Castaldo Gold Label Natural Jewelry Molding Rubber-5 lb Roll

Castaldo USA has recently been sold to a company in the United Kingdom. All Castaldo products are now manufactured in the UK. Castaldo Gold Label Natural Mold Rubber is no longer available in Strips or Ready Cut (Pre-Cut) and will only be available in 5 lb Rolls.

CASTALDO® Gold Label contains even more pure natural gum rubber than Castaldo White Label, making it even softer and more pliable. Experienced mold-makers know that this compound’s superior qualities can save them substantially on labor costs when used for difficult molds containing undercuts, where a stiffer mold would break delicate wax patterns or would make their production impossible altogether.

• Vulcanize at 310°F for 15 minutes per 1/4" of mold frame thickness.
