Description
Castaldo® Gold Label® jewelry molding rubber contains even more pure natural gum rubber than Castaldo White Label, making it exceptionally soft and pliable. Experienced mold-makers rely on this compound's superior flexibility for difficult molds with undercuts, where a stiffer rubber would break delicate wax patterns or make production impossible. The added pliability can translate directly into reduced labor costs on challenging pieces.
Available in 5 lb boxes in your choice of Strips or Ready Cut (Pre-Cut) format to suit your workflow.
