Rhyolite and Caledonite Physical Properties

Rhyolite and Caledonite Chemical Formula

While comparing Rhyolite and Caledonite 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 Rhyolite and Caledonite chemical formula.

• Chemical formula of Rhyolite- 70% SiO2, Al2O3, Na2O, K2O
• Chemical formula of Caledonite- Pb 5Cu 2(SO 4) 3(CO 3)(OH) 6Anthony et al , Handbook of mineralogy (2001)

Rhyolite and Caledonite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Rhyolite and Caledonite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Rhyolite and Caledonite Optical Properties during the identification of gemstone. Specific gravity of Rhyolite is 5.6-5.76 whereas that of Caledonite is 5.6-5.76.
