Thulite and Steatite Chemical Formula

While comparing Thulite and Steatite 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 Steatite chemical formula.

  • Chemical formula of Thulite- Ca2Al3(SiO4)3(OH)
  • Chemical formula of Steatite- Mg 3Si 4O 10(OH) 2Gemdat.org , Management Team (2012)

Thulite and Steatite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Thulite and Steatite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Thulite and Steatite Optical Properties during the identification of gemstone. Specific gravity of Thulite is 2.20-2.80 whereas that of Steatite is 2.20-2.80.
