Andesine and Sodalite Chemical Formula
While comparing Andesine and Sodalite 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 Andesine and Sodalite chemical formula.
- Chemical formula of Andesine- (Na,Ca)Al1-2Si3-2O8
- Chemical formula of Sodalite- Na8Al6Si6O24Cl2
Andesine and Sodalite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Andesine and Sodalite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Andesine and Sodalite Optical Properties during the identification of gemstone. Specific gravity of Andesine is 2.15-2.40 whereas that of Sodalite is 2.15-2.40.
