Foitite and Kainite Physical Properties

Foitite and Kainite Chemical Formula

While comparing Foitite and Kainite 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 Foitite and Kainite chemical formula.

Foitite and Kainite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Foitite and Kainite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Foitite and Kainite Optical Properties during the identification of gemstone. Specific gravity of Foitite is 2.15 whereas that of Kainite is 2.15.
