When reproducing porcelain sculptures, selecting the right mold material is crucial for achieving precision and durability. Here are the top materials used in the process:

1. Silicone Rubber: Ideal for intricate details, silicone molds are flexible, durable, and non-stick, making them perfect for delicate porcelain pieces. They withstand high temperatures and repeated use.

2. Plaster (Gypsum): A traditional choice, plaster molds are cost-effective and work well for simple shapes. However, they are brittle and less suitable for highly detailed designs.

3. Polyurethane Rubber: Known for its toughness, polyurethane molds are resistant to abrasion and chemicals, offering a longer lifespan for mass production.

4. Alginate: Used for quick, short-term molds, alginate is biodegradable and captures fine details but lacks durability for long-term use.

5. Latex Rubber: Flexible and affordable, latex molds are suitable for smaller projects but require multiple layers and longer curing times.

For the best results, consider the sculpture’s complexity, production scale, and budget when choosing a mold material. Combining materials, like using silicone for detail and plaster for support, can also enhance outcomes.
