Creating high-detail porcelain sculptures requires careful selection of the right clay body. The most critical factors include the clay's plasticity, which ensures smooth shaping without cracking, and its fine particle size for intricate detailing. Firing temperature is another key consideration; porcelain typically requires high firing (around 1300°C) to achieve its signature translucency and strength. Additionally, the clay's shrinkage rate must be minimal to prevent distortion during drying and firing. Lastly, the purity of the clay—free from impurities like iron—ensures a flawless white finish, essential for delicate artistic work. By balancing these factors, artists can achieve stunning, durable porcelain sculptures.
