In glassmaking, the mineral's alumina content enhances the workability of the product and improves product hardness, durability, thermal endurance and resistance to chemical corrosion. Feldspar also serves as a binder and filler in paints and in various abrasive applications. In 2010 in the U.S., some 70 percent of feldspar was used for glass.
In glassmaking, alumina from feldspar actually improves the product's hardness, durability, and resistance against chemical corrosion. In ceramics, the alkalis in feldspar are calcium oxide, potassium oxide, and sodium oxide. All of these act as a flux that eventually lowers the melting temperature of the mixture.

Feldspar is an important ingredient in glassmaking. In ceramics it acts as a flux which imparts the vitreous lustre to chinaware, sanitaryware and ceramic tiles. It is used in glazes and enamels, and is an important mineral filler in paints, plastics, sealants and adhesives.
Feldspars (sometimes spelled felspars) are a group of rock-forming aluminium tectosilicate minerals, also containing other cations such as sodium, calcium, potassium, or barium. The most common members of the feldspar group are the plagioclase (sodium-calcium) feldspars and the alkali (potassium-sodium) feldspars. Feldspars make up about 60% of …

In ceramics, feldspar is used rubber, and other products, usage was still significant.
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 …
In glassmaking, feldspar improves hardness, durability, and resistance to corrosion from chemicals. In ceramics, it acts as a flux, lowering the melting temperature of a mixture, forming a glassy matric that bonds the other components together. Feldspars can be found in colors from pink, white, grey, brown, and blue. ...
Feldspar, usually of the potassium or sodium type or mixtures of the two, is principally used in the manufacture of glass and ceramics. In both applications it acts as a flux. Feldspar's alkali content …
