper part of this herbaceous plant, especially the leaves and seeds, were chopped for dyeing, along with the stem that contained less coloring -matter. Large amounts of weld were required, since its coloring matter was not concentrated. Processing was generally similar to that of fustic and quercitron bark. Although weld is best known for its bright yellow hues, various mordants and different fibers combined to create hues ranging from yellow to yellow olive. Wool and cotton will dye olive-yellow with chrome; copper mordant dyes wool yellow-olive; alum, yellow; and a very bright yellow could be achieved in silk using a titanium mordant. Most early 19th-century dyers’ mixed results were caused by their almost universal use of the alum mordant. By 1920 weld was no longer used in England and had not been in common use in the United States for a number of years. YOUNG FUSTIC (Cotinus coggygria, also known as Rhus cotinus) Also known as Venice sumach; fustel or fustet (Fr.) This dye, obtained from a small tree of the sumach family, is botanically unrelated to fustic, the well-known tropical dyewood. Both impart yellow- orange colors to textiles, but young fustic is so fugitive to light that its usefulness has always been limited. The stems and trunk of the tree Cotinus coggygria, native to the West Indian islands and southern Europe, were cut and gathered into small bundles for export. Dyers rasped or cut and boiled young fustic to extract its dye. Usually it was combined with other, more permanent dyes to heighten their hues, leaving behind a fast color when its temporary hue had vanished. Brown Dyes *BUTTERNUT or WHITE WALNUT ( Juglans cinerea) and *BLACK WALNUT (f. nigra) Butternut and black-walnut trees belong to the same botanical genus and have common dyeing properties. Although certain color differences may be noted, methods of extracting the dyes are similar, thus both varieties are discussed together. Americans knew the art of extracting rich and durable browns from the roots and nuts of native walnut trees as early as 1669, when Governor Winthrop of Connecticut sent the following report with samples of butternut dyeing to the Royal Society of London: Shreds of stuff made by the English planters of cotton and wool, put up to shew the colour, which was only dyed with the bark of a kind of walnut-tree, called by the planters the butter-nut-tree, the kernel of that sort of walnut being very oily, whence they are called butter-nuts. They dyed it only with the decoction of that bark, without allum or copperas, as they said (Birch, 1756, vol. 2, p. 418). 39 In the mid-18th century Peter Kalm observed that women in Pennsylvania and New Jersey used black-walnut bark and nut husks to dye wool a lasting brown. Thomas Cooper, in 1815, stated that usually the green hulls or rinds of the walnut were used for dyeing browns. The roots’ inner bark—sometimes referred to as walnut bark—was also used, even though it was less potent than the rind. Since no mordants were needed for walnut and butternut dyeing, the vegetable material could be boiled for a certain period and the wetted cloth dipped until the desired color had been achieved. Besides producing browns, walnut dye was often used to ground fabric in preparation for black dyeing, or for black dyeing as explained in an anonymously written 1811 dye manual: Black is sometimes dyed without having given it a blue ground, but this ought to be only for stuffs of inferior quality . . . butternut bark put in an iron kettle, if (allowed) to remain long enough will dissolve enough of the iron to make a tolerable black, as the experience of many women has demonstrated, in coloring stockings (p. 39). *CATECHU; also known as cutch; cachou (Fr.); das Katechu (Ger.) from Acacia catechu, sometimes called Bengal catechu from Areca catechu, sometimes called Bombay catechu GAMBIER (Uncaria gambir); also known as gambier catechu and gambia Catechu, the last important vegetable coloring agent added to the professional dyer’s repertoire, was used in Indian calico printing long before its advantages were realized in Europe and America. This brown dye was first applied to European printed cottons around 1800 in Augs- burg, Germany (Persoz, 1846, vol. 3, pp. 98-99). One American scientist who compared the properties of catechu and chestnut bark in 1819 men- tioned that catechu was discovered “12 or 15 years” earlier (Sheldon, 1819, p. 148). It is difficult to ascertain how widely it was used in America during this early period. Thomas Cooper mentioned its use as a substitute for galls in 1814. The process apparently was little used in France until 1829, however, when M. Barbet of Jouy exploited this secret process to great commercial advantage for three years. During the 1830s catechu came into general use in Great Britain and America, where rapid strides were made in improving methods of application. The name “terra japonica’? was sometimes applied mistakenly to this brown dye because it was believed to be an earth found in Japan. Actually three different Mideastern plants produced this excellent dyestuff. Bengal catechu was an extract from the heartwood and pods of Acacia catechu, a leguminous East Indian tree. Bombay catechu was produced mainly by areca or betel nuts, the fruits of the tropical Asian betel-nut palm, Areca catechu. Gambier was an extract made from the leaves and twigs of a vine that grew in India and the Malacca Islands, Uncaria gambir. 40 The following excerpt from an 1846 dyer manual clearly describes the processing of Acacia catechu and would also apply generally to the other types: As soon as the trees are felled, all the exterior white wood is carefully cut away, the interior or colored wood is then cut into chips; narrow mouthed unglazed pots are nearly filled with these, and water is added to cover them and reach to the top of the vessel. When this is half evaporated by boiling, the decoction without straining is poured into a shallow earthen vessel, and further reduced two-thirds by boiling. It is then set ina cool place for one day, and afterwards evaporated by the heat of the sun, being stirred several times during that process. When it is reduced to a considerable thickness it is spread upon a mat or cloth, which has been previously covered with the ashes of cow- dung. This mass is divided with a string into quadrangular pieces, which are completely dried by being turned frequently in the sun, and are then fit for sale. It is a brittle compact solid, of a dark brown or chocolate color . . . ({Parnell], 1846, pp. 59-60). Catechu and gambier were applied to cotton, silk, and, to a lesser extent, wool. Its natural brown color could be modified with various compounds to produce olive, drab, and gray tones. Since catechu and gambier extracts were soluble in boiling water, the application of this dye was comparatively sumple. In coloring cotton and wool the dye was boiled with the cloth and a copper salt added. This bath was allowed to stand for several hours, then the cloth was removed, washed, and dried. In order to assure lightfastness and deeper shades, copper salts were recommended by early 20th-century dye chemists. Gambier was used in black-silk dyeing as late as the first quarter of the 20th century mainly because it could be applied along with metallic salts in weighting silk. A U.S. Tariff Commission report on natural dyestuffs imported into the United States between 1910 and 1917 reveals that gambier was by far the most important dye brought into this country, both in terms of quantity and monetary value (1918, p. 56). Although such a survey, recording pounds of extract along with pounds of raw materials (such as woods), cannot be considered a completely valid basis of com- parison, it does suggest strongly that gambier far outranked in importance any of the other dyes surveyed. By 1917 the quantity of most natural dyes, including gambier, had diminished considerably, yet they were still used in amounts great enough to be recorded. Between the First and Second World Wars the dye industry made such strides that this natural dye, along with all others, has become obsolete. Other Brown Dyes BARKS OF VARIOUS TREES ALDER (Alnus sp.) Also known as oler or owler; aune (Fr.); die Erle (Ger.) It was natural for home dyers living in a heavily forested country like America to search for coloring materials among the barks of trees which 4] surrounded them. The most frequently mentioned brown-coloring barks were tannin-rich alder, hemlock, and maple. Use of these probably de- pended to a great extent on availability. A New York State dyer said that alder bark was not much used in America, except in the small domestic dye; yet other dyers of the period mentioned it frequently enough to suggest that it was generally known, either as a dye or as a substitute for sumach or galls in black dyeing. William Partridge, the New York dye merchant, described the gathering and use of alder bark in this way: . . . The sticks are cut in the month of April, or the beginning of the month of May, when the sap runs; the bark is stripped off as soon as cut, (which is easily done by chil- dren) and is dried in the shade, when it is fit for use. The poles make good bean sticks, or excellent firewood. This bark, when the colouring matter is strong, produces a brownish drab with alum, and a light forest drab when only a small quantity is used. When employed in the black dye, it increases the body of the colour even more than sumach, and is equally durable (1847, pp. 38-39). According to various other dyers it imparted brownish and fawn colors, yellow oranges or drabs to silk, wool, or cotton, depending on dyeing procedures and mordants used. Dye potentials of the native alder tree were never fully exploited in America. Alder bark (from Alnus glutinosa) was much used by European dyers because of its high tannin content. According to William Tucker, however, the dyeing quality of the alder grown in this country was equal to the imported variety. It was noted by Bancroft after his late 18th- century journey to America and was also mentioned by Asa Ellis in 1798 as a good and durable dye, “‘useful in almost all dark colors.” Although professional dyers working in the second half of the 19th century may have found other brown dyes more valuable, it was still mentioned by O’Neill as late as 1869. Probably its principal users later in the century were home dyers. * HEMLOCK ( Tsuga canadensis) Also called spruce pine or hemlock spruce; cigué (Fr.); die Hemlocktanne (Ger.) Hemlock bark provided settlers of Eastern United States with another good source of reddish-brown dye. Peter Kalm and Joseph Bancroft both applied the scientific name Pinus abies to this tree, known as Tsuga cana- densis to today’s botanists. This dye was applied to both wool and cotton and employed in tanning leather in Nova Scotia. When combined with an alum mordant it resulted in a durable bright reddish-brown hue on wool and an impermanent nankeen (brownish yellow) on cotton. Cop- peras mordant produced dark drab and slate colors. RED MAPLE (Acer rubrum) Also known as swamp or scarlet flowering maple O’Neill dismissed red maple in his Dictionary of dyeing and calico printing as not having been mentioned in recent works on dyeing, and he stated ae that it probably never had been used. This statement may indicate that by 1869 red-maple dye was obsolete; however, it definitely was known and used in America during the 18th century, as indicated by Peter Kalm’s description of its application in the Philadelphia area in 1748: With the bark they dye both worsted and linen, giving it a dark blue colour. For that purpose it is first boiled in water, and some copperas, such as the hat-makers and shoe- makers commonly make use of, is added, before the stuff (which is to be dyed) is put into the boiler. This bark likewise affords a good black ink (1772, vol. 1, pp. 131-132). Certainly maple bark would have been an uncommon source of blue dye; in fact one suspects that its “blue” was closer to the “‘slate” color mentioned by other authors who combined maple bark with copperas (ferrous sulfate). In addition it was used in black dyeing, sometimes substituted for white-oak sawdust or sumach, and was also known to give “lasting” cinnamon-brown tones to wool and cotton when used with an alum mordant. PuRPLE Dyes ORCHIL (originally from Rocella sp., esp. R. tinctoria) Also known as archil; orchille; orseille (Fr.) Orchil is an ancient dyestuff derived from several different varieties of the lichen Rocella, which grew on rocks along the Mediterranean coast. During the early 18th century a new source of Rocella was discovered in the Canaries; a few years later it was found in the Cape Verde Islands. These areas supplied most of the orchil used in Europe and probably America until the 19th century. India and Ceylon supplied England with Rocella in the 19th century, mainly due to decrease in quality of Rocella supplied by island sources (Kok, 1966, p. 259).6 American dyers imported the dye processed and ready for use. It may have been used here for dyeing wool and silks during the 18th century, however, it is not mentioned in American dyers’ manuals or advertisements until the early 19th century. One of the few substantive dyes, orchil produced beautiful but light- sensitive colors which included the whole range of hues between red and blue. One American dyer writing in 1869 stated: It is seldom used by itself for dyeing, but usually to help or top other colors; when used alone it can give very agreeable shades of violet, peach, and lilac, which colors are very loose in air, fading almost visibly in sunlight; in combination with other coloring mattersit usually darkens them, giving chocolate colored shades; but archil is chiefly valued for a peculiar softness and velvet bloom it communicates to colors (O’Neill, pp. 68-69). In processing orchil, whole lichens were first steeped in an alkali such as fermented urine or slaked lime which were used often during the late 18th and early 19th centuries. This mixture was allowed to set for about a week until it turned deep purple. After three more weeks, without the 6 This article gives a complete history of orchil dyeing. 43 addition of urine or lime, the “‘urinous volatile spirit” of the dye was replaced by a violet scent and the liquid had turned crimson. Then blue or red orchil could be made by simply adjusting the solution’s alkalinity. This material was dried and sold in paste or cake form. After the mid-19th century it could be purchased in America as a liquid as well as a paste (O’Neill, 1869, p. 68). The basic technique of dyeing with orchil was very simple. Requiring no mordant, the dye was added to lukewarm water, slowly heated to the boiling point, and the textile material added. The dyebath was then reheated slowly to just below the boiling point to obtain the brightest colors. The whole dyeing process was repeated as many times as was necessary to obtain the depth of color desired. Alum or iron salts added to the dye would not improve its fastness, however, they modified its hues; iron salts turned orchil-dyed cloth rich reddish purple, while acids and alum had a reddening effect (Kok, 1966, pp. 264-265). After the advent of coal-tar dyes, orchil’s use gradually declined, but in spite of this dye’s sensitivity to light and milling it did not become obsolete as a textile dye until the first half of the 20th century. The soft, rich tones it imparted to wools kept it commercially useful until manufacturers could produce dyes that gave the same effects. A number of 19th century dye manuals mentioned another type of orchil made from the “‘lichen parellus” (Ochrolechia parella) that grew in the Auvergne region of France. Its processing and dyeing methods were essentially the same as orchil’s and apparently it was used along with the aforementioned and more durable orchil; however, its use was probably less general. CUDBEAR (a compound consisting of Ochrolechia tartarea {later Umbilicaria pustulata], Urceolaria calcarea and Cladonia pyxidata) Also spelled “‘cut bear” and “‘cudbierd’’; teinture d’orseille (Fr.) Cudbear is a dye closely related to orchil, since both are derived from lichens and contain the same coloring principle. Cudbear consists of a combination of lichens; it was patented in 1758 by a Scottish merchant named Cuthbert Gordon, who named it for his mother whose maiden name was Cuthbert (Kok, 1966, p. 257). It became popular with British dyers because, besides being made entirely from lichens found in the British Isles (these grew in Norway and Sweden also), it was sold in powdered form, which simplified application and storage. Some American dyers of the 19th century considered cudbear too fugitive to be important; others suggested it might even be sought for possible commercial exploita- tion in this country. Litmus and _ turnsole, infrequently mentioned in American dyers’ manuals, were made from lichens also. Litmus, still used as an indicator 44 of alkalinity or acidity (red for acids, blue for alkalis), was made first from O. tartarea, the chief ingredient of cudbear, and later from Rocella and other lichens. Turnsole was another kind of litmus, sometimes used for coloring Dutch cheese (Kok, 1966, p. 264). BLACK DyEs *LOGWOOD (Haematoxylon campechianum) Also called Campeachy wood or blackwood in English; bois d’Inde and bois bleu (Fr.); das Blauholz (Ger.) The bloody disputes which this useful Tree has occasioned between the Spaniards and the English, are too well known to say much of here . . . (I wish) . . . that the inhabitants of our Southern plantations could be induced to propagate it, as well for their own advantage, as that we may be supplied by them, when wholly deprived of getting it from the Spaniards, as we have hitherto done, either by force or stealth. This statement written by Mark Catesby in a volume first published in 1731 suggests that conflicts over logwood trade were fairly common during the early years of the 18th century (1771, vol. 2, p. 66).’ Probably logwood was introduced to England soon after Queen Elizabeth ascended the throne. A few years later, about 1581, a law was passed prohibiting the use of logwood because the colors it produced were so fugitive. The truth is that too little was known about mordanting pro- cedures to fix the dyes on the fibers properly at that time. The logwood prohibition laws were repealed nearly a hundred years later during the reign of Charles IT. The earliest English settlers must have brought it with them to the American colonies for it seems to have been known here during the 17th century (otherwise it would not have been referred to in the Navigation Acts of 1660 and 1671). Although logwood is not named specifically in these acts, the “‘other dyeing woods” mentioned very probably refer to logwood. The wording of the acts strongly suggests that logwood was used in the colonies as early as the third quarter of the 17th century (Bishop, 1866, vol. 1, p. 87). At that time American ship owners began to carry on an active trade with non-British ports even though the Navigation Acts expressly forbade such dealings. Currency was needed and this valuable dyestuff which was easily sold in foreign ports brought in needed currency. Logwood grew naturally in Central America, Mexico, and parts of northern South America. From Spanish-controlled Campeachy and British-owned Honduras it was brought to Jamaica and other West Indian 7 The third edition of a publication that first appeared in 1731 (vol. 1) and 1743 (vol. 2). These volumes were based on Catesby’s observations made between 1712 and 1726. 49 islands where it was successfully propagated. The trees, which attain a merchantable size in 12 years, were shipped in the form of logs 3 to 12 feet long. This cargo proved valuable not only for the good price it brought but also because it could be taken on as ballast. According to William Partridge, writing in the 1840s, the best logwood came from Campeachy, with lesser grades coming from Santo Domingo, Honduras, and Jamaica, in that order. Jamaica was the distribution point from which New England-based ships sailed for Atlantic ports all along the east coast between Charleston and Boston, and then on to English (and continental) ports. Privateers of the period were often spared the efforts of logging by capturing Spanish vessels laden with this valuable commodity. Logwood was sold by apothecaries and in general stores, as evidenced by frequent advertisements in 18th-century newspapers which list logwood among their various other wares. It was generally sold in the form of logs that had to be rasped or broken down in some other manner before they could be used. This process could have been carried on in mills, either before or after purchase. Since buyers always feared adulteration, however, logwood was frequently purchased in log form and then rasped or chipped later by the consumer. One Pennsylvania newspaper advertisement of 1798 informed its readers that, among other items produced by inmates of the Philadelphia prison, chipped logwood could be had on reasonable terms. Dyeing with logwood was a comparatively simple matter. Only the reddish heartwood was used, with the outer parts chopped away before shipping. First the rasped or chipped wood was dampened with water and allowed to “‘mature”’ or ferment slightly for a few days. This fermented wood was then gathered in a sack and immersed in the dye kettle. After being boiled for 20 minutes or more the bag containing logwood chips was removed and the textile material was submerged in the clear coloring liquid. Mordanting could take place either before, during, or after dyeing. Logwood was used on cotton, silk, and wool, with the hues produced depending on the particular mordants chosen. Logwood was most important in black and blue dyeing; although it produces other colors, such as silvery grays and purples, they are extremely fugitive in light. A good navy blue could be made when the textile had been mordanted with potassium bichromate; however, although this com- pound was known around 1800, it does not appear to have been used as a mordant until much later in the 19th century. Instead, copperas, blue vitriol, and verdigris were frequently utilized in dyeing navy blues that contemporary dyers considered beautiful and which were definitely cheaper than indigo blues. 46 In 1798, Asa Ellis said that woolen yarn for coverlets and stockings could be advantageously colored with logwood. He did not fully explain whether logwood-dyed textiles would prove more profitable to the dyer or the consumer. Other 18th- and 19th-century dyers considered logwood blues poor substitutes for indigo, because although they were lower in price they faded when exposed to light. In France at that time logwood was frequently added to indigo dyebaths for fuller and richer blues. The most important application of logwood was in dyeing blacks, which continued throughout the first third of the 20th century. Since black was considered a compound color many dyers felt that it required a combination of dyes, each of which yielded a different tone. Thus a black recipe might use logwood and sumach for their black tones, fustic for yellow, and a metallic oxide such as copperas which in the process of oxidation fixed the black. Sometimes 18th- and 19th-century dyers used so many ingredients and such great quantities of them to reinforce the effects of logwood that even without it the dye solutions might have yielded the desired deep black tone. Now logwood is no longer commercially valuable; however, it has certainly proved to be history’s most tenacious natural dyestuff, defying substitution almost until the beginning of the Second World War. NEuTRAL Dyes Most of the dye materials included in this grouping imparted color to textiles; however, their main value lay in their mordanting power. For this reason tannin-rich nutgalls and sumach, the most widely used among these substances, were considered essentials in every dyer’s shop. BARKS OF VARIOUS TREES *BIRCHES, known as bouleau (Fr.); die Birke (Ger.) Yellow birch (Betula lutea) Cherry or black birch (B. lenta) White, paper, or canoe birch (B. papyrifera) The barks of several varieties of birch trees were utilized in dyeing, mainly in light browns, blacks, or other drab colors. Peter Kalm mentioned Betula alnus, which referred to a variety of birch used in the mid-18th century. In 1869, O’Neill informed his readers that birch bark was “employed in dyeing, but principally by the peasantry” (p. 77). *O AKS, known as chéne (Fr.); die Eiche (Ger.) White oak (Quercus alba) Red oak (Q. rubra) Chestnut oak (Q. prinus) Quercitron or black oak was most famous for the fast and bright yellows it imparted to textiles. Other native oaks, however, were also utilized by 47 18th- and 19th-century dyers, for they too contained tannins and other dyeing agents which would give woolens stable colors. Peter Kalm mentioned three different oaks that were used in mid-18th- century dyeing. Red oak produced yellows, chestnut oak was used in reds, and white oak was utilized by New York dyers to color wool brown or “Thée bou” (muddy tea) color. The latter dye was not bleached by the sunshine (Hollberg, 1763, p. 3).8 Standard procedures for dyeing with bark called for stripping it from the trees, chopping it into fine pieces, and boiling it. Alum-mordanted cloth was usually immersed in the dye liquid when the barks were used for plain yellows, drabs, or browns. Compound shades or black dyeing involved complicated recipes which included the bark plus many other ingredients. One such compound black recipe designed to color 16 pounds of cloth (probably cotton) called for the following: 12 oz. argol, 6 oz. verdigris, 6 Ibs. logwood, 244 lbs. sumach, \ lb. fustic, 7 lbs. white-oak sawdust, and 3 lbs. copperas (Partridge, 1847, p. 57). Swamp-maple bark could be substituted for the oak sawdust and sumach. For an unusually rich and full-bodied color, the black cloth could then be put into liquid in which alder bark and black-walnut hulls had been soaked. The various oak barks were certainly used by professional dyers during the first decades of the 19th century; however, there is little indication that they were in common use by any but home dyers after the 1850s and 1860s. *TRON BUFF Each of the metals . . . is capable, when dissolved, of becoming a basis or mordant, for fixing and modifying some at least of the different adjective animal or vegetable colouring matters, with more or less advantage, by dyeing. But besides this property . . . several metals . . . afford coloured solutions or oxides, which are capable of being united and fixed directly in the fibres of linen, cotton, silk, or wool, and of thereby producing various permanent substantive colours (Bancroft, 1814, vol. 1, [Os 24018) Of the above-mentioned compounds iron oxides were most important for both mordanting and dyeing. They were a very common, albeit dull, source of color in household dyeing throughout the 18th and 19th centuries. Often bits of old iron, such as nails, were soaked in acid, such as vinegar, before a buff dyeing session was planned. An 1811 source suggested that iron liquor could be made by filling casks with scraps of iron and filings on which vinegar or sour beer was poured and left to stand for several weeks. 8 Hollberg’s publication, a Master’s thesis, was based mainly on the observations of his major professor, Peter Kalm. 48 Professional dyers, although generally more sophisticated in their methods, utilized the same raw materials for dyeing buff-colored cottons. A typical recipe, by Thomas Cooper in his 1815 manual, stated that buffs could be made by dipping textile material in a hot copperas solution, taking them out, wringing, opening and airing them, then raising the color in lime water. This procedure was repeated until the desired depth of color was reached (p. 309). The above directions for iron buff dyeing are typical of those found in dyers’ books until after the middle of the 19th century, when the buffs seem to have become unfashionable with the advent of the rainbow of clear, fresh colors and new methods introduced by scientifically oriented dyers. Copperas (ferrous sulfate) was the main ingredient in dyeing cotton buff color. Hazael Warfield, in his Clothier’s guide, explains the composition of copperas in this way: Copperas is an extract of Iron corroded with acid, or for a substitute for copperas, take the filings of iron put it in vinegar, let it stand one month and you will have a much better darkening substance; the best copperas is the brown or that which appears to be mouldy, deep green copperas will make the brightest blue but it is not so strong as the other, and will not make so good a black, that of a pale green colour is worth but little. Copperas ought to be kept in a cellar where it is not very damp nor open that the acid may evaporate (1832, pp. 27-28). While one might deduce correctly that iron buff would not necessarily produce a lively color, it was expected to last for the life of the textile. Many times this was true, but with faulty dyeing procedures, the textiles themselves were sometimes rather short-lived. Iron salts, especially those applied in large concentrations, caused textiles to become brittle and tender. Bancroft noted that most people had observed examples of iron spotting (then called iron-mould) on linens which produced holes long before any occurred in the body of the cloth. This effect can be noted in some early printed textiles in which one colored figure, usually brown or black, has been completely disintegrated because of the corroding effects of its iron mordant. Thus a well-dyed buff-colored cotton retained not only its color but also its strength throughout a reasonable period of use. Regarding the color itself, buff seems to have covered a considerable range of values and intensities of red-yellows. The generally accepted version is a somewhat brownish yellow, originally the color of oil-tanned calf or goatskin “buff leather. Although buff was originally derived from the Italian word ‘‘bufalo” it referred to the common European ox, rather than the buffalo that roamed our Western Plains. 49 GALLS Also known as nut-galls or gallnuts, noix de galle (Fr.); der Gallapfel (Ger.) The galls used in dyeing are nutlike in appearance and are actually infections on trees caused by certain insects. They are formed when female gall-wasps (Cynips gallaetinctoriae) puncture the young buds on small branches of certain species of oaks (especially Quercus lusitanica) and de- posit their eggs within these punctures. This action stimulates surrounding plant tissue to grow, eventually enveloping the gall larvae which con- tinue to develop. If allowed to reach maturity, the insect punctures the gall and escapes. The bluish or greenish-colored galls collected before the insects leave them were richest in tannic acid. Other factors affecting tannic acid con- tent of galls were the region in which they were grown and their harvesting season (August and September were best). The finest blue galls were imported from Aleppo, Syria; slightly inferior qualities were those from Smyrna, Turkey, and Tripoli, Libya. Galls of the same type were also found in southern Europe on the Q. sessiliflora and Q. pubescens oak species (Thorpe, 1912, vol. 2, p. 647). Although several 19th-century dyers voiced the opinion that galls could be cultivated on American oak species, no commercial amounts were ever produced here. Galls were purchased either in powder or nut form; however, since there was always great danger of adulteration when one purchased dye materials already ground, whole galls were preferred. Galls dyed only grays, and in compound colors, grayed yellows such as drabs. Their most important use was in mordanting, rather than dyeing, and they were most valuable in mordanting cottons that would later be dyed dark neutrals or black tones. With few exceptions most natural dyestuffs would not produce fast, deep colors on cottons without preparatory treatment by tannin-rich substances such as galls. Since tannin is the principal component of galls, making up 25 to 70 percent of the chemical composition of the nuts, it is obvious that galls held an important place among dyers’ supplies. O’Neill reminded dyers of still another property of galls—an ability to weight silks, giving them body without the aid of metallic salts: In the better class of blacks upon silks, galls are still much used; they give a very durable but somewhat grayish shade of color, and possess a property, very much esteemed in certain trades, of weighting, i.e., accumulating on the fibre in such quantity as to add very materially to the weight of the silk (1869, p. 231). Generally black dyers combined galls with iron salts and logwood;> adding madder and any other coloring material that would attain the tone of black the customer or fashion dictated. 50 One 18th-century recipe for dyeing 20 yards of fulled cloth an ash color called for 3 or 4 tablespoonfuls of the “flour of Nut-galls” to a piece of alum about the size of “a quail’s egg’? and a teaspoonful of copperas. Such recipes, typical of those employing galls around 1800, suggest how unscientifically some American dyers approached their craft, even when they urged their colleagues to consider dyeing as a scientific application of chemical principles. Bronson, recognizing the plight of the small-scale dyer in having to purchase galls at high prices, suggested that, if used in sufficient quantity, sumach could be used as a substitute. Other dyers suggested substituting catechu, myrobalans (the fruit of trees of the East Indian Terminalia species), valonia nuts, and certain tree barks such as alder, chestnut, and oak. All of these substances contained varying percentages of tannin, and if used alone or in combination with galls could save the dyer considerable amounts of money. Galls were used until the early part of the 20th century. Tannic acid today still has applications in certain dye processes, as well as in medicine. SOOT Also known as Suie (Fr.); das Sott (Ger.) Soot certainly could not be considered among the most important coloring agents used by early dyers. Its use does, however, illustrate the ingenuity of our ancestors in finding dye materials among the most un- likely substances. This material, consisting chiefly of carbon, was used by Indians to tattoo designs on their bodies; it was also employed in textile dyes to sadden yellows, and in fawn and black tones. Thomas Cooper, the chemist who recommended the use of soot, gave this rather extensive explanation of its use: Soot is so far from being a despicable ingredient in dyeing, that when it balls well in handling it, you may be sure it will give out an useful colour. The colours of tapestry borders cannot receive their golden tint without soot. The colour of ozier (willow) and wicker baskets require soot, so do all the landscape colours in tapestry. Although the colour produced from soot is very solid, it must never be used in con- junction with the mineral acids, which degrade it. In a boiler of thirty buckets of water, put from ten to twenty buckets of soot. Boil it for two hours, till the soot no longer rises up on boiling: fill the boiler with water, and let it remain for an hour, that the soot may subside. In this liquor pass the yellow cloth which has been already dyed with three or four pounds of weld to one pound of cloth. The colour is browned in proportion as the cloth is permitted to remain in the liquor; which may be from half an hour to two hours, at a pretty high degree of heat, not boiling . . . (The use of soot is too little known in England and this country; but it is of more use as it seems to me in drabs, olives, and browns, than in yellows) (1815, pp. 170-171). I'icure 9,—Sumach plant (Pomet, 1694). Cooper’s fellow dyers had somewhat different experiences in using this material. One claimed that soot hardened wool, another that it gave ‘‘a disagreeable smell to the stuffs” and that it was better not to make use of it for ‘dyeing stuffs that bear a price,” since all its shades could be achieved by other ingredients which were more lasting and also left the wool with a softer hand. This ingredient therefore was probably seldom used except where other better choices were not available. 52 *SUMACH (chiefly Rhus glabra—smooth or red sumach and R. coriaria—Sicilian sumach) Also spelled sumac (FT.) Even before sumach became important to the earliest American colonists, native American varieties of this shrub were used by a number of American Indian tribes. Among them the Ojibas utilized sumach’s fruits in a cool summertime beverage and drank it warmed and sweetened with maple sugar during the winter months; the Kiowa Indians smoked a mixture of tobacco and dried sumach leaves (Uphof, 1959, p. 312). Until after the mid-19th century American dyers considered it a necessity among their stocks of drugs. Besides being a valuable mordant, it was used as a local dye and also could be collected and processed for trade within and outside the colonies. Mark Catesby, the Englishman who recorded American flora and fauna during the 1720s, noted the presence here of Rhus glabrum and R. virginianum. Thirty years later Peter Kalm mentioned its use as a dye in the Philadelphia area. Irascible Thomas Cooper remarked in 1815: “It grows in Syria, Spain, Portugal, Montpelier; and plentifully in Pennsylvania, where want of population, or want of industry, prevents its being gathered”’ (p. 14). Bronson used the stalks in a yellow, with alum mordant. The shoots and leaves with coloring matter similar to that of nutgalls yielded drab and slate colors on woolens and cotton. Sumach was also used in black dyeing (ISI, ws IWS) The finest imported sumach was prepared for market in the following way: Just before the plants flowered, younger twigs were removed, sun-dried, and beaten to remove leaves and flower panicles. The leaves were then exported or, as happened more frequently, the dye was shipped in powdered form. Dyers had to be wary of the latter, for adulteration with sand, ground branches, and other useless or inferior materials was quite common and difficult to discover. During the second half of the 19th century, O’Neill stated that Sicilian sumach was the most esteemed and brought the highest prices. He described it as having a greenish-yellow color, bitter astringent taste, ““and, when good, a smell reminding of tea, or sometimes of new hay.” At that time the author admitted there were no reliable methods of determining the quantity of sumach’s various components. Research around 1900 revealed that European sumach (R. cortaria) and the native American variety (R. glabra) both contained about 25 percent tannin, along with small amounts of other substances. 53 PART TWO Home Dyeing With Natural Dyes (Revised) PRISMATIC Sa a A ofH -ar ris int Lfcubt Ficure 10.—Color wheel. The first known arrangement of colors in wheel form (Harris, 1766). WORKING WITH COLOR “This art is so useful, and the practice of it is at the same time so enter- taining, that he ventures to say, when once a lady has perfected one colour, she will not rest satisfied till she has acquired a further knowledge of colours in general.” These are the words of William Tucker, author of The Family Dyer and Scourer, published in 1831 (p. v), which perfectly express the purpose of the discussion that follows. Seeing Color Close your eyes for a few seconds. After you open them again you will realize that shutting out all light results in total absence of color. You may conclude then that color perception depends upon the presence of light. This fact was long recognized but not clearly understood until the 17th century when Isaac Newton discovered that the ‘‘white” light of the sun is a mixture of all colors. Newton proved this by allowing a beam of light to pass through a glass prism. As the light, composed of a range of light waves of different lengths, passed from air through the denser medium of the prism its components, the colors of the visible spectrum, traveling at different speeds were refracted or bent at different angles. Since each color had a definite wave length, each was separated out at a slightly different angle, resulting in a fan-shaped series of hues within the prism. Performing this experiment yourself you will see that the colors are arranged in a definite order. Red with the longest wave length is always followed by orange, yellow, green, blue, and indigo. Violet with the shortest wave length is at the opposite end of the visible spectrum from red. It was further learned that red, green, and violet are the basic or primary colors of the visible spectrum. This can be proved by directing beams containing equal amounts of red, green, and violet light to one point on a wall. This combination of the three primaries results in a spot of “white” light. When daylight strikes a colored object such as a red cloth, all the various wave lengths in light except the red ones are absorbed. Thus the eye, focused Dg 285-390—68——5 upon the red cloth, sees the color red because red wave lengths are not absorbed but reflected and perceived by the viewer. Exactly how this sensation is received and transmitted by the human nervous system is not known, although there are a number of theories on this aspect of color perception. The classic theory of the nature of color was more fully inter- preted for the layman by Sargent (1964). Land’s interesting new concept of color vision is also recommended for those who wish to pursue the subject further (1964). The relationship of light to colored objects is of great concern to the dyer to whom a colored textile will appear quite different under varying light conditions. For example, the red of the cloth in question may appear clear and pure in daylight, yellow red in yellowish incandescent light, and bluish red under blued fluorescent lighting. These effects cay be predicted since substances can only reflect rays present in the light that falls on them. We know that daylight, being white light, contains all wave lengths, so all wave lengths except red will be absorbed. Only red will be reflected, thus we will perceive the cloth as pure red. Incandescent light is a weak yellow light; thus the light waves of yellow red will be reflected from the surface of the cloth. The same will be true of the slightly blued fluorescent light which will allow the blue-red light waves to be reflected. If a strong blue-green light almost devoid of red were turned on the red cloth, the object could reflect almost no red and would appear black under the new light. This would explain why two “perfectly matched” colors will appear different under differing light conditions. It also suggests that colors can be modified by clever use of lighting. Mixing Colors Most of the dyer’s everyday problems will concern colored textiles, rather than colored light. Although identifying and describing color is as elusive as trying to describe musical sound, color theorists have succeeded in developing systems which enable dyers to communicate their ideas. The systems vary greatly, but most have in common the notion that all colors possess three qualities: hue, value, intensity. To illustrate this point, you might try painting or dyeing a green swatch, roughly matching a green I am thinking of. If you dye a dark, dull yellowed green it will be incorrect. A dark, bright yellow green will also be incorrect. My green is light, bright and close to blue green. Your next comment would be that you were not supplied with. an adequate description of the particular color requested. This is true because the hue or color name alone did not give us any idea of the value and intensity of this special green. Any color description omitting these two qualities would be too vague to be useful. 58 Value refers to a hue’s lightness or darkness—its nearness to black or white on the value scale (figure 11). Intensity or saturation indicates the purity or brightness of a hue. At one end of the saturation scale a hue is ‘most pure and bright. At the opposite end are the dulled or neutralized hues. Figure 11.—Value chart showing the range of grays between black and white. The first-known use of a wheel arrangement of hues is shown in figure 10. Moses Harris devised this system in about 1766, and since his time many color theorists including Chevreul, Munsell, Ostwald, and others have developed and modified this theme. Red, yellow, and blue are the basic or primary hues on this color wheel, since no mixture of colored pigments will produce either red, yellow, or blue, but mixing varying quantities of the primaries will theoretically produce all other hues. Pairs of primaries make the secondary hues: orange from red and yellow; green from yellow and blue; purple from blue and red. Between the primaries and secondaries on the Harris color wheel are hues which combine a primary with its adjacent secondary. These include red purple, purple red, orange red, red orange, etc., with the second part of the color name indicating the predominating hue. Thus by mixing pigments one can theoretically achieve the following results: Primary Secondary Tertiary 21810 less purple -+ more red = purple red m ae less red + more purple = red purple BLUE less purple -+ more blue = purple blue less blue + more purple = blue purple BLUE less green - more blue = green biue ue Se less blue + more green = blue green YELLOW less green -+ more yellow = green yellow less yellow + more green = yellow green YELLOW less orange + more yellow = orange yellow it wire: less yellow -+- more orange = yellow orange RED less orange -- more red = orange red less red -+- more orange = red orange 5) Because concentrations of dye solutions vary, one must experiment to learn the exact proportions needed to obtain specific colors. For example, one drop of blue in a cup of yellow dye solution could result in a satisfactory green. One drop of the same yellow in a cup of the same blue may not make any noticeable change in the appearance of the blue dye. Thus the above chart is only a guide suggesting which hues may be combined to form new hues or to modify existing ones. The individual who mixes dyes will become acquainted with the infinite range of colors possible once he knows the color wheel and the character of his own dyes or pigments. Of the neutrals, only black is included on Moses Harris’ color wheel. As Harris has indicated, all three primary pigments mixed together will make black. Dyers have known this for centuries; in fact, this combination was used during the 18th and 19th centuries to dye tapestry yarn black at the Gobelins factory in Paris. Dipping wool into a blue vat first, then into a red and a yellow dyebath was very expensive and time-consuming, but the resulting dye was rich and durable. Even more important, yarns dyed black in this way did not require iron mordants that after a few years would corrode the wool fibers. White, another of the neutrals, is the absence of colored pigment and can only be achieved in textiles by bleaching. Bleaching is necessary to provide a clean background when dyeing a pure, light color. Grays are obtained in several ways. Black and white pigments can be mixed together to make gray; additions of white result in light grays, additions of black darken them. Another way of mixing gray is by combining hues directly opposite each other on the color wheel. Each pair of these complementary hues will make an individual gray. For example, mixtures of red and green, orange and blue, and yellow and purple will produce three noticeably different grays. Grays made by combining complements can also be lightened or darkened by addition of white or black. All the hues shown along the outer edge of the color wheel are meant to be at their highest intensity. Because of the age and quality of the colors used by Mr. Harris, several of these hues appear dulled. Let us assume, however, that they are as bright as the hues in the spectrum. How can one of these colored pigments be neutralized? There are two possibilities: black and white can be added; also, addition of the hue’s complement will accomplish the same general effect. Two complements will usually make a “livelier”? gray than will a black plus white combination. Regardless of the neutralizing pigment, if the addition is lighter than the original pigment, it will lighten as well as neutralize. If the addition is darker than the original, its effect will be that of darkening and neutralizing. 60 The above information can only be considered a brief introduction to the subject of color systems. Fuller discussions may be found in Itten, 1961; Minnaert, 1954; Munsell, 1941; and Sargent, 1964. Color Variation in Home-Dyed Textiles Even the most methodical home dyer will find that it is practically impossible to duplicate the colors of textiles dyed with natural dyestuffs. The dye material itself makes variation the rule since so many factors influence the growth and development of vegetable materials. The subject is far too broad to be explored in detail here, however, the causes of color variation in natural dyes are worth mentioning. They include differences in growing conditions, the area in which the plants are grown, climatic conditions, and quality of soil. Different members of plant families may contain varying amounts and qualities of dye principles. Usually the greatest quantity of dye is extracted from plants when they are ready to mature, although timing would differ with each plant. Often flowers can be used fresh or dried, but even the manner in which they are dried could affect the quality of dye extracted. Aside from care in selecting and handling the plants, one key to successful dyeing is a supply of soft water. Writers of early 19th-century dyebooks never failed to mention this point. There are very few dyestuffs that work most effectively in hard water; where hard water is needed, chemicals can be added to harden the water. Although the calcium, magnesium, and iron salts and other minerals which make water hard may not change color radically, they can cause spotting and irregular distribution of dyes in textiles. Since mordants are discussed more fully in a later section, it is only necessary to mention here that the mordant used often affects the hue as well as colorfastness of the dyed textile. A notable illustration is that of cochineal-dyed wool. White wool becomes purple when dyed with cochineal mordanted with chrome. It takes on a red hue when mordanted with a tin compound The same mordants will produce very slight differ- ences in hue or intensity when combined with other dyestuffs. Each dye recipe specifies the mordant needed to obtain stated colors. If you decide to experiment with mordants, remember that the primary purpose of a mordant is to unite dyestuffs to fibers. A beautiful color achieved by combining a dye with an incompatible mordant will result in a color that may fade soon after washing or exposure to sunlight, or it may adversely affect the wool’s texture or wearing qualities. 61 Limited Color Range of Natural Dyes At first glance the range of hues made with natural dyestuffs may seem disappointingly narrow. More than half the dye recipes in this book produce yellows—from light and bright to dark and dull—with the em- phasis on the neutral end of the saturation scale. Beyond these, a few browns, grays, oranges, and reds are included, with one each of purple and blue. Some 18th- and 19th-century textile dyers who were keenly aware of the color limitations of native natural dye materials searched the world for new sources of permanent dyes. Others with little concern for lasting results, and with an eye on profits, lowered their standards of colorfastness to broaden their stock of salable colors by using dyes they knew would fade in sunlight and washing. Most color names listed with the dye recipes are descriptive and should be self-explanatory, e.g., light greenish yellow, dark brown, etc. If they seem general, they are deliberately so, because of the above-mentioned variations inherent in natural dyes. Even though there is seldom a direct reference to saturation in these color names, the purest colors result from using fresh, carefully selected flowers or other plant material and strict adherence to mordanting and dyeing time and temperature requirements. The color names not found in any color chart, such as brass and khaki, can be checked in the ‘‘Dictionary of Color’? by Maerz and Paul. Because the color plates in that book were printed in 1930 and the paper on which they were printed has changed color, these now only roughly approximate the authors’ original color swatches. Flag red, the only color not included in the color dictionary, can be interpreted as a pure red of medium value. Fiber, Yarn, and Piece Dyeing We have just noted the color limitations imposed by natural dyestuffs. Working with textile materials, however, the craftsman has an unusual opportunity to mix colors to achieve unique effects. Top-dyeing (see p. 107), the most obvious way of expanding the range of colors, consists of dipping a textile into several different dyebaths in succession. Thus, dipping a cloth into a blue vat then a yellow dyebath will make green; red and yellow dippings will result in orange, etc. The technique can be applied to any combination of colors, although generally the dyes producing the clearest colors are best for top-dyeing. The way a textile is processed—starting with very fine individual raw fibers, combining these into lengths of yarn, and finally weaving the yarn into sheets of cloth—amakes it possible for the dyer to color textile material while in the fiber, yarn, or cloth stage. Fiber-dyeing, most frequently 62 applied to raw wool, refers to wool that is sheared from the sheep, scoured, and then dyed. If the fibers are then divided among several different colored dyebaths and mixed and carded together, the fine colored fibers will be so thoroughly blended that yarn spun with them will appear solid- colored from a distance. A close-up view will reveal subtle variations in hue. Tweeds are often fiber-dyed or “‘dyed-in-the-wool.”’ Many home dyers color yarns for weaving or knitting into solid-colored textiles; however, yarn dyeing can present other creative opportunities to the imaginative colorist. For example, a textile can appear solid-colored, yet may actually be a blend of two tones alternating in the warp and weft, or two colored strands knitted or woven as one. Another way of achieving this effect is by combining one color in the warp with another color in the weft. These treatments add depth to a “‘solid’”’ hue. Other more traditional uses of yarn-dyed materials are in checks, plaids, stripes, or irregular patterns. Some optical tricks are played by placing controlled amounts of contrasting hues adjacent to each other. Yarns can also be tie-dyed and top-dyed to achieve patterns. Most piece-dyed cloths are dyed as solid colors. However, patterns can be introduced into sheer fabrics by tie-dyeing them or by resist-dyeing techniques such as batik. Since all of these specialized patterning techniques require skills beyond the scope of this book, we recommend that you consult Pellew’s book (1913) for information on ‘Tied and Dyed Work’ and Krevetsky (1964) or Mijer (1920) for a detailed explanation of batik. Finally certain factors outside the dyestuffs and their union with cloth affect the appearance of colored textiles. These include the effect of light on colored materials and the effect that adjacent hues have on each other. Texture, which has not been mentioned previously, greatly influences the distribution of light on the surface of fabrics. Folding a fabric emphasizes its textural qualities. For example, light playing on a sleek red satin causes it to appear much lighter than a thick, rough tweed having the same red hue. Drape the satin, and there will be a distinct difference in value between the outermost and innermost parts of the folds. These effects can be ex- ploited only when they are thoroughly understood. Thus the home dyer who develops a sensitive eye, understanding of color, and an experimental attitude will derive the greatest enjoyment from working with this challenging color medium. 63 PLANNING A HOME DYEING PROJECT The revision of Home dyeing with natural dyes presented here reports the results of tests on about 65 natural materials used for dyeing cotton and wool cloth. Most of the dyes studied are of vegetable origin. In fact the terms “natural” and ‘vegetable’? dyes are often used interchangeably though a few, such as cochineal, are of animal origin, and iron buff and others are developed from mineral pigments. Samples of all the dyes used in these experiments were given standard tests for colorfastness. Many were discarded as unsatisfactory, and recipes are included only for those that produced attractive colors fast to both light and washing. Since the common names of trees and plants differ from place to place, the scientific names are given. The college of agriculture in any state will help in identifying plant materials. In each locality there are many natural dye materials that by one dye method or another will give satisfactory colors. This publication is intended merely as a guide for such work. Colorfastness A dyer writing ca. 1830 remarked: “‘As to garments whose colours are changed every year, if the colour preserves its full brightness during the season, it is as much as can be required... .”” Most contemporary craftsmen have neither the time nor inclination to exert the effort required to dye textiles unless they can be reasonably sure that their efforts will not be lost within a short time; thus the fastness or permanence of a dye is an important consideration. While fastness is of great concern, the home dyer should be aware that no dye is absolutely fast under all conditions. It may be fast to light, or to perspiration, or to washing, but seldom fast under all three conditions. Futhermore, a dye may be fast on one fiber and not on another; or 1t may be fast when dyed by one method and not another. Of all the textile fibers, wool can be dyed most easily, and the resulting colors change the least. Cotton does not combine easily with dyes, and fast colors are produced on it only by complicated processes. The need for a particular kind of fastness depends on the nature of the color change and the use to be made of the dyed fabric. For example, a fabric dyed brown with tree bark may darken on exposure to light. While this color change might be satisfactory in a hooked rug, it would be un- acceptable in window draperies. To make sure that these recipes produce colors permanent enough to be useful for most purposes, the dyed fabrics were tested for their fastness to light and washing. The results are included in the dye recipes. 64 For the light test, samples of the dyed fabrics were cut and exposed for 40 hours to the rays of a carbon-arc lamp. Throughout the test period half of each piece was shielded while the rays of the lamp shone directly on the other half. Then the two parts were compared and the fastness to light rated as follows: Good—no appreciable change of color; fair—appreciable but not objectionable change of color; poor—objectionable change of color. Though these light tests were run in a standard fading apparatus, the same method can be followed at home by exposing samples to sunlight. Cut 2-inch-square openings in each of two pieces of heavy cardboard, fasten a swatch of dyed cloth to one piece of cardboard and lay the other cardboard over the swatch, sandwich fashion. It is important that the light come through the fabric. Then place this sample in its frame out of doors in the direct sunlight and tilted toward the sun. After a few days remove and compare the section exposed to the sun with the covered portion. This test cannot be considered absolutely conclusive, since the exposure, strength of sunlight at the particular season, and other factors modify results. Such a test will, however, suggest whether a dyed fabric may be satisfactory as a curtain or decorative fabric that would be exposed to sunlight. To determine whether a dye will bleed, stain or fade in washing, samples were prepared by sewing a 2’’ x 4’” piece of dyed fabric to a similar piece of undyed material. Each sample was placed in a half-pint jar partly filled with neutral soap solution (0.5 percent for wool and 0.1 percent for cotton) at 120° F. and agitated in a shaking machine for 30 minutes. The sample was removed, squeezed through a wringer, and rinsed by agitating in water for 10 minutes. Rinsing was repeated five times and the temperature of each rinse gradually dropped to lukewarm. The samples were dried quickly, then compared with the original unwashed fabric, and rated as in the light test. A similar test could be devised for wash testing under home washing conditions. Equipment and Supplies Simple equipment and a few easily obtainable supplies are needed to dye textile materials at home. These include: Scales that will weight accurately in fractions of an ounce. Kettles of enamel or copper, large enough to immerse the material completely. Because iron darkens colors and tin makes colors harsh, kettles made of these materials should be avoided if possible. Large pails or tubs for rinsing dyed materials. Measuring equipment: gallon, peck, and quart measures, tablespoons and dippers. 65 Cheesecloth for straining dye liquor. Sticks or glass rods for stirring and turning material in the dyebath. These should be made of smooth, splinter-free wood or very thick glass. Glass towel rods are useful. Most plastics melt or bend when subjected to high temperatures, thus most plastic rods could not be used. Stove: if possible, have it set lower than usual so that lifting pots of water and stirring the dyebath will be easier. Thermometer for testing temperature of the dyebath and rinse water. Rubber gloves for protecting the hands from chemicals used in dyeing. Drying rack or clothesline sheltered from the sun. Soft water supply: filtered rain water or chemically softened water will help to prevent spotting caused by minerals in water. Neutral soap: mild soap such as recommended for lingerie and fine woolens is satisfactory. Dye materials and chemicals which cannot be found in nature may be purchased from drugstores and botanical-drug suppliers. See appendix A for list of common names of dye chemicals. Preparation for Dyeing A NOTE OF CAUTION: Keep dye material out of children’s reach. Some of these substances are poisonous, and may cause skin irritation. 1. Collecting and storing plant materials It is difficult to make general statements on this subject beyond an old-time dyer’s warning: ‘‘In collecting die-stuffs, be particular to get the best kind of every sort; for in having one (specimen) that is poor, it may be a great injury to the color . . .” (Waite, 1815, p. 80). The most concentrated dyes are usually found in material that is harvested just as it is reaching maturity. Often it is used immediately; in certain cases, the plant material can be spread out and dried carefully, avoiding the danger of mold caused by trapping plant moisture. 2. Weighing The dry weight of the fiber, yarn, or cloth to be dyed determines the quantity of soap to use in washing it before dyeing; it also determines the quantity of chemicals and dyestuffs to use in the mordanting and dye- ing processes. All recipes are based on 1 pound of wool or cotton weighed dry before mordanting. 3. Washing Dye solutions penetrate textile materials more thoroughly and evenly if the yarn or fabric to be dyed is washed in soap and water and well rinsed before dyeing. Starch and sizing which prevent fibers from readily 66 absorbing dyestuffs should be removed by washing. Spots and stains cause uneven dyeing and should also be removed before washing. 4. Washing Wool Before dyeing wool, use the following washing procedure. Dissolve neutral soap in 5 gallons of lukewarm (95° F.), soft water. Wash the ma- terial thoroughly and squeeze out suds. Repeat the washing procedure. After the second washing squeeze out the suds, rinse the material three or four times, or until all traces of soap have been rinsed away. Felting and shrinkage can be avoided if wool is handled quickly and gently throughout the washing and dyeing processes. Always squeeze excess moisture out of materials. Never wring or twist wool. Alsc, since sudden temperature changes will cause wool to shrink and become harsh, the following measures should be taken to avoid these conditions. First, keep the temperature of the material as even as possible by transferring it directly from suds to rinses without delay; second, keep the water at a lukewarm temperature for all suds and rinses. If unspun wool is to be used for dyeing, the raw wool must be thoroughly scoured and cleaned first. The natural wax and grease in raw wool tend to make the fiber water repellent, thus the dye solution cannot penetrate. After scouring (Davenport, 1964, p. 117) and dyeing, wool is carded and spun into yarn. When wool from different dye lots is blended together in carding, interesting tweed color effects can be achieved. 5. Washing Cotton Before dyeing cotton, use the following washing procedure. Dissolve neutral soap in 5 gallons of hot (140° F.), soft water. Wash the material thoroughly and squeeze out suds. Repeat the washing procedure, then rinse. The second rinse water should be hotter than the first one, and the material should be allowed to soak in it for at least a half hour. This should be followed by two or three cooler rinses. Mordants Many natural dyes will fade and “‘bleed”’ badly unless the yarn or fabric is first treated with a chemical called a mordant, a metallic salt that helps to fix the color to the fiber. The mordants commonly used with the natural dyestuffs are alum (aluminum potassium sulfate), chrome (potassium dichromate), copperas (ferrous sulfate), and tannic acid or some other source of tannin such as oak galls or sumach leaves. Commercial dyers use oils and other substances too difficult for the home dyer to apply. By using different mordants, a variety of shades and sometimes even different colors may be obtained from a single dyestuff. For example, on wool, dahlia flowers used with a chrome mordant give an orange color 67 and with alum, a light yellow. Cochineal mordanted with alum gives a red and with chrome, a purple. Both wool and silk have the property of holding chemicals in their fibers. For example, when wool is boiled in a solution of potassium dichromate (chrome mordant) a certain amount of chromium oxide is held in the fiber, and the dyestuff then combines with this mordanted wool to form a perma- nent color. Cotton and the other vegetable fibers do not absorb mordants as readily as wool. Vegetable fibers, however, combine well with tannic acid, which is used either as a mordant or as an agent for fixing mordants in the fiber. Mordanting Wool Alum Mordant For | pound of dry wool, use 4 ounces potash alum (aluminum potassium sulfate) 1 ounce cream of tartar Dissolve the alum and cream of tartar in 4 to 4% gallons of cold soft water. Immerse the wool after first wetting it thoroughly and squeezing out excess moisture. Gradually heat the mordant bath to boiling; boil it gently for 1 hour. While the wool is in the solution, it should be turned and stirred to insure complete penetration of the mordant. As liquid boils away, add more water to maintain the original level of the bath. Allow the wool to stand overnight in the mordant. The following morning squeeze out excess moisture, roll the wool in a dry towel, and store it in a cool place. Rinse the mordanted material well just before immersing it in the dyebath. Chrome Mordant For 1 pound of dry wool, use 15 ounce potassium dichromate Dissolve the potassium dichromate in 4 to 44 gallons of cold soft water and follow directions for mordanting wool with alum. Mordanting Cotton Alum Mordant For 1 pound of dry cotton, use 4 ounces potash alum (aluminum potassium sulfate) 1 ounce washing soda (sodium carbonate ) Dissolve the alum and washing soda in 4 to 445 gallons of cold water. Immerse the cotton, after first wetting it thoroughly in clear water and squeezing out excess moisture. Stir while gradually heating to boiling, then boil for 1 hour. Allow the yarn to remain in the bath overnight. The follow- 68 ing morning remove the cotton from the mordant solution, squeeze out excess moisture, roll the material in a dry towel and store it in a cool place. Rinse the mordanted cotton well before immersing it in the dyebath. Alum-T annin-Alum Mordant (process takes two days) For one pound of dry cotton, use 8 ounces potash alum (aluminum potassium sulfate) 2 ounces sodium carbonate 10 ounces powdered oak galls, or one ounce tannic acid, or extract from 4 to 6 ounces dry sumach leaves Dissolve half of the alum (4 oz.) and half of the washing soda (1 oz.) in 4 to 4% gallons of cold soft water. Immerse the cotton, after first wetting it thoroughly and squeezing out excess moisture. Stir while gradually heat- ing to boiling, then boil for one hour. Allow the material to remain in the bath overnight.* The following morning squeeze excess moisture from the material, rinse and put it into a bath of oak galls, tannic acid, or sumach leaves heated to 140° to 160° F. Work the yarn in this bath for one hour and allow it to stay in the bath overnight. The following day rinse it briefly. Then dissolve the remainder of the alum and washing soda in 4 to 4% gallons of water and repeat the mordanting process to* above. The follow- ing morning squeeze excess moisture out of the cotton and rinse thoroughly just before dyeing. To prepare the extract of sumach leaves, soak the dry leaves in water for half an hour, boil them for 30 minutes, strain the liquid, and allow the bath to cool to 140° to 160° F. DYE RECIPES General Instructions Dye recipes are arranged alphabetically by the name of the flower, bark, or other dye material. The heading “barks” includes directions for the four basic methods of dyeing with tree barks and is followed by an alpha- betical listing of many tree barks that were tested; special information about dyeing with these barks is found in this listing. Read complete instructions for mordanting and dyeing before undertaking any project. It is also helpful to assemble all chemicals, dye materials, and equipment before starting the dyeing process. All dyebaths require a plentiful supply of soft water—at least 4 to 4% gallons for each pound of yarn or cloth dyed. Crowding textiles or using water that contains certain mineral deposits may result in streaked or spotted colors. 69 Although there are specific instructions for extracting dyes from each type of plant or animal material listed, certain general procedures apply to all dyeing: ie When textile materials are immersed in mordanting and dye liquors they should be opened out and turned over gently in the liquid from time to time to allow maximum, even penetration of the dye or mordant. This process is sometimes referred to as ‘“‘working”’ the material. Sudden temperature changes should be avoided in all stages of dyeing and mordanting, particularly when handling wool. Tempera- ture of the dyebath should be lukewarm (95° F.) for wool; hot (140° F.) for cotton. Dyebaths are then heated gradually to boiling and simmered or boiled according to the specific recipe. . If the dye liquid boils down, lift out the fibers, yarn, or cloth and add boiling water, thus keeping the water level of the dyebath constant throughout the dye process. After dyeing, the first rinse water should be the same temperature as the dyebath. Temperature can be cooled gradually until finally arriving at the last cool, clear rinse water. Insufficient rinsing often causes dye to rub off or crock later. . When squeezing excess moisture from materials after mordanting, dyeing or rinsing, do not twist or wring the wool or cotton. Such harsh treatment introduces streaks and wrinkles that are difficult to remove. . After the final rinse, roll the dyed material in a clean cloth or towel to absorb excess moisture; then shake it well and hang it in the shade to dry. Do not dry wool in a clothes drier. When dyed fabric is dry enough to iron, cover it with a cloth and steam press. Fibers and yarn are ready for use after they are dried. . The full amount of yarn or cloth required for each project should be dyed at one time. Vegetable dye materials vary so much that it is impossible to duplicate colors exactly. To lighten or darken colors, decrease or increase the quantity of dyestuffs. Experimentation will result in interesting color effects. These recipes provide basic information on dyeing with natural ingredients and should be regarded as a first step in the exploration of natural dye materials. Many other good dyestuffs are available locally to craftsmen who wish to experiment. The following plant materials, sometimes suggested for dyeing, do not produce fast colors on wool or cotton, therefore they were not included in the dye recipes: annatto seeds; Japanese barberry root; beets; crab-apple 70 peelings; the fruit of the blackberry, blueberry, cranberry, and pokeweed; purple iris flowers; mosses; peach leaves; red roses; sumach leaves; turmeric and willow leaves. VESTED) DYE RECIPES ASTER, CHINESE (Callistemma chinensis) The coloring principles callistephin and asterin are found in asters, especially in deep purple-red flowers. The asters used in testing this recipe were rose pink. Light Greenish-Yellow Wool: chrome mordant Colorfastness: good 1 pound of wool 16 bushel fresh aster flowers Use chrome mordant (see pages 67 to 68). Cut the flowers into small pieces, cover with water and boil for 10 minutes. Strain out the flowers, then add water to make a dyebath of 4 to 4% gallons. Before immersing the mordanted wool in the dyebath, rinse it and squeeze out excess moisture. Immerse wool; heat the dyebath to boiling; boil gently for 20 minutes, rinse and dry. BARKS The barks of many trees are good sources of brown dyes. A wide range of tones from the very lightest tan to deepest brown can be extracted from the inner bark of such common trees as oak and maple. Wool can be dyed in the complete range of tones, while only lighter browns can be produced in cotton. Most barks are best collected in the fall or winter, but resinous ones may be gathered in the spring. The inner bark can be used either fresh or dried: fresh barks are usually most potent. If barks are stored, they should be dried carefully first, then put in a place free from dampness and mold. The coloring principles of these dyes are combined with a type of tarinin; because of the presence of tannin, fabrics dyed with bark extracts often do not retain their original color, becoming darker brown upon exposure to light. This change can be prevented by treating dyed materials with certain chemicals that fix or remove excess tannin such as potassium dichromate, ferrous sulfate, and copper sulfate which are used in dye methods 2, 3, and 4 on the following pages. Many other barks not included here will produce fast colors in textiles. Experimentation with local materials and application of basic methods of extracting dyes from tree barks can result in attractive and durable colors. 7\ Bark: Dye Method 1 1 pound of wool or cotton 1 peck finely chopped bark Use alum or chrome mordant on wool, and alum or alum-tannin-alum on cotton (see pages 67 to 69). Soak the bark overnight in 2 to 244 gallons of soft water. The following morning gradually heat this bath to boiling, boil for 2 hours. Add hot water as necessary to maintain the original water level. Strain the dye liquid twice through cheesecloth, then add cold water to make a dyebath of 4 to 4 gallons. When the bath is cooled to lukewarm (95° F.), immerse the material after first wetting it thoroughly and squeez- ing out excess moisture. Heat the dyebath to boiling; boil for 30 minutes, rinse and dry. Bark: Dye Method 2 1 pound of wool or cotton 1 peck finely chopped bark 14 ounce potassium dichromate 14 ounce acetic acid, or 6 to 7 tablespoons vinegar Use alum mordant on wool, and alum or alum-tannin-alum on cotton (see pages 67 to 69).

BROOMSEDGE (Andropogon virginicus) Broomsedge or ‘‘dyer’s broom’? grows on open waste ground from Massachusetts to Illinois and south to Florida and Texas. The entire stalk and leaves are used for dyeing. Although it can be gathered at any season for use as a dye, the dye is most concentrated in the summer when the plant is green. It can be cut in June and July, dried, then used as needed. 78 Broomsedge is used in top-dyeing (see pages 107 to 109). Greens are obtained by dipping the material first in a broomsedge dyebath, then in the indigo vat. Henna and brick colors are produced by dipping materials in successive dyebaths of broomsedge and madder. ; Light Greenish-Yellow Wool: alum mordant Colorfastness: good 1 pound wool 34 peck dry broomsedge 1 ounce copper sulfate 16 ounce acetic acid, or 6 to 7 tablespoons vinegar Use alum mordant (see pages 67 to 68).

Boil 10 minutes, rinse and dry. GOLDENROD FLOWERS (Solidago sp.) Goldenrod that grows wild in fields and along roadsides is one native American plant recognized early as a source of yellow dye. With indigo, 86 goldenrod can be top-dyed (see pages 107 to 109) to make dark green shades; top-dyeing goldenrod with madder results in terra cotta and rose- brown tones. Goldenrod does not produce lightfast colors on cotton. Flowers should be picked as they are coming into bloom. They can be used fresh or dried. Brass Wool: chrome mordant Colorfastness: good 1 pound wool 1 to 144 pecks goldenrod flowers Use chrome mordant (see pages 67 to 68). Cover the flowers with water and boil for 15 minutes. Strain out the flowers, then add cold water to make a dyebath of 4 to 444 gallons. Before immersing mordanted material in the dyebath, thoroughly wet it and squeeze out excess moisture. Immerse the wool; heat to boiling; boil for 20 minutes, rinse and dry.

Without rinsing, transfer the material into a boiling bath of potassium dichromate and acetic acid. Stir and boil 10 minutes longer, rinse and dry. Inpico (Indigofera sp.) Indigo was America’s most important dyestuff during the 18th and 19th centuries. Although dyeing with indigo requires both time and patience, the blue shades it produces are very fast to light and washing on both wool and cotton. Indigo does not require a mordant. It belongs to the class of dyestuffs known as vat dyes—so-called because they are applied in a special dyebath called a vat. The following is a simplified explanation of what takes place in the indigo dye vat: 88 All natural dyestuffs must be dissolved in a liquid before textile materials can absorb them. Since water will not dissolve indigo, it must be dissolved in another liquid. When indigo is combined with a reducing agent, a compound is formed that will dissolve in an alkaline liquid. This process turns the indigo dye liquid yellow. When wool and cotton are dipped into this dyebath (known as the indigo, vat) they readily absorb the dye in this yellow, reduced form. The dye is fixed on the fibers permanently by oxidation when the dyed material is exposed to air. During this final step the blue color returns and the dye reverts to its original insoluble form on the fibers. Repeated dipping and airing of the material results in a gradual build-up of blue color on the yarn or fabric; thus the skillful dyer can obtain almost any depth of the blue desired. Both methods of indigo dyeing given below can be used by the home dyer. Method 1: Indigo Fermentation Vat or Blue-Pot The fermentation vat or blue-pot is the oldest method of dyeing with indigo. Bacteria that develop in the vat act as the reducing agent. Al- though dyeing by this method is somewhat complicated, repeated dippings result in a good, fast, dark blue on both wool and cotton if the vat is properly prepared. When top-dyeing (see pages 107 to 109) wool with yellow dyes, mordant (see pages 67 to 69) the material with alum either before or after dyeing. Although treatment before blue-dyeing is not essential, the following methods are sometimes used: For 1 pound of wool: alum mordanting (see pages 67 to 68) or soaking for 30 minutes in a solution of % ounce of washing soda in 4 gallons of luke- warm water. Rinse thoroughly before dyeing. For 1 pound of cotton: alum mordanting (see pages 67 to 68) or boiling the material for 30 minutes in a solution of % ounce of sodium hydroxide in 4 gallons of water. Rinse cotton thoroughly before dyeing. For each pound of wool or cotton, allow: 8 ounces finely powdered indigo 4 ounces wheat bran 4 ounces madder 1144 pounds sodium carbonate (washing soda) 4 gallons water Mix ingredients in a large vessel and keep it at about 85° F. for 5 to 10 days. This blue-pot should be stirred well each morning. When the mixture 89 develops a disagreeable odor, a bluish-coppery scum on top and green streaks throughout, it is ready to be used. Wet the wool or cotton thoroughly before dipping it in the dye vat. Throughout the dyeing process the vat should be kept lukewarm (95° F.) and the material turned and stirred occasionally to assure even absorption of dye. The material must also be lifted out and exposed to the air at intervals during the dye process. Though greenish yellow in the dye liquid, the material will turn blue when exposed to the air. Continue dipping and airing for 30 minutes, then lift the material from the dyebath, squeeze out excess liquid and allow it to air for half an hour. Since depth of color depends on the number of times the material is lifted out and aired, repeat these steps as many times as necessary, increasing each immersion time, until the desired depth of color is achieved. After the last airing the material should be rinsed in lukewarm water and dried. Norte: If the sediment in the bottom of the vat is disturbed the material will be streaked and unevenly dyed. If the dyebath is stirred too much it will turn blue, and thus lose its effectiveness. If this should happen, renew the vat by adding more indigo, bran, madder, and sodium carbonate. Allow it to stand undisturbed for one or two days and it will again be ready for use. In this manner the blue-pot can be replenished and reused many times. Method 2: Indigo Hydrosulfite Vat The hydrosulfite vat is the most easily regulated of the indigo vats and is used extensively among indigo dyers. Both wool and cotton can be dyed in the hydrosulfite vat without mordants. When _ top-dyeing, however, the material should be mordanted with alum either before or after dyeing with indigo, depending on the nature of the other dyestuff. The following quantities are sufficient for dyeing 1 pound of wool or cotton. First make up the following two stock solutions: (A) Indigo Hydrosulfite Solution 414 ounces powdered indigo 3 ounces sodium hydroxide 234 ounces sodium hydrosulfite Mix the powdered indigo with sodium hydroxide which has been dis- solved in water, add enough water to make | gallon of solution; then heat it to 120° F. Stir well while slowly adding the sodium hydrosulfite. Allow the solution to stand for 30 minutes. The liquid should be clear and yellow. A drop running along a glass plate should turn blue in about 25 seconds. Measure out 2 to 24 quarts of solution for the dye vat. Store extra solution in a stoppered bottle. 90 (B) Sodium Hydrosulfite Solution Slowly add: 44 ounce sodium hydrosulfite to 1 quart of water Measure out ¥ to % cup for the dye solution. Keep the extra solution in a stoppered bottle. The dye vat is made up as follows: Heat 4 gallons of water to 120° F. Add % to % cup of sodium hydrosulfite solution (B), stir well and set aside for 10 minutes. Add 2 to 2% quarts of indigo hydrosulfite solution (A). Stir gently and set aside for 20 minutes. When the dye liquor is a clear, yellow liquid it is ready for the textile material. First wet the cloth thoroughly and dip it in the dye vat. Stir it occasionally during the 30 minutes it is in the vat, making certain that the material is always well covered with dye. Without rinsing or squeezing out excess moisture, hang it outside the dye vat. After exposing the material to the air for 30 minutes, dip it in the vat for another 30 minutes. Repeat dipping and airing until the desired color is obtained. After the last airing the material should be rinsed thoroughly in clear water, washed in soapsuds, and rinsed again. If the liquid in the vat turns blue, add more sodium hydrosulfite solution (B), stir the liquid in the vat carefully and allow it to stand for 15 minutes before proceeding with the dye process. If repeated dippings and airings fail to produce a noticeably darker blue in the material, the dye vat needs more indigo hydrosulfite solution (A). After renewing the dye vat, proceed as before. IRON BUFF Buff Cotton: no mordant before dyeing Colorfastness: fair 1 pound unmordanted cotton 6 ounces ferrous sulfate (copperas) 6 ounces powdered soap Dissolve the ferrous sulfate in 4 to 4% gallons of water. Before immersing the cotton, thoroughly wet it and squeeze out excess moisture. Stir for a few minutes, remove from dyebath and drain. Dip the material into soap- suds, stir and wring out. Repeat these steps three times, rinse and dry. JUNIPER BERRIES (Juniperus sp.) Juniper, also called red cedar, grows in many sections of the United States. The bark, berries, and twigs are suitable for dyeing purposes. Juniper berries will not dye cotton. 91 Khaki Wool: no mordant before dyeing Colorfastness: good 1 pound wool 2 quarts ripe juniper berries 2 ounces potash alum 34 ounce ammonium chloride 1 ounce cream of tartar 1 ounce copper sulfate 1 ounce copper acetate Dissolve the alum, ammonium chloride, cream of tartar, and copper sulfate in 4 to 44 gallons of water. Before immersing the wool in the dyebath, thoroughly wet it and squeeze out excess moisture. Heat it to boiling; boil for 1 hour. Allow the material to stand in this mordant liquor until it is cool, then rinse the wool, roll it in a towel and set it aside. Break up the berries, tie them in a cheesecloth bag, and place the bag in enough water to cover it. Allow the berries to soak overnight. The follow- ing morning boil the berries for 1 hour. After removing the cheesecloth bag from the dye extract, add cold water to make a dyebath of 4 to 4% gallons. Thoroughly wet the previously mordanted wool in water, squeeze out excess moisture and immerse the material in the dyebath. Heat the dyebath to boiling, continue to boil for 1 to 2 hours, then remove the wool. Next dissolve copper acetate in the dye liquor, return the wool material to it and boil it for 15 to 30 minutes longer, rinse and dry. LICHENS For many years rural dyers of Sweden, Scotland, and Ireland have used lichens for coloring woolens various shades of brown, yellow, red, and purple. Though lichens were never used as frequently as other dye materials in the United States, many produce interesting colors without mordants. The two recipes which follow merely suggest the possibilities that might be explored with lichen dyeing. A more complete study of this subject is Eileen M. Bolton’s book “‘Lichens for Vegetable Dyeing’? which gives details on identification of lichens and directions for using them. LicHEN | (Peltigera sp.) Lichens of the genus Peltigera are flat and leaflike. The lobes are large, sometimes overlapping, and are dark greenish brown when wet, but turn ashen when dried (Bolton, 1957). They grow on soil and mosses in damp woods and are abundant in all parts of North America, especially in the mountains of the South. 92 Yetlow-Tan Wool: alum mordant Colorfastness: fair to light, good to washing 1 pound wool 1 peck crushed dry lichens Use alum mordant (see pages 67 to 68). Cover the lichens with water and soak them overnight. The following morning heat the water to boil- ing, and boil for 1 hour.

Dark Greenish-Yellow Wool: chrome mordant Colorfastness: good 1 pound wool 34 peck of fresh zinnia petals and flower heads Follow the directions for dyeing “Light Yellow Wool” (above). 106 TOP-DYEING It is often necessary to top-dye or dip material into two differently colored dyebaths in order to obtain a desired hue. See the section on Color (pages 57 - to 63) for suggestions on combining colors. To top-dye successfully one must start with dyebaths that will produce good clear colors. Thus, if a good green is desired, start with a bright clear yellow (not a muddy yellow or yellow tan), then top it with a clear blue. Yellows obtained from broomsedge, fustic extract, privet leaves, or golden- rod flowers are satisfactory, but prolonged boiling of any of these is likely to dull the color. Good greens are also obtained by dyeing first with indigo and top-dyeing with yellow. The chart below suggests which dyestuffs yielding yellow, red, brown, and blue can be combined to produce fast green, orange, red purple, and black.
