Dharma Acid Dyes are concentrated powdered dyes for dyeing protein fibers and some Nylons (best for PFP or "prepared for printing" Nylon). The best choice for tub dyeing silk and wool fabrics, skeins of silk or wool yarn, feathers, etc. You can also paint or print with with it if you fix it by steaming. For tub dyeing, use these dyes on your stove or in a washing machine, keeping in mind that they do require very HOT water or steaming for best results. The only other thing needed is white vinegar for the fixative, or citric acid which is odorless. Acid Dyes react fast, exhaust well, and results for most colors are very lightfast and washfast. As with all powdered dyes or craft chemicals, handle with care and use good housekeeping procedures. Our color charts were done from wool dyeings, in a pot, on the stove. Silk and wool do not always come out the same color, techniques and water cause variation, plus monitors vary, etc., so when color is critical, test, test, test! Wash items dyed with acid dye in cold water.
Keep in mind that an * by the name of a dye color (blacks and navy) indicates to use that color at 4% of weight of goods rather than 1.5 - 2% for the rest of the colors.
