What Is Soda Feldspar

Thus, in industry, potash feldspars are often used more for matte glazes while soda feldspar is used for glossy glazes. What does feldspar do in a glaze? In glazes feldspar promotes melting at medium and high temperatures (feldspars are the primary ingredient in most high temperature raw glazes). Sodium feldspars are most common and used mainly as a source of alkalis. What is the formula of ...

Feldspar – (Potassium)

Feldspar does not have a strict melting point, since it melts gradually over a range of temperatures. This greatly facilitates the melting of quartz and clays and, through appropriate mixing, allows modulations of this important step of ceramic making. Feldspars are used as fluxing agents to form a glassy phase at low temperatures and as a source
