Question

In which technique, clay undergoes thermal shock during rapid heating and cooling?

• A. Raku
• B. Earthenware
• C. Terracotta
• D. Mold casting

Hint:

Raku pottery is known for its unpredictable and dramatic effects, caused by the rapid cooling of the hot clay.

Answer 1

The Correct Option is A

Step 1: Understanding Raku.
Raku is a pottery technique that involves rapidly heating the clay in a kiln and then removing it while still hot to cool quickly in the open air. This rapid heating and cooling cause thermal shock, which is characteristic of this method.
Step 2: Analysis of options.
- (1) Raku: Correct, raku involves thermal shock due to rapid heating and cooling.
- (2) Earthenware: Incorrect, earthenware does not involve rapid temperature changes.
- (3) Terracotta: Incorrect, terracotta is a type of clay, not a firing technique.
- (4) Mold casting: Incorrect, mold casting involves pouring liquid clay into molds, not thermal shock.
Step 3: Conclusion.
Thus, the correct answer is (1) Raku.
