Oligoclase and Mellite Physical Properties

Oligoclase and Mellite Chemical Formula

While comparing Oligoclase and Mellite 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 Oligoclase and Mellite chemical formula.

Oligoclase and Mellite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Oligoclase and Mellite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Oligoclase and Mellite Optical Properties during the identification of gemstone. Specific gravity of Oligoclase is 1.58-1.60 whereas that of Mellite is 1.58-1.60.
