For professional silk painters who steam set, liquid acid dyes provide the brightest, most intense colors. To make your own liquid acid dyes for silk painting, use the following recipe:
- Stock Solution
- Add 8 oz. (1 cup) of very hot water to one .5 oz. jar of Jacquard Acid Dye powder.
- Stir until dissolved. This will yield a very concentrated dye stock solution. Most colors require further dilution. Note: Every color has a different solubility. Some colors are difficult to dissolve, but most are easily dissolved. A small amount of alcohol (about 1 tablespoon) can be added to the dye solution as a wetting agent.
- The final concentration of the dye solution for painting should be between 4 and 8%. Start by adding 4 oz. (1/2 cup) of water to the 8 ounces of stock solution you have, test the color and continue adding water until desired shade is achieved.
Keep in mind that the color intensity really develops in the steam setting process. Most colors will remain stable in solution for a long period of time. However, some colors will fall out of solution upon cooling or from sitting for a matter of weeks. To restore them simply heat them on the stove.
