Anotations

Scope note:

Synthetically prepared azure blue pigment composed of basic copper carbonate, first made in the 17th century and more widely used in the 19th century for both distemper and oil based interior house paints. It is no longer commonly used. Blue verditer particles are more rounded and regular in size than ground azurite.
