Nepheline syenite supplies SiO2, Al2O3, Na2O, K2O, CaO, MgO, and Fe2O3.
Commonly used feldspathic rock. An excellent basis for glazes in the cone 4-6 range, also used in some cone 10 glazes. Manufactured by Unimin Corporation; comes from Nephton, Blue Mountain, Ontario, Canada. An igneous Precambrian feldspathic rock containing soda feldspar, potash feldspar, nepheline (K2O 3Na2O 4Al2O3 9SiO2), and small amounts of muscovite and iron minerals.
