Porcelain sculptures exposed to salt air can suffer significant deterioration over time. Recognizing the early signs of damage is crucial for preservation. Here are key indicators to watch for:

1. Discoloration: Salt deposits often leave white or grayish streaks on the surface, altering the original color.

2. Pitting and Roughness: Tiny holes or a gritty texture may appear due to salt crystals etching the glaze.

3. Glaze Erosion: The protective glaze may become dull or develop cracks, exposing the porous ceramic beneath.

4. Efflorescence: A powdery white residue forms as salt migrates to the surface and crystallizes.

5. Structural Weakness: Prolonged exposure can cause brittleness or even fractures in severe cases.

To mitigate damage, clean sculptures with distilled water and a soft brush, avoiding harsh chemicals. Store them in controlled environments away from coastal areas. Regular inspections and professional restoration can extend the life of these delicate artworks.
