Verdigris (medicine)


verdigris


1. <chemistry> A green poisonous substance used as a pigment and drug, obtained by the action of acetic acid on copper, and consisting essentially of a complex mixture of several basic copper acetates.

2. The green rust formed on copper.

This rust is a carbonate of copper, and should not be confounded with true verdigris.

<chemistry> Blue verdigris, an acid copper acetate; so called because the acetic acid used in making it was obtained from distilled vinegar. Verdigris green, clear bluish green, the colour of verdigris.

Origin: F. Vert-de-gris, apparently from verd, vert, green + de of + gris gray, but really a corruption of LL. Viride aeris (equivalent to L. Aerugo), from L. Viridis green + aes, aeris, brass. See Verdant, and 2d Ore.
