Eco-Resin & Stone Moulds for Art and Functional Casting

Moulds for eco-resin, Jesmonite, and gypsum casting are designed to hold fine surface detail over multiple pours without degrading. The two most common mould materials for these applications are silicone and plastic (ABS or polypropylene). Each offers a different balance of detail reproduction, longevity, and release performance.

Silicone moulds are the default choice for resin art because their non-stick surface releases fully cured resin without a release agent, and they reproduce fine surface texture well. For production use, higher-durometer silicone (more rigid) retains dimensional accuracy longer than ultra-soft silicone, which can distort under the weight of a large pour.

Plastic moulds are suitable for Jesmonite and gypsum but usually require a release agent such as a furniture polish or petroleum jelly. They are generally more rigid and dimensionally consistent than silicone, which is useful for flat-bottomed forms like coasters and trays that need to be perfectly level. Always cure in a level environment and mix your resin or mineral compound according to the manufacturer's exact ratios — incorrect ratios are the most common cause of soft or tacky finished pieces.
