“Persian Scarlet. Take lac colour, and if you choose a little cochineal for richness, and soak from four to six days; strain it in two cloths and add alum and a little turmeric; let it stand for three hours. Put wool in and steep for twenty-four hours, then boil for two hours. Take out the wool and add mineral acid; re-enter wool and boil an hour more. Wash fifteen minutes when cold, and dry in the shade.
“Saffron Yellow. Take turmeric, cinnabar, and soda, add water and keep for a full day. Then add some alum, make the dip, and soak the wool for thirty hours. Cook it for several hours, and dry in the shade after beating and good washing.
“Rich Yellow. Take asburg and turmeric, soak for a night in water, steep the wool for twenty-four hours, add alum, shake out, and dry in shade.”
Identical shades of a number of colours are not produced in all parts of the Orient, not only for the reason that soil, moisture, and climate affect the colour values of dye-stuff, but because each family of dyers preserve inviolable the craft secrets transmitted from their forefathers. Thus it happens that different parts of the rug-producing countries adhere to particular tones that help to identify the locality where the fabrics were woven.
Unfortunately the Western aniline dyes, which were introduced about the year 1860 and quickly adopted because they are cheaper and less complicated in their application, have to such an extent transplanted some of these fine old vegetable dyes that a number of the richest and most delicate colours found in the rugs of a former century are no longer produced. Thus the superb blue of the fine old Ispahans, as well as of lustre tiles and illuminated manuscripts, belongs to a lost art. The disadvantages of the aniline dyes are several: they have a tendency to make the fibres of the textile fabric brittle, and when it is wet the colours will frequently run. Some dyes also fade more readily than others, so that if a colour be the product of two or more dyes, the resultant tint may be totally unlike the original. On the other hand, not all vegetable dyes are fast; but as they fade they mellow into more pleasing shades. Efforts have been made to encourage the use of old vegetable dyes; but unless the laws which have been enacted in parts of Asia to restrict the importation of aniline dyes be more stringently enforced than in the past, the cultivation in the garden patch of the dye-producing herbs and plants will soon cease to be the time-honoured occupation it was in days gone by.
Almost as important as the art of preparing the dyes is that of properly applying them to the yarns. It is an art that demands infinite pains in its technique, as well as a lifetime to acquire. It is in itself a separate profession practised by artisans who guard with jealousy the sacred secrets that transmitted from generation to generation occupy their thoughts to the exclusion of almost everything else. The homes of these professional dyers in the larger villages and cities are located on a stream of water which possesses mineral properties that long experience has proven especially suitable as solvents for the different kinds of colouring matter. Ranged about the walls of their low dwellings are jars or vats containing liquid dye of various colours. Suspended above them, from hooks driven into beams, are the yarns from which, after immersion in the proper vats, the liquids are allowed to drain. After this the yarns are exposed for the proper length of time to the dry air and burning sun. It is, therefore, the suitable mordants, the preparation of the proper dyes for the vats, the immersion of the yarn in correct sequence and for the correct length of time, as well as the exposure to the glare and heat of the sun for a definite period to be gauged to the exact moment, on which the colour results depend. This complicated process by which, for instance, the infinitely different shades of a red, a blue, or a brown may be conveyed to yarn by using the same dyes but by slightly modifying the steps requires the greatest precision, for which no rule but an experience amounting almost to instinct is the guide.

There was a time when the Oriental had not learned the meaning of tempus fugit or seen the glitter of Western gold, when his dyeing and weaving were proud callings, in which entered his deepest feelings. Then the old vegetable dyes that mellow, grow softer and more lustrous, were almost exclusively used; but now throughout all weaving countries the dyer has deteriorated so that he can no longer produce some of the rich colours in use half a century ago. Yet remote from the principal lines of travel, on the edges of the desert, in lonely valleys, among rugged mountains, half-tamed tribes are still dyeing their hand-spun yarn as did their fathers’ fathers.
