Porcelain sculptures are renowned for their delicate beauty and durability, often enhanced through various surface treatments. Among the most common techniques is glazing, which involves applying a glass-like coating to the surface before firing. This not only adds a glossy or matte finish but also protects the sculpture from moisture and wear.

Another popular method is polishing, where the surface is meticulously smoothed to achieve a refined, lustrous appearance. This technique is particularly favored for minimalist or contemporary designs.

Underglaze decoration is widely used to add intricate patterns or colors beneath the glaze, ensuring longevity and vibrant hues. Additionally, sgraffito—a process of scratching through a layer of slip to reveal contrasting clay beneath—creates striking textured effects.

For a more rustic look, oxide staining can be applied to highlight details or simulate aged finishes. Each of these treatments not only enhances the visual appeal of porcelain sculptures but also contributes to their preservation and artistic value.
