Tartaric acid is a white crystalline organic acid. It can be used to adjust the pH of the dye pot for dyes that have an affinity for acids.
Tartaric Acid is a non-toxic discharge choice, and may be applied in solution or in combination with gum tragacanth. Use a brush to apply, or stamps, silkscreen or thermal image screen, among other design choices.
In the dye pot, follow the general recipe for adding Tartaric Acid, We suggest it be added l teaspoon at a time, dissolved, into the dyebath until you are satisfied with the color. (Remember always add acid into water, never water into acid.)
