A curiosity mineral. Cryolite is a stone of Divinity and higher awareness. But bauxite melts at a very temperature, in excess of 2000°C, which made electrolysis impractical and cost prohibitive. 1.) Most commercially produced aluminium is extracted by the Hall–Héroult process. Today, cryolite is substituted with synthetically produced sodium aluminium fluoride in the Hall–Héroult process, which is still used to this day to produce aluminium. Although cryolite has been found in other places, Ivittuut is the only place where this mineral has been commercially extracted. Cryolite is used in some Shino glazes in which the role of fluorine allows to intensify colors and facilitate the migration of iron to the surface while it escapes as a gas through the glaze in fusion. Besides lowering the melting point, cryolite also helps dissolves alumina well, improves the conductivity of the solution and allows electrolysis to be carried at a much higher voltage.

EPA has reassessed the cryolite tolerances and found that some are acceptable, Dissociation to NaF and NaAlF/sub 4/ can be correlated to molten densities, cryoscopic lowering, and vaporization processes. Chromite is found in beach sands derived from the weathering of chromite-bearing rocks and laterite soils that developed over peridotite. The aluminium content of cryolite is only 13 per cent, compared to 50 percent in bauxite, the major source of aluminium in the world today. Mostly considered a one locality mineral, although there are a few other minor localities, it was only found in large quantities on the west coast of Greenland. Cryolite: Image credit: James St. John/Flickr. Cryolite is an uncommon mineral of very limited natural distribution. One cryolite crystal is 1.5cm across!
