Glaucophane and Epidote Chemical Formula
While comparing Glaucophane and Epidote 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 Glaucophane and Epidote chemical formula.
- Chemical formula of Glaucophane- [ ]Na2(Mg3Al2)Si8O22(OH)2
- Chemical formula of Epidote- CaAl 2(Fe3+ ,Al)Si 3O 12(OH)Michael OâDonoghue , Gems, Sixth Edition (2006) More from other references
Glaucophane and Epidote Specific Gravity
Another important criteria for qualitative analysis of gemstones is Glaucophane and Epidote Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Glaucophane and Epidote Optical Properties during the identification of gemstone. Specific gravity of Glaucophane is 3.25-3.50 whereas that of Epidote is 3.25-3.50.
