Feldspar: Uses And Applications

Most feldspar minerals have a specific gravity within the 2.5-2.8 range while their Mohs hardness hovers about 6 to 6.5. In addition to all these similarities in physical properties, all feldspar minerals have a vitreous luster that is mostly pearly on cluster faces. This is a great way of identifying feldspar minerals.Web

Feldspars

Feldspars are aluminosilicates, containing silicon and aluminum ions bound together by oxygen ions to form a three dimensional framework of atoms. Other ions, principally potassium, sodium, and calcium, occupy sites within the framework. Extensive chemical variation, or solid solution, occurs between orthoclase and albite, with potassium and ...Web

Orthoclase: Pink granite, Mohs hardness and moonstone

Orthoclase is a feldspar mineral with a chemical composition of KAlSi 3 O 8. It is one of the most abundant rock-forming minerals of the continental crust. Orthoclase is most widely known as the pink feldspar found in many granites and as the mineral assigned a hardness of "6" in the Mohs hardness scale. ADVERTISEMENT.Web
