Creating porcelain sculpture multiples with precise dimensional accuracy is a complex process fraught with challenges. One of the most common issues is mold shrinkage, as porcelain clay contracts significantly during drying and firing, often leading to inconsistencies in size. The material's composition also plays a critical role; slight variations in clay consistency or moisture content can alter the final dimensions.

Firing techniques present another hurdle. Uneven kiln temperatures or rapid heating/cooling cycles may cause warping or cracking, distorting the sculpture's intended form. Additionally, intricate designs with fine details are particularly susceptible to deformation, requiring meticulous mold-making and careful handling.

Artists must also account for glaze application, as thick layers can further shrink or shift dimensions during firing. Mastering these variables demands both technical expertise and artistic precision, making dimensional accuracy a persistent challenge in porcelain sculpture multiples.
