When reproducing porcelain sculptures, selecting the right mold material is crucial for achieving precise details and durability. Here are the top materials used by professionals:

1. Silicone Rubber: Ideal for intricate designs, silicone molds capture fine details and are flexible, making demolding easy. They are heat-resistant and durable, suitable for multiple casts.

2. Plaster: A cost-effective option, plaster molds are great for simple shapes and low-volume reproduction. However, they are brittle and may not withstand repeated use.

3. Alginate: Often used for quick, one-time molds, alginate is perfect for delicate pieces but lacks longevity. It’s biodegradable and safe for skin contact.

4. Polyurethane Rubber: Durable and resistant to abrasion, polyurethane molds are excellent for high-volume production but require careful handling due to toxicity during mixing.

5. Latex: Flexible and affordable, latex molds are suitable for small projects but may shrink over time, affecting accuracy.

For best results, consider the sculpture’s complexity, production volume, and budget when choosing a mold material. Silicone is often the top choice for its balance of detail and durability.
