Glaucophane and Scapolite Chemical Formula
While comparing Glaucophane and Scapolite 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 Scapolite chemical formula.
- Chemical formula of Glaucophane- [ ]Na2(Mg3Al2)Si8O22(OH)2
- Chemical formula of Scapolite- Na 4Al 3Si 9O 24Cl to Ca 4Al 6Si 6O 24(CO 3,SO 4)Walter Schumann , Gemstones of the world (2001) More from other references
Glaucophane and Scapolite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Glaucophane and Scapolite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Glaucophane and Scapolite Optical Properties during the identification of gemstone. Specific gravity of Glaucophane is 2.58-2.74 whereas that of Scapolite is 2.58-2.74.
