Porcelain sculptures are treasured for their historical and artistic value, but over-restoration can diminish their authenticity. Here are key signs to identify over-restored pieces:

1. Unnatural Surface Texture: Over-restored areas often appear too smooth or glossy compared to the original patina. Authentic antique porcelain typically shows subtle wear and age-related texture variations.

2. Mismatched Colors: Restoration paint may not perfectly match the original glaze, resulting in noticeable color discrepancies under natural light.

3. Excessive Repairs: Overzealous restoration can fill in intentional cracks or wear, erasing the sculpture’s natural aging process.

4. Loss of Detail: Fine details like hand-painted patterns or delicate edges may appear blurred or simplified due to aggressive cleaning or repainting.

5. Inconsistent Aging: A well-restored piece should age uniformly. If some areas look artificially aged while others appear pristine, it may indicate over-restoration.

By carefully examining these aspects, collectors and conservators can preserve the integrity of porcelain sculptures while avoiding the pitfalls of excessive restoration.
