While comparing Tremolite and Glass 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 Tremolite and Glass chemical formula.
Another important criteria for qualitative analysis of gemstones is Tremolite and Glass Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Tremolite and Glass Optical Properties during the identification of gemstone. Specific gravity of Tremolite is 2.39-4.00 whereas that of Glass is 2.39-4.00.
