QUEEN'S YELLOW is an ancient name of Turbith Mineral, or yellow subsulphate of mercury.

QUERCITRON is the bark of the Quercus nigra, or yellow oak, a tree which grows in North America. The colouring principle of this yellow dye-stuff has been called Quercitrin, by its discoverer Chevreul. It forms small pale yellow spangles, like those ofAurum musivum, has a faint acid reaction, is pretty soluble in alcohol, hardly in ether, and little in water. Solution of alum developes from it, by degrees, a beautiful yellow dye. SEE CALICO-PRINTING and YELLOW DYE.
