Nepheline Syenite - shop.clay-planet.com

Nepheline syenite contributes high alumina without associated free silica in its raw form. This makes it an excellent tile filler and melter, especially for fast firing. Nepheline syenite fluxes and forms silicates with free silica in bodies without contributing any free silica itself, thereby stabilizing the expansion curve of the fired body.

Nepheline Syenite | CCG NZ

Nepheline syenite melts lower than feldspars. For example, it is possible to make a very white vitreous medium temperature porcelain (firing as low as cone 4, but more practically at cone 6). Up to 50% nepheline syenite will be needed at cone 4, 35-40% at cone 6. 20% silica is needed or glazes will craze. The rest is clay, preferably kaolin.
