How do galleries maintain humidity levels to protect rattan figurative sculptures indoors?

Galleries employ several strategies to maintain stable humidity levels and protect delicate rattan figurative sculptures indoors. Since rattan is highly sensitive to moisture fluctuations, maintaining a relative humidity (RH) of 45-55% is crucial to prevent cracking, warping, or mold growth.

Key methods include:

1. HVAC Systems: Advanced heating, ventilation, and air conditioning systems with humidifiers and dehumidifiers regulate indoor climate.

2. Hygrometers: Digital sensors monitor humidity levels in real-time, allowing quick adjustments.

3. Sealed Display Cases: Enclosed cases with silica gel packets or microclimate systems stabilize localized humidity.

4. Avoiding Direct Sunlight: UV-filtering glass and controlled lighting reduce heat-induced humidity swings.

5. Regular Maintenance: Staff routinely inspect sculptures for early signs of damage caused by humidity changes.

By combining these techniques, galleries ensure rattan artworks remain pristine for years, balancing aesthetic display with conservation needs.
