    Uses Feldspar is a common flux and is used in various types of ceramic bodies the fluxing action depending on the amount and type of alkalies present. Unlike pegmatites and nepheline syenites feldspar has a rather slow fluxing action due to the high viscosity of the melt. Potash feldspar is generally preferred in ceramic glazes.

    Potassium feldspar melts at around 1200C higher than soda feldspar producing a more a viscous melt than does sodium feldspar. It can also produce a crystalline phase leucite that contributes to opacity. Thus in industry potash feldspars are often used more for matte glazes while soda feldspar is used for glossy glazes.
