Description

Synthetically prepared green basic copper carbonate (analogue of malachite). Green verditer was an inexpensive green pigment first manufactured in the 16th century (a byproduct of the silver refining process) by pouring copper nitrate on calcium carbonate (whiting), followed by washing and drying. In the 18th and 19th centuries, green verditer was used for distemper housepaints and widely used in wallpapers. It has not been extensively documented in easel paintings, but some sources believe it was used more widely than previously believed. It was not usually recommended for use in oil, as John Smith reported in his 1723 edition of "The Art of Painting in Oyl" that green verditer is a "sandy" color that lacked "good body" (p. 24). He goes on to report that "with all the grinding imaginable" the verditers and smalts "will never be well imbodied [sp] with the oyl" nor do they "lye [sp] intirely [sp] smooth in the Working." (p. 28). Despite this, he lists the pigment as a component for painting colors such as "Sea Green" and "Leaves of Trees". By the early 19th century, green verditer saw large-scale, industrial preparation by precipitation from a solution of copper sulphate, to which potassium carbonate was added.
