Porcelain sculptures are delicate artworks that can suffer significant damage when exposed to smoke. Recognizing the signs early is crucial for preservation and restoration. Here’s how to identify smoke-affected porcelain:

1. Discoloration: Smoke often leaves yellowish or grayish stains, especially in crevices and unglazed areas. The once-bright hues may appear dull or uneven.

2. Odor: A lingering smoky smell is a clear indicator. Gently sniff the sculpture (avoid direct contact) to detect any residual smoke scent.

3. Surface Texture: Smoke particles can create a gritty or sticky film. Run a clean, soft cloth lightly over the surface—if residue transfers, smoke damage is likely.

4. Crazing or Cracks: Prolonged exposure may worsen existing micro-cracks or cause new ones due to thermal stress, visible under bright light.

5. Soot Deposits: Check for black or dark specks in detailed areas, a telltale sign of incomplete combustion residue.

For valuable pieces, consult a professional conservator to assess and restore the sculpture safely. Early detection can prevent irreversible harm to these cherished artworks.
