A soft, slippery stone quarried in small chunks and used to reduce friction and absorb moisture. Fullers dust talc on cloth during the fulling mill to ease working; tanners add it to hides to separate the skin from the hair; metalworkers use it as a release agent in casting molds. The rough lump is inexpensive and widely traded, though fine-powdered talc commands a premium.
