Creating large-scale porcelain sculptures requires careful consideration of the clay body to ensure structural integrity and artistic expression. The most important factors include:

1. Plasticity and Workability: The clay must be malleable enough to shape intricate details while maintaining strength during construction. High plasticity clays, often blended with kaolin, are ideal for large pieces.

2. Firing Temperature: Porcelain clay bodies must withstand high firing temperatures (1200°C–1400°C) without warping or cracking. A stable thermal expansion rate is critical for large sculptures.

3. Durability and Strength: Large sculptures need a clay body with low porosity and high mechanical strength to prevent breakage during handling and display.

4. Shrinkage Rate: Minimizing shrinkage during drying and firing reduces cracking risks. Tested clay blends with predictable shrinkage rates are preferred.

5. Aesthetic Qualities: The final appearance—translucency, color, and surface texture—should align with the artist’s vision. Some clays mature to a pure white, while others develop subtle tones.

By balancing these factors, artists can select a clay body that ensures both artistic success and longevity for their large-scale porcelain creations.
