Porcelain sculptures, prized for their delicate beauty, are highly susceptible to damage when exposed to temperature fluctuations. The most common types of deterioration include:

1. Cracking and Fractures – Sudden temperature changes cause expansion and contraction, leading to structural cracks, especially in thicker sections.

2. Glaze Crazing – Thermal stress creates fine surface cracks in the glaze, compromising aesthetics and structural integrity.

3. Spalling – Rapid heating or cooling can cause layers of porcelain to flake off due to uneven expansion rates.

4. Discoloration – Repeated thermal cycling may alter the chemical composition of glazes, leading to fading or darkening.

5. Weakened Bonds – Temperature shifts weaken adhesive repairs or joints, increasing vulnerability to breakage.

To preserve porcelain sculptures, avoid placing them near heat sources, direct sunlight, or drafty areas. Proper acclimatization and controlled environments help mitigate these risks.
