Which mineral is harder: feldspar or quartz? Quartz 7. What mineral will scratch glass but not a streak plate? Ceramic grade fluorite (85–95% CaF 2) is used in the manufacture of opalescent glass, enamels, and cooking utensils. The highest grade, "acid grade fluorite" (97% or more CaF 2), accounts for about 95% of fluorite consumption in the US where it is used to make hydrogen fluoride and hydrofluoric acid by reacting the fluorite with sulfuric acid. Fluorite is an important industrial mineral composed of calcium and fluorine (CaF 2). It is used in a wide variety of chemical, metallurgical, and ceramic processes.
