Hanksite and Howlite Chemical Formula
While comparing Hanksite and Howlite 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 Hanksite and Howlite chemical formula.
- Chemical formula of Hanksite- KNa22(SO4)9(CO3)2Cl
- Chemical formula of Howlite- Ca 2B 5SiO 9(OH) 5Michael OâDonoghue , Gems, Sixth Edition (2006) More from other references
Hanksite and Howlite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Hanksite and Howlite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Hanksite and Howlite Optical Properties during the identification of gemstone. Specific gravity of Hanksite is 2.45-2.58 whereas that of Howlite is 2.45-2.58.
