Preserving porcelain sculptures in tropical climates presents unique challenges due to the region's high humidity, temperature fluctuations, and biological threats. The most significant issues include:

1. Humidity Damage: Constant exposure to moisture causes clay particles to expand and contract, leading to cracks and glaze deterioration.

2. Mold and Fungus Growth: Warm, damp conditions accelerate mold formation, which can permanently stain or weaken the sculpture’s structure.

3. Salt Efflorescence: High humidity encourages salt migration to the surface, creating unsightly white deposits that degrade the artwork.

4. Insect Infestations: Termites and other pests are attracted to organic materials used in older porcelain pieces, causing irreversible damage.

5. UV Exposure: Intense sunlight in tropical zones fades pigments and weakens glazes over time.

To mitigate these risks, experts recommend controlled storage with dehumidifiers, silica gel packets, and UV-filtering display cases. Regular inspections and gentle cleaning with pH-neutral solutions are also crucial for long-term preservation.
