Question

The process of making clay liquid and slippery is used for which casting?

• A. Press casting
• B. Throwing
• C. Slip casting
• D. Slab casting

Hint:

Slip casting is the method of pouring liquid clay into molds to create pottery, especially useful for intricate designs.

Answer 1

The Correct Option is C

Step 1: Define Slip Casting.
Slip casting is a ceramic forming method where liquefied clay, termed "slip," is introduced into a mold. The slip solidifies to form the desired object. This method is advantageous for producing complex or large ceramic items.
Step 2: Evaluate Methods.
- (1) Press Casting: Incorrect. This method uses compressed clay, not liquid clay in a mold.
- (2) Throwing: Incorrect. This technique involves shaping clay on a potter's wheel, not casting.
- (3) Slip Casting: Correct. This technique utilizes liquefied clay suitable for mold filling.
- (4) Slab Casting: Incorrect. This method uses flat sheets of clay, not a liquid suspension.
Step 3: Determine Correct Method.
Consequently, the appropriate selection is (3) Slip casting.
