Glaucophane and Bytownite Chemical Formula
While comparing Glaucophane and Bytownite 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 Bytownite chemical formula.
- Chemical formula of Glaucophane- [ ]Na2(Mg3Al2)Si8O22(OH)2
- Chemical formula of Bytownite- Ca(70-90%)Na(30-10%)(Al,Si)AlSi 2O 8Michael OâDonoghue , Gems, Sixth Edition (2006)
Glaucophane and Bytownite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Glaucophane and Bytownite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Glaucophane and Bytownite Optical Properties during the identification of gemstone. Specific gravity of Glaucophane is 2.72-2.75 whereas that of Bytownite is 2.72-2.75.
