Microcline and Foitite Chemical Formula
While comparing Microcline and Foitite 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 Microcline and Foitite chemical formula.

Microcline and Foitite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Microcline and Foitite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Microcline and Foitite Optical Properties during the identification of gemstone. Specific gravity of Microcline is 3.17 whereas that of Foitite is 3.17.
