Talc Pigment

Description
Talc is a natural white pigment ground from talc, a very soft magnesium silicate mineral. It produces a soft, slightly warm, off white with a silky, smooth texture and a characteristic slippery feel. It has low hiding power and becomes transparent in oil, so it is used more as a working additive or medium than as a covering white.

In use, Talc improves flow, reduces settling and adds a smooth, satin body to oil, tempera and gouache. It is a classic matting agent and extender, and it makes a fine, soft filler for grounds and encaustic. It is chemically inert, lightfast and unaffected by acids or alkalis.

History
Talc has been used since antiquity in the form of soapstone (steatite), which was carved into seals, vessels and sculpture in Egypt, Mesopotamia and the Indus Valley. As a ground powder, often called French chalk, it has served for centuries as a filler in paper, paint, ceramics and cosmetics, and it remains a common extender in modern artist paints.
