Feldspar is a group of rock-forming minerals (aluminosilicate minerals) containing potassium, sodium, or calcium. The ratio of silicon and aluminum in feldspar can range from 3:1 to 1:1. Feldspar is naturally found as a rock-forming mineral and is found on more than 50% of the earth's crust. The major applications of feldspar are in the glass and ceramic industry.
