feldspar as flux material

Feldspar Statistics and Information

In glassmaking, feldspar provides alumina for improving hardness, durability, and resistance to chemical corrosion In ceramics, feldspar is used as a flux, lowering the vitrifying temperature of a ceramic body during firing and forming a glassy phase Glass and ceramics continued to be the major end uses of feldspar.

Understanding Glazes

To provide silica in the glaze, we need a material than contains: SiO2=Silicon Dioxide, comes from flint, quartz and pure silica To provide alumina in the glaze, we need a material that contains: Al2O3=Aluminum Oxide, comes from feldspar, cryolite, clay Flux Silica and alumina would create a glaze if fired hot enough.

Feldspar

Feldspar, in this industry, is valued for two purposes, firstly, it acts as a flux and secondly, for alumina content Alumina provides the resistance in glass to impact, bendings, and thermal shock In ceramic bodies, potash feldspar is preferred although soda feldspar works as a good flux and can be satisfactorily used in developing ceramic.
