Step 1: Understanding the Pitching Method.
Pitching is a method used to join two parts of pottery, typically in the wet stage. Slip, a mixture of clay and water, is applied to the edges to help bond the parts together.
Step 2: Analysis of options.
- (1) Slip: Correct, slip is the material used to connect two parts in the pitching method.
- (2) POP: Incorrect, Plaster of Paris is used for molding, not for joining parts.
- (3) Fevicol: Incorrect, Fevicol is an adhesive but not typically used in ceramic work.
- (4) Grog: Incorrect, grog is ground-up fired clay used to reduce shrinkage, not for joining parts.
Step 3: Conclusion.
Thus, the correct answer is (1) Slip.
