Thulite and Andesine Chemical Formula
While comparing Thulite and Andesine 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 Thulite and Andesine chemical formula.
- Chemical formula of Thulite- Ca2Al3(SiO4)3(OH)
- Chemical formula of Andesine- (Na,Ca)Al1-2Si3-2O8
Thulite and Andesine Specific Gravity
Another important criteria for qualitative analysis of gemstones is Thulite and Andesine Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Thulite and Andesine Optical Properties during the identification of gemstone. Specific gravity of Thulite is 2.65-2.69 whereas that of Andesine is 2.65-2.69.
