Andesine and Hydrophane Chemical Formula
While comparing Andesine and Hydrophane 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 Hydrophane chemical formula.
- Chemical formula of Andesine- (Na,Ca)Al1-2Si3-2O8
- Chemical formula of Hydrophane- SiO 2 · nH 2OWalter Schumann , Gemstones of the world (2001)
Andesine and Hydrophane Specific Gravity
Another important criteria for qualitative analysis of gemstones is Andesine and Hydrophane Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Andesine and Hydrophane Optical Properties during the identification of gemstone. Specific gravity of Andesine is 1.98-2.50 whereas that of Hydrophane is 1.98-2.50.
