Castaldo Jewelry Natural Molding Rubber has been the industry standard for more than 40 years and continues to be the best jewelry molding rubber available for lost wax jewelry casting.
- Castaldo White Label® the firmer of the two grades, has a high concentration of pure natural gum rubber, which makes it resilient and pliable, qualities that the experienced mold-maker values in his efforts to produce high-quality molds in the shortest reasonable time.
- Castaldo Gold Label® contains even more pure natural gum rubber, making it even softer and more pliable. Experienced mold-makers know that this compound’s superior qualities can save them substantially on labour costs when used for difficult molds containing undercuts, where a stiffer mold would break delicate wax patterns or would make their production impossible altogether.
- Castaldo Jewelry Mold Release Spray is a pure silicone oil in an aerosol which can be used in releasing wax patterns from rubber or metal molds.
