Cream of Tartar


Cream of Tartar

Cream of Tartar, also known as potassium bitartrate, is produced by fermenting grape juice. It is used to acidify the dye bath to effect a color change, and in mordanting to soften wool fibers as well as slow down the mordant uptake in a hot mordant bath.

This listing is for 100 grams of cream of tartar.
