What’s Whiting?

What is whiting and how is it used?

Michael Dresdner: Whiting, often called “gilder’s whiting” is another name for calcium carbonate. It is used as a filler to thicken coatings, putties, glues, and pore fillers, and sometimes even as an abrasive for polishing lacquer. The name gilder’s whiting comes from the fact that gilders, or gold leaf finishers, traditionally used it to create the smooth, plaster-like ground coats of gesso used under gold leaf.

Richard Jones: Powder of calcium carbonate.
