Fluorite
Variety: Calcium fluoride
Hardness: 4 Density: 3.2 Composition: CaF2 Fluorite comes from the Latin fluere (color), as its color is highly variable. Its luster is vitreous and generally translucent and sometimes transparent.
When the stone is heated, becomes luminescent (TL). It is used as the flux by the steel industry, aluminum, glass and ceramics. It is also used in certain optical instruments for its very pure and clear varieties. References |
