Answer:

ans . option c

Explanation:

Feldspar is an important ingredient in the manufacture of glass and an important raw material as well, because it acts as a fluxing agent, reducing the melting temperature of quartz and helping to control the viscosity of glass. In the manufacturing of ceramics, feldspar is the second most important ingredient after clay.
