Composition: Calcium fluoride
Nomenclature: Named after the Latin word "fluere" which means "to flow" because it melts easily.
Industrial Uses: Flux for iron and steel-making, carvings, novelty gemstones.
Additional Notes: The phenomenon of fluorescence (the glowing of a substance when exposed to a source of high-energy light) was named after fluorite because fluorescence was first observed in the mineral. Fluorite is also referred to as fluorspar, especially in mining literature.
