Using low-quality clay or impurities in porcelain sculpture production can lead to significant artistic and structural problems. Inferior clay often lacks the necessary plasticity, making it difficult to shape and increasing the risk of cracks during drying or firing. Impurities like sand or organic matter may cause uneven textures, discoloration, or even explosions in the kiln due to trapped gases.

Poor-quality materials also compromise durability, resulting in fragile sculptures prone to breakage. Glazes may not adhere properly, leading to peeling or bubbling. Additionally, impurities can react unpredictably at high temperatures, creating undesirable color shifts or surface defects.

For professional artists and hobbyists alike, investing in high-grade clay ensures smoother workflows, consistent results, and long-lasting artworks. Proper material selection is crucial for achieving the delicate translucency and strength that define quality porcelain sculptures.
