Porcelain sculptures are highly susceptible to damage in humid climates, where moisture can lead to mold growth, surface degradation, and structural instability. To preserve these delicate artworks, several proven techniques are essential.

1. Climate Control: Maintain a stable environment with 40-50% relative humidity using dehumidifiers or silica gel packs. Temperature should remain between 18-22°C (64-72°F) to prevent thermal stress.

2. Proper Storage: Store sculptures in acid-free tissue paper within sealed display cases featuring moisture-absorbing materials. Elevate pieces to avoid direct contact with surfaces prone to condensation.

3. Regular Cleaning: Use soft brushes or microfiber cloths to remove dust without abrasion. For stubborn residues, employ distilled water with minimal neutral pH cleaners, followed by thorough drying.

4. Protective Coatings: Apply museum-grade microcrystalline wax or specialized ceramic sealants to create a moisture barrier, ensuring compatibility with the porcelain’s glaze.

5. Monitoring Systems: Install hygrometers and data loggers to track environmental fluctuations, enabling timely adjustments.

For high-value pieces, consult professional conservators who can perform advanced treatments like desalination or consolidation of weakened areas. Combining these methods ensures porcelain sculptures retain their beauty and structural integrity in challenging humid conditions.
