The Backbone of Ceramic and Glass Innovation
Potassium Feldspar (K-Feldspar)
In KUWAIT Potassium Feldspar, commonly referred to as K-Feldspar is a group of minerals distinguished by the presence of potassium. It is one of the most important ingredients in the formation of igneous rocks and a critical raw material in the manufacturing of glass, ceramics, and porcelain.
