Blue Verditer

or Verditer, is an oxide of copper, formed by precipitating nitrate of

copper with lime. It is of a beautiful light blue colour, little

affected by light, but greened and ultimately blackened by time, damp,

and impure air--changes which ensue even more rapidly in oil than in

water. It is mostly confined to distemper painting and paper-staining.
