fluorite

fluorite (fluorspar, Blue John) Mineral, CaF2;sp. gr. 3.2; hardness 4; cubic; often yellow, green, blue, or purple, but can be colourless, pink, red, or black, and often colour banded; white streak; vitreous lustre; crystals often cubes, but can be octahedra and rhombdodecahedra, and a mixture of forms; cleavage perfect {111}; widely distributed in mineral veins alone or as a gangue mineral with metallic ores, and in association with quartz, barite, calcite, galena, cassiterite, sphalerite, and many other minerals; soluble in sulphuric acid with the evolution of hydrogen sulphide. It is used extensively as a flux in the smelting of iron, in the ceramic industry, and in the chemical industry. The deep-purple, banded variety, Blue John, is used as an ornamental stone.

fluorite

fluorite (flōō´ərīt) or fluorspar (flōō´ərspär), mineral appearing in various colors, e.g., green, yellow-brown, rose, and red. Chemically, it is calcium fluoride, CaF2. Its crystals, commonly cubic, are transparent or translucent and under certain conditions exhibit fluorescence. The mineral also occurs in granular and massive forms. Fluorite is found in various parts of the world, especially in England, Germany, Mexico, and in Kentucky and Illinois in the United States. Its chief use is as a flux in metallurgy, but it is also employed in the preparation of hydrofluoric acid and in the manufacture of opal glass and enamel; some of its colorless crystals are used for making lenses and prisms.
