Cream of Tartar

Cream of Tartar is the sediment produced in the process of making wine. It is an optional addition to the alum mordant bath and to some dye baths. It is used to soften wool, brighten shades, and point the color of some dyes – such as the fuchsia of cochineal to a true red. Cream of tartar works best with animal or protein fibers and is seldom used with plant or cellulose fibers. Use at 5-6% WOF
