Porcelain sculptures are delicate artworks that require careful preservation to withstand environmental factors over time. Here are the most effective ways to protect them:

1. Control Humidity Levels: Porcelain is sensitive to moisture. Maintain a stable humidity level (40-60%) to prevent cracking or warping. Use dehumidifiers in damp climates and avoid placing sculptures near windows or bathrooms.

2. Limit UV Exposure: Direct sunlight can fade colors and weaken the material. Display sculptures away from windows or use UV-filtering glass in display cases.

3. Dust Regularly: Use a soft brush or microfiber cloth to remove dust gently. Avoid harsh chemicals that could damage the glaze.

4. Proper Handling: Always lift porcelain sculptures with both hands, supporting the base. Wear cotton gloves to prevent oils from your skin from affecting the surface.

5. Display Safely: Place sculptures on stable surfaces away from high-traffic areas. Use padded mounts or vibration-absorbing materials to prevent accidental falls.

6. Climate-Controlled Storage: If storing long-term, use acid-free tissue paper and sturdy boxes in a temperature-controlled environment.

By following these practices, collectors can ensure their porcelain sculptures remain pristine for generations, preserving both their beauty and value.
