Titanium Green

has been proposed as a substitute for the green arsenical pigments in

common use; but, apart from its expense, the colour is very inferior to

Scheele's green, &c. Titanium green is a ferrocyanide of that metal,

produced by adding yellow prussiate of potash to a solution of titanic

acid in dilute hydrochloric acid, and heating the mixture to ebullition

rapidly. The dark green precipitate is washed with water acidulated with

hydrochloric acid, and dried with great care, since it decomposes at

temperatures above 100 deg..
