Nephrite and Steatite Physical Properties

Nephrite and Steatite Chemical Formula

While comparing Nephrite and Steatite 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 Nephrite and Steatite chemical formula.
