Steatite and Schorl Chemical Formula
While comparing Steatite and Schorl 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 Steatite and Schorl chemical formula.
- Chemical formula of Steatite- Mg 3Si 4O 10(OH) 2Gemdat.org , Management Team (2012)

Steatite and Schorl Specific Gravity
Another important criteria for qualitative analysis of gemstones is Steatite and Schorl Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Steatite and Schorl Optical Properties during the identification of gemstone. Specific gravity of Steatite is 3.18-3.22 whereas that of Schorl is 3.18-3.22.
