Porcelain sculptures are delicate artworks that often require repair due to accidental damage or aging. Identifying whether a piece has been restored is crucial for collectors and enthusiasts. Here are key signs to look for:

1. Visible Glue Lines: Repaired fractures may show thin, uneven adhesive residues, especially under UV light.

2. Mismatched Glazes: Restored areas might lack the original glaze’s luster or color consistency.

3. Surface Irregularities: Smooth transitions between fragments suggest professional repair, while rough edges indicate amateur work.

4. Weight Discrepancies: Replaced sections may feel lighter or heavier due to different materials.

5. Microscopic Bubbles: Overheated glue or mismatched clay can leave tiny bubbles near seams.

For valuable pieces, consult a professional appraiser to confirm authenticity. Understanding these signs helps preserve the integrity of your collection.
