The answer Is feldspar
it is a rock-forming mineral which has particular importance in the glass and ceramics industries since it works as a fluxing agent. This means that feldspar reduces the melting temperature of quartz, consequently helping to control the viscosity of glass. Moreover, this rock-forming mineral is one of the most common minerals in existence, forming approximately 60% of earth’s terrestrial rocks. Finally, each year about 600,000 tons of feldspar is mined in the United States from quarries in South Dakota, Oklahoma, Virginia, California, North Carolina, and Idaho.
