Anotations

Scope note:

A green pigment originally composed of basic copper chloride (atacamite), developed in 1795 by the Brunswick brothers by placing copper filings in an ammonium chloride solution, then collecting the precipitate. By the 19th century, Brunswick green was prepared by mixing Prussian blue and chrome yellow, although this mixture is more commonly called "chrome green."
