Creating large porcelain sculptures is a delicate art that requires meticulous attention to prevent warping and cracking during drying and firing. Here are key techniques used by master ceramicists:

1. Slow and Even Drying: To avoid uneven shrinkage, sculptures are dried gradually in a controlled environment. Covering the piece with plastic or using damp cloths helps regulate moisture loss.

2. Reinforcement with Armatures: Internal supports like wire or clay coils provide structural stability, reducing stress during drying.

3. Proper Clay Preparation: Wedging clay thoroughly removes air pockets, while grog (fired clay particles) mixed into the clay body minimizes shrinkage and cracking.

4. Controlled Firing Cycles: A slow bisque firing (pre-firing) at low temperatures ensures moisture evaporates completely before the final high-temperature firing.

5. Use of Kiln Furniture: Shelves and stilts in the kiln promote even heat distribution, preventing thermal shock.

6. Post-Firing Cooling: Allowing the kiln to cool naturally prevents sudden temperature changes that could cause cracks.

By mastering these techniques, artists can create stunning, durable porcelain sculptures free from defects.
