A very hard mixture consisting primarily of silicon carbide; it is used as an abrasive and, in powdered form, in a method of engraving invented by Henri Goetz. He used it to obtain a dotted effect by sprinkling it over a metal plate (usually duralumin) which was then pulled through a press, thereby causing the grains to penetrate the metal.

Description: When found in nature, fluorspar is known by the mineral name fluorite. Fluorspar is calcium fluoride (CaF 2).Metallurgical grade fluorspar (60–85% CaF 2), is traditionally used as a flux to lower the melting point of raw materials in steel production to facilitate the removal of impurities, and in the production of aluminum.. Ceramic grade fluorspar (85–95% CaF 2) is used in
