Porcelain sculptures are admired for their delicate beauty, but their intricate designs often hide structural vulnerabilities. One of the most frequent issues is thin or uneven walls, which can lead to cracks or breaks during firing or handling. Poorly executed joins between components are another common flaw, as weak adhesion points may separate under stress. Additionally, uneven drying rates in thicker sections can cause warping or internal fractures.

Another critical weakness is inadequate support for overhanging elements, which may sag or collapse. The choice of clay body also plays a role - some formulations lack sufficient strength for complex designs. To mitigate these issues, artists should maintain consistent wall thickness, reinforce joins with scoring and slip, and allow for gradual, even drying. Strategic use of internal supports and careful clay selection can significantly improve structural integrity while preserving aesthetic appeal.

Understanding these common weaknesses helps artists create more durable porcelain sculptures without compromising their artistic vision. Proper planning and technique can transform fragile pieces into lasting works of art.
