Porcelain sculptures, cherished for their delicate beauty, often suffer significant damage when exposed to sunlight over time. The most common types of deterioration include:

1. Fading of Colors: Prolonged exposure to UV rays causes pigments to lose vibrancy, especially in hand-painted details.

2. Glaze Cracking: Temperature fluctuations and UV radiation weaken the glaze, leading to fine cracks (known as "crazing").

3. Surface Chalking: Sunlight breaks down the glaze's molecular structure, creating a powdery, dull surface.

4. Structural Weakness: Heat and light dry out the clay body, increasing brittleness and risk of breakage.

5. Discoloration: Certain minerals in porcelain react to sunlight, causing yellowing or uneven tone shifts.

To preserve these artworks, limit direct sunlight exposure, use UV-filtering glass, and maintain stable humidity levels. For antique pieces, consult a professional conservator to address existing damage.
