Albite: The plagioclase feldspar mineral Albite,

Albite is also a common accessory mineral to many rare and unusual minerals. The iridescent variety Peristerite sometimes exhibits an adularescent sheen. This produces an unusual form of Moonstone. Albite sometimes forms in association with the feldspar mineral Microcline in alternating patterns, and forms a feldspar rock known as Perthite.THE FELDSPAR GROUP OF MINERALS,The feldspar group is a fairly large group with nearly 20 members recognized, but only nine are well known and common. Those few, however, make up the greatest percentage of mineralsUSGS Minerals Information: Feldspar,In glassmaking, feldspar provides alumina for improving hardness, durability, and resistance to chemical corrosion. In ceramics, feldspar is used as a flux, lowering the vitrifying temperature of a ceramic body during firing and forming a glassy phase.

Most deposits offer sodium feldspar as well as potassium feldspar and mixed feldspars. Feldspars are primarily used in industrial applications for their alumina and alkali content.Plagioclase Feldspar: A group of common rock-forming minerals,“Plagioclase” is the name of a group of feldspar minerals that form a solid solution series ranging from pure albite, Na(AlSi 3 O 8), to pure anorthite, Ca(Al 2 Si 2 O 8). Minerals in this series are a homogenous mixture of albite and anorthite.
