Good name
My friend tells me I should read less Shakespeare if I want to invest in mining companies. The name is a good one:
Purple of Cassius is a purple pigment formed by the reaction of gold salts with tin(II) chloride. It has been used to impart glass with a red coloration (see cranberry glass), as well as to determine the presence of gold as a chemical test.
