    Chromite can be used as a refractory material, because it has a high heat stability. The chromium extracted from chromite is used in chrome plating and alloying for production of corrosion resistant superalloys, nichrome, and stainless steel. Chromium is used as a pigment for glass, glazes, and paint, and as an oxidizing agent for tanning leather. It is also sometimes used as a gemstone. Porcelain tiles are often produced with many different colours and pigmentations. The usual contributor t
