FULLN CHEMICAL Ceramic glaze pigment Malachite green (Cobalt-chrome-green) is a blue green inorganic pigment obtained by mixing, calcination and micropowder treatment of several or more combinations of raw materials such as zinc oxide, cobalt oxide, chrome green and alumina. During the calcination at high temperature, zinc oxide (Zn2+), cobalt oxide (Co2+), chrome green (Cr3+) and alumina (Al3+) react with each other and uniformly diffuse to form a substance with spinel structure, whose composition may contain a small amount of boric acid, potassium chloride and quartz. It can be fired in oxidizing and reducing atmosphere. It's suitable for various of glazes.
