In ceramics, feldspars are used in glazes and clay bodies. They vitrify stonewares and porcelains. They supply KNaO flux to glazes to help them melt.
Feldspars are abundant and varied in nature. They contain small amounts of quartz (while nepheline syenite does not).
The most common source of fluxes for high and medium temperature glazes and bodies.
