: Approximately 6 to 6.5 on the Mohs scale, often used to distinguish it from softer minerals like marble or quartzite. Density : Approximately
: On Earth, pure anorthite is restricted primarily to basic and ultrabasic igneous rocks like gabbro, picrite, or specialized formations such as the Adirondack Mountains . anorthite

Beyond its role in geology, anorthite has significant utility in manufacturing and high-tech research: : Highly porous anorthite ceramics are used as
: It is a critical component in the production of low-expansion ceramics and glass, where it helps lower sintering temperatures and increase mechanical strength.
: Highly porous anorthite ceramics are used as "green" materials for thermal insulation, sound absorption, and as catalyst carriers.
