Porcelain sculptures are delicate artworks that require careful preservation, especially when displayed in areas exposed to ultraviolet (UV) light. UV radiation can cause irreversible damage, such as fading, discoloration, and material degradation. To safeguard these precious pieces, consider the following proven methods:

1. Use UV-Filtering Glass or Acrylic: Display cases made with UV-filtering materials block up to 99% of harmful rays while maintaining clarity for viewing.

2. Control Lighting Exposure: Opt for LED or low-UV lighting systems and limit exposure time. Position sculptures away from direct sunlight or windows.

3. Install UV-Blocking Window Films: If natural light is unavoidable, apply window films that filter out UV wavelengths without darkening the space.

4. Rotate Exhibits Regularly: Reduce cumulative UV exposure by periodically rotating displayed sculptures with stored ones.

5. Monitor Environmental Conditions: Use UV sensors to track light levels and ensure they remain within safe thresholds (typically below 50 lux for sensitive pieces).

6. Apply Protective Coatings: Specialized conservation varnishes can provide an additional layer of UV resistance for certain porcelain types.

For museums and private collectors, combining these methods ensures long-term preservation while allowing the beauty of porcelain sculptures to be appreciated. Consulting a conservation specialist can provide tailored solutions for high-value or historically significant pieces.
