Cryolite and Charlesite Chemical Formula

While comparing Cryolite and Charlesite physical properties, the important data you should know is its chemical composition. Since chemical formula defines the molecular structure of the crystal, most of the physical properties like color, tenacity, solubility are governed by Cryolite and Charlesite chemical formula.

  • Chemical formula of Cryolite- Na 3AlF 6Ulrich Henn and Claudio C.
  • Chemical formula of Charlesite- Ca6(Al,Si)2(SO4)2B(OH)4(OH,O)12•26(H2O)

Cryolite and Charlesite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Cryolite and Charlesite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Cryolite and Charlesite Optical Properties during the identification of gemstone. Specific gravity of Cryolite is 1.79 whereas that of Charlesite is 1.79.
