Oligoclase and Bort Physical Properties

Oligoclase and Bort Chemical Formula

While comparing Oligoclase and Bort 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 Bort chemical formula.

• Chemical formula of Oligoclase- Na(90-70%)Ca(10-30%)(Al,Si)AlSi 2O 8Michael O’Donoghue , Gems, Sixth Edition (2006)
• Chemical formula of Bort- C

Oligoclase and Bort Specific Gravity

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