Feldspar
Feldspars are an important group of aluminosilicates constituting 60%
of the Earth’s crust.
They crystallize from magma in both intrusive and extrusive rocks. They
occur as compact minerals, as veins, and are developed in many
metamorphic rock. They may also be found in many types of sedimentary
rock.
These rock-forming minerals are used in the ceramic and glass industry,
where they act as a source of alumina and alkali, and as a flux to
lower melting temperature.
