Alternate Names: North Cape Nepheline Syenite, Spectrum N500
North Cape nepheline syenite is produced in the north of Norway, near the Alta fjord within the Arctic circle. This has a much higher K2O (and lower Na2O) than the Canadian material.
The analysis on the Sibelco data page likely has an error in the SiO2, we have change it from 53.2 to 57.2.
The most common source of fluxes for high and medium temperature glazes and bodies.
