Step 2: Analysis of options.
- (1) Pinching: Incorrect, pinching involves shaping the clay by hand without a wheel.
- (2) Coiling: Incorrect, coiling is a technique where clay is rolled into coils and stacked to form pottery.
- (3) Slab building: Incorrect, slab building uses flat pieces of clay to construct pottery.
- (4) Throwing: Correct, this technique uses a spinning wheel to shape the clay.
Step 3: Conclusion.
Thus, the correct answer is (4) Throwing.
