Repairing broken porcelain sculptures requires the right adhesive to ensure a strong and lasting bond. The most commonly used adhesives include:

1. Epoxy Resin – A two-part adhesive known for its high strength and durability. It’s ideal for large or load-bearing porcelain repairs but requires careful mixing and curing time.

2. Cyanoacrylate (Super Glue) – Best for small, clean breaks due to its fast-drying properties. It forms a strong bond quickly but may become brittle over time.

3. Porcelain or Ceramic Adhesive – Specifically formulated for ceramics, these adhesives offer excellent bonding and resistance to moisture and heat.

4. Polyurethane Glue – Flexible and waterproof, making it suitable for repairs that may undergo stress or temperature changes.

5. UV-Curing Adhesive – A modern option that hardens under UV light, providing a clear and strong bond for delicate porcelain pieces.

Choosing the right adhesive depends on the size of the break, the sculpture’s use, and desired finish. Always clean surfaces thoroughly before application for optimal results.
