While comparing Glass and Hodgkinsonite 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 Glass and Hodgkinsonite chemical formula.
Another important criteria for qualitative analysis of gemstones is Glass and Hodgkinsonite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Glass and Hodgkinsonite Optical Properties during the identification of gemstone. Specific gravity of Glass is 4.06-4.08 whereas that of Hodgkinsonite is 4.06-4.08.
