Feldspar – Micron

Ceramic grade feldspars are typically ground to no more than 75 μm (200 mesh). Just like in glassmaking, the basic components of the feldspars (sodium, potassium and calcium) behave as fluxes – they work with soda ash (like in soda glass) to reduce the melting temperature and increase the fusibility of all components.
