Porcelain sculptures are delicate artworks that require precise environmental conditions to prevent damage over time. Humidity plays a critical role in their preservation, as excessive moisture can cause mold growth or structural weakening, while overly dry conditions may lead to cracking.

The ideal humidity range for storing porcelain sculptures is typically between 40% and 55% relative humidity (RH). This range minimizes the risk of moisture-related deterioration while preventing the material from becoming brittle. To maintain these levels:

1. Use a Hygrometer – A digital hygrometer helps monitor humidity accurately. Place it near the sculptures for real-time readings.

2. Climate-Controlled Storage – Store porcelain in a stable environment, avoiding basements or attics where humidity fluctuates.

3. Silica Gel Packs – These absorb excess moisture in enclosed display cases or storage boxes.

4. Avoid Direct Ventilation – Keep sculptures away from HVAC vents or windows to prevent sudden humidity changes.

5. Regular Inspections – Check for signs of efflorescence (salt deposits) or cracks, which indicate improper humidity.

For valuable or antique pieces, consult a professional conservator to tailor storage conditions. Proper humidity control ensures porcelain sculptures remain pristine for generations.
