Beágyazó gipsz Stonecast Blue 22,7 kg

STONECAST™ is a special application investment powder and has been developed specifically by SRS for stone casting or wax setting. Using STONECAST™ the Jewellery caster can set diamonds in the wax before casting rather than in the metal afterwards thus improving productivity.

STONECAST™ offers the following benefits to the jewellery caster:

• Preblended investment powder for stone casting - no need to make additions
• Provides heat shield for diamonds up to mould temperature of 630°C
• Setting time adjusted to give enough time for mixing and vacuuming without rushing
• Fluid slurry and flash setting to improve strength of moulds
• Improved surface finish for all metals including 24K Gold
