Anorthite Now
: During the early cooling of the Moon, anorthite crystals were less dense than the surrounding basaltic magma. They floated to the surface, forming a thick crust of anorthosite (a rock composed of 90–100% plagioclase).
: It is a critical component in the production of low-expansion ceramics and glass, where it helps lower sintering temperatures and increase mechanical strength. anorthite
: Typically white, grey, or colorless; can also appear yellowish or reddish. : During the early cooling of the Moon,
: Highly porous anorthite ceramics are used as "green" materials for thermal insulation, sound absorption, and as catalyst carriers. : Typically white, grey, or colorless; can also

Anorthite is central to the "Magma Ocean" theory of lunar formation.
