Nepheline syenite

Nepheline syenite is a quartz-free aluminium silicate. It primarily comprises nepheline, microcline and albite. Because of its extremely low melting point and high alumina content, Sibelco nepheline syenite is used as a flux in ceramics, to lower melting temperatures in glass, and as a functional filler in coatings and polymers.

Syenite: Identification, Pictures, & Info for Rockhounds

Syenite is a light-colored, coarse-grained igneous rock with crystals that are visible to the naked eye. It is commonly pinkish due to its high alkali feldspar content, with little quartz. Intermixed dark, mafic minerals often give syenite a 'salt and pepper' look. It lacks features like layering, banding, or fossils.
