Description
An obsolete organic colorant thought to have come from gallstone of an ox. Gallstones were ground into a golden yellow powder then mixed with gum arabic for a transparent yellow paint. By the end of the 18th century, a substitute made from Quercitron yellow was sold under the name of gallstone. Both colorants were fugitive and rarely used in paints.
