A versatile, high HDT master pattern material for jewelry silicone molds and high visualization detailed prototypes of complex and fine designs.

Stunning surface finish and high definition for jewelry pieces prototyping and production with RTV/silicone molding.

Figure 4 JEWEL MASTER GRY is a versatile master pattern material for high volume jewelry RTV/silicone molds and for prototype/fit models. The material’s high heat deflection temperature (300°C) ensures compatibility with a range of silicones for creating molds used in jewelry casting production workflows.

This material also delivers exceptional precise surface quality for design and functional prototyping, as well as snap-fit and stone-in-place testing. Figure 4 JEWEL MASTER GRY meets biocompatibility standard ISO 10933-5 for cytotoxicity, making it safe for try-ons and fittings.
