Porcelain sculptures are delicate artworks that can suffer damage from sudden temperature changes. To preserve their beauty and structural integrity, follow these expert-recommended methods:

1. Climate-Controlled Storage: Maintain a stable environment between 65-75°F (18-24°C) with 40-50% humidity. Avoid placing sculptures near heaters, air conditioners, or direct sunlight.

2. Insulated Display Cases: Use museum-grade cases with UV-filtering glass and thermal insulation to buffer against external temperature shifts.

3. Gradual Acclimatization: When moving sculptures between environments, allow 24-48 hours for gradual adjustment to prevent thermal shock.

4. Humidity Control: Pair silica gel packs or dehumidifiers with hygrometers to monitor moisture levels, preventing condensation and cracking.

5. Avoid Outdoor Exposure: Porcelain expands and contracts with temperature changes. For outdoor displays, use weather-resistant coatings and bring pieces indoors during extreme seasons.

6. Professional Restoration: If damage occurs, consult ceramic conservation specialists for repairs using reversible, archival-quality materials.

By implementing these measures, collectors and museums can significantly reduce risks posed by temperature fluctuations, ensuring porcelain sculptures remain pristine for generations.
