Infusions are water soluble particles with 2 parts.
The dye colour pigments are mixed with Walnut stain.
They are suitable for paper and fabric ( heat set)
The colour powder particles dissolve faster than the walnut crystals, so you can control how much colour-to-brown stain ratio you get by:
1. the amount of water you apply, and
2. when you apply water (before or after sprinkling the powders) and
3. how soon you dry the wet paper or fabric after applying water.
