Feldspar | Millers & Base Minerals | African Pegmatite
Potassium feldspar is commonly used as a flux in glassmaking and ceramics. Flux is a material that’s added to a solid to lower the solid’s melting point. The flux is a vital component of most glass and ceramic production because it helps control the viscosity of the glass and helps create a glassy phase in ceramics at low temperatures.

Feldspar - Wikipedia
In ceramics, the alkalis in feldspar (calcium oxide, potassium oxide, and sodium oxide) act as a flux, lowering the melting temperature of a mixture. Fluxes melt at an early stage in the firing process, forming a glassy matrix that bonds the other components of the system together.

Application Of Feldspar In Industry
Feldspar - Earth Resources Feldspar is an important source of alumina in the glassmaking and the ceramics industries. In ceramics, it acts as a flux and provides the vitreous lustre of chinaware and ceramic tiles. It is used in glazes and enamels and is an important mineral filler in paints, plastics, sealants, and adhesives.
What is Feldspar? - Industrial Minerals Association ...
The alkali content in feldspar acts as flux, lowering the glass batch melting temperature and thus reducing production costs. Ceramics: In the manufacture of ceramics, feldspar is the second most important ingredient after clay. Feldspar does not have a strict melting point, since it melts gradually over a range of temperatures.

Fluxes for Ceramics and Glaze - The Spruce Crafts
Soda feldspar, such as the commercially available Kona F-4. Nepheline syenite: A high soda feldspar that included some potassium, has a lower melting temperature than soda feldspar and is useful in the mid-range temperatures. Often abbreviated to "neph sye" by many potters. Sodium carbonate: aka soda ash. Sodium chloride: aka table salt.
