Porcelain sculptures are delicate and prone to damage, but with the right techniques, chips and cracks can often be repaired effectively. Here are the most common methods used to restore these fragile artworks:

1. Adhesive Bonding: For clean breaks, specialized porcelain adhesives or epoxy resins can reattach fragments seamlessly. Cyanoacrylate (super glue) is a quick fix but may yellow over time, while two-part epoxy offers stronger, longer-lasting results.

2. Filling Gaps: If small pieces are missing, fillers like porcelain putty or acrylic-based compounds can recreate the missing sections. These are sanded and painted to match the original surface.

3. Pin Reinforcement: For larger cracks, a technique involving tiny metal pins drilled into the sculpture provides structural support before adhesive is applied.

4. Professional Restoration: Severe damage may require professional conservators who use advanced materials like reversible adhesives and custom-matched glazes to preserve the sculpture’s value.

5. Surface Refinishing: After repair, airbrushing or hand-painting with ceramic paints blends the repaired areas into the original design.

Preventive measures, such as avoiding temperature fluctuations and handling with care, can minimize future damage. Always test adhesives on inconspicuous areas first and consult experts for valuable or antique pieces.
