A water-reactive dry dye stain is suitable for fabric and paper. Our two-part formulation has 2 different crystals that react with the water at 2 different rates; the color particles act fast, and the brown walnut crystals slowly dissolve. This allows control over how much brown-to-color you create depending on how much water you apply and when you dry.
Make the product permanent by using glazes instead of water or add gum arabic to the mix as another 'binding' option.
Sold in small bottles with aluminum caps, approx. 15ml. To dispense, poke a hole in the cap and sprinkle in the concentration of your preference.
