Foitite and Fire Agate Physical Properties

Foitite and Fire Agate Chemical Formula

While comparing Foitite and Fire Agate 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 Foitite and Fire Agate chemical formula.

• Chemical formula of Foitite- Na x[Fe2+2(Al,Fe3+ )]Al 6(BO 3) 3Si 6O 18(OH) 4Anthony et al , Handbook of mineralogy (2001)
• Chemical formula of Fire Agate- SiO 2Arthur Thomas , Gemstones (2009)

Foitite and Fire Agate Specific Gravity

Another important criteria for qualitative analysis of gemstones is Foitite and Fire Agate Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Foitite and Fire Agate Optical Properties during the identification of gemstone. Specific gravity of Foitite is 2.60-2.64 whereas that of Fire Agate is 2.60-2.64.
