Also known as Chromium (III) Oxide, it is used as an inorganic pigment in paints, architectural coatings, plastics, roofing tiles and ceramic tiles. Chrome Oxide Green is also used in heavy-duty applications in the construction of high temperature and abrasion-resistant refractory brick for glass and fiberglass.

Note
Amphoteric chrome oxide is the only stable oxide of chromium metal and can be used at all temperatures to 1200C. This leaves a margin before it begins to volatilize around 1240C, the fumes are very toxic.
-Chromium is a 'fast' color, meaning it produces its characteristic green in slow or fast and oxidizing or reducing firing. It is also used in paints and dyes. The green color produced by chrome only is generally a drab army-helmet green.
-Chromium is used in the glass industry to make green glass (up to 1%). Antimony is sometimes used as a reducing agent to ensure an emerald green.

Because of its considerable stability, chromia is a commonly used pigment. It was originally called viridian. It is used in paints, inks, and glasses. It is the colorant in "chrome green" and "institutional green." Chromium(III) oxide is a precursor to the magnetic pigment chromium dioxide, by the following reaction.
Along with many other oxides, it is used as a compound when polishing (also called stropping) the edges of knives, razors, surfaces of optical devices etc. on a piece of leather, balsa, cloth or other material. It is available in powder or wax form, and in this context it is known as "green compound
