Generally, sodium feldspar appears to be glass-like crystal, it can be colorless, and it can be used as raw material for glass and ceramics. Sodium feldspar is mainly used to manufacture ceramics, soap, ceramic tile, floor tile, glass, grinding materials and grinding tools, etc. In ceramic manufacturing, it is mainly used in glaze.

Feldspar has the main contributions: 35% for GWP, 42% for AP, 30% for EP, 67% for ODP and 42% for POCP. Clay and kaolin contribute 20% and 19% of the GWP respectively, and alumina with 25%. Milled alumina has the highest contribution for ADPe, about 60% due to the consumption of caustic soda during the Bayer process.

Glaze is a layer of liquid glass applied onto a green body. Many different techniques are used for applying the enamel uniformly to the surface of the tiles.
