The thickness of a porcelain wall plays a critical role in determining a sculpture’s resistance to thermal shock, a phenomenon where rapid temperature changes cause cracking or breakage. Thicker walls tend to retain heat unevenly, creating internal stress gradients that weaken the structure. Conversely, thinner walls distribute heat more uniformly, reducing stress buildup and enhancing durability. However, excessively thin porcelain may lack structural integrity, making it prone to mechanical damage. Artists and ceramic engineers often balance thickness with material composition to optimize thermal shock resistance, ensuring longevity in both functional and decorative porcelain art. Understanding this relationship helps in crafting pieces that endure extreme temperature variations without compromising aesthetic or structural quality.
