Cordierite and Tinzenite Chemical Formula
While comparing Cordierite and Tinzenite 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 Cordierite and Tinzenite chemical formula.
- Chemical formula of Cordierite- Mg2Al4Si5O18
- Chemical formula of Tinzenite- (Ca,Mn2+ ,Fe2+ ) 3Al 2BSi 4O 15(OH)Anthony et al , Handbook of mineralogy (2001)
Cordierite and Tinzenite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Cordierite and Tinzenite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Cordierite and Tinzenite Optical Properties during the identification of gemstone. Specific gravity of Cordierite is 3.355-3.433 whereas that of Tinzenite is 3.355-3.433.
