Feldspar is a raw material comprising aluminosilicate minerals such as calcium, potassium and sodium. These minerals are some of the most common, occurring in all classes of rock. As a result of their commonality, there are numerous types of feldspars with different mineral contents.
Feldspar is valuable in glass and ceramic manufacturing, and it strengthens products and enhances their color. Manufacturers melt feldspar into a glaze that provides a strengthening coat over a product while softening it and lowering its melting point.
The ideal mineral composition of feldspar varies with the application. There is a demand for compositional verification when purchasing feldspars for manufacturing use. McCreath Laboratories offers feldspar testing services from ISO/IEC 17025:2017 accredited laboratories. Our tests yield accurate, impartial data regarding the mineral composition of feldspar samples.
