Porcelain sculptures are delicate works of art that require careful maintenance to preserve their beauty and integrity. Dust and pollutants can gradually degrade their surface, leading to discoloration or damage. Here are the most effective ways to protect your porcelain sculptures:

1. Regular Dusting with Soft Brushes

Use a soft, natural-bristle brush or microfiber cloth to gently remove dust. Avoid harsh materials that could scratch the surface.

2. Display in Enclosed Cabinets

Keep sculptures in glass display cases or cabinets to minimize exposure to airborne dust and pollutants.

3. Control Humidity and Temperature

Maintain a stable environment (50-60% humidity, 65-75°F) to prevent cracking or mold growth.

4. Avoid Direct Sunlight

UV rays can fade colors and weaken porcelain. Place sculptures away from windows or use UV-filtering glass.

5. Use Protective Coatings

Apply museum-grade wax or acrylic sealants (tested on a small area first) to create a barrier against pollutants.

6. Professional Cleaning for Stubborn Stains

For deep cleaning, consult a conservator—never use water or chemicals without expert advice.

7. Rotate Display Pieces

Periodically store displayed sculptures in acid-free tissue paper inside archival boxes to give them a "rest" from environmental exposure.

By implementing these protective measures, collectors can ensure their porcelain sculptures remain pristine for generations. Remember, prevention is always better than restoration when it comes to delicate ceramic art.
