Porcelain sculptures, prized for their delicate beauty, are highly vulnerable to damage from prolonged exposure to high humidity. The most common issues include mold growth in porous areas, which leaves dark stains and weakens the material. Excessive moisture also causes efflorescence—white salt deposits that form on surfaces due to mineral leaching. Structural damage occurs as humidity softens adhesives in restored pieces, leading to joint failures. Additionally, painted or glazed surfaces may develop "crazing," a network of fine cracks caused by moisture expansion. In severe cases, capillary action draws water into micro-fractures, causing irreversible clay body swelling and distortion. Preventive measures like climate-controlled display cases and silica gel packets can mitigate these risks for collectors.
