Orthoclase and Cryolite Chemical Formula

While comparing Orthoclase and Cryolite 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 Orthoclase and Cryolite chemical formula.

Orthoclase and Cryolite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Orthoclase and Cryolite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Orthoclase and Cryolite Optical Properties during the identification of gemstone. Specific gravity of Orthoclase is 2.97 whereas that of Cryolite is 2.97.
