Preserving porcelain sculptures in humid climates presents unique challenges that threaten their longevity and aesthetic value. One of the most significant issues is moisture absorption, which can cause irreversible damage to the delicate ceramic material. High humidity leads to the expansion and contraction of the porcelain, resulting in cracks, warping, and even structural collapse over time.

Another major concern is the growth of mold and mildew on the sculpture's surface. The porous nature of unglazed porcelain makes it particularly vulnerable to fungal infestations, which can stain and weaken the material. Salt efflorescence, caused by moisture evaporating through the ceramic body, leaves unsightly white deposits that are difficult to remove without damaging the artwork.

Humidity also accelerates the deterioration of any painted or gilded decorations on the sculpture. The moisture causes pigments to fade and metallic elements to corrode, diminishing the artwork's visual appeal. Additionally, high humidity environments often experience temperature fluctuations that further stress the porcelain through repeated expansion and contraction cycles.

To combat these challenges, conservators employ specialized techniques such as climate-controlled display cases, silica gel dehumidifiers, and regular surface cleaning with pH-neutral solutions. Preventive measures like proper storage, adequate airflow, and consistent environmental monitoring are crucial for long-term preservation. Understanding these humidity-related risks is essential for museums, collectors, and conservators working to protect these fragile cultural treasures in tropical or coastal regions.
