Question

Which of the following is a common flux used in glazes?

• A. Feldspar
• B. Silica
• C. Kaolin
• D. Iron Oxide

Hint:

Feldspar is a common flux in glazes and helps to lower the melting point of the glaze mixture.

Answer 1

The Correct Option is A

Step 1: Understanding Flux in Glazes.
Feldspar is a common flux in ceramic glazes. It lowers the melting point of other components and promotes better fusion during firing.
Step 2: Analysis of options.
- (1) Feldspar: Correct, it is a primary flux in glazes.
- (2) Silica: Incorrect, silica is used to provide structure but is not a flux.
- (3) Kaolin: Incorrect, kaolin is a type of clay, not a flux.
- (4) Iron Oxide: Incorrect, iron oxide is used for coloring, not as a flux.
Step 3: Conclusion.
Thus, the correct answer is (1) Feldspar.
