A common feldspar mineral, albite, is sodium aluminosilicate (NaAlSi3O8). Pegmatite and felsic igneous rocks, such as granite, are the most common, also occur in low-grade metamorphic rocks, and as authigenic albite in some sedimentary rocks. Albite usually forms brittle glassy crystals of various colors. It can be used to make glass and ceramics, but its main significance is that it is a rock-forming mineral.

Albite powder is one of the main raw materials in ceramic and glass industries.
