Mold growth on porcelain sculptures can compromise their aesthetic and structural integrity. Recognizing early signs is crucial for preservation. Here’s how to spot mold:

1. Discoloration: Look for irregular patches of green, black, or white spots, often fuzzy or powdery, contrasting with the porcelain’s original glaze.

2. Musty Odor: Mold emits a damp, earthy smell. Hold the sculpture close (without inhaling deeply) to detect unusual odors.

3. Surface Texture Changes: Gently run a gloved finger over suspicious areas. Mold may cause roughness or pitting beneath the glaze.

4. Cracks or Warping: Prolonged mold exposure weakens porcelain, leading to hairline cracks or warped sections due to moisture retention.

5. Historical Context: If the sculpture was stored in humid environments (e.g., basements), inspect it thoroughly—mold thrives in damp conditions.

Prevention Tips: Store porcelain in climate-controlled spaces with silica gel packs to absorb moisture. Clean with a soft, dry brush and consult a conservator for severe cases. Early detection saves irreplaceable art!
