Question

Which type of firing involves a reduction atmosphere to produce unique surface effects?

• A. Electric Firing
• B. Raku Firing
• C. Gas Firing
• D. Saggar Firing

Hint:

Raku firing is known for its dramatic surface effects, including crackling and color shifts, achieved by a reduction atmosphere.

Answer 1

The Correct Option is B

Step 1: Understanding Types of Firing.
Raku firing is a ceramic firing process that involves a reduction atmosphere, where oxygen is deprived to create unique surface effects such as crackling and color changes.
Step 2: Analysis of options.
- (1) Electric Firing: Incorrect, electric firing uses an electric kiln and is typically done in an oxidizing atmosphere.
- (2) Raku Firing: Correct, this process uses a reduction atmosphere to create unique surface effects.
- (3) Gas Firing: Incorrect, while gas firing can involve reduction, it is not as specific as raku firing.
- (4) Saggar Firing: Incorrect, saggar firing uses a sealed container but does not create the same reduction effects as raku.
Step 3: Conclusion.
Thus, the correct answer is (2) Raku Firing.
