45g OneFire Sterling PMC

PMC OneFire Sterling - PMC OneFire Sterling is stronger than all fine silver versions of silver clay (99.9%) but has a higher purity than standard PMC Sterling 

Kiln fire at 870 - 900°C for one hour 

 
PMC OneFire Sterling - cannot be fired with a handheld torch.

The clay is ready to use straight from the pack. The clay is grey in colour but this will transform into a bright, white silver once fired and polished. Use Badger Balm or a little olive oil as a release agent for your hands, texture mats and plates. There is no need to use a release agent for your spacers, roller, work surface or moulds.

The dense nature of the clay means that it requires a little longer to dry compared to PMC3 or PMC Flex. 

Dry items can be placed in a cold or preheated kiln. Place on a porous kiln shelf and insert into the cold/preheated kiln. There is no need to use carbon. 3D items can be supported on some kiln pillow.

Firing schedule: Full ramp to 900C and hold for one hour. Approx. shrink rate is 15%.

Once fired, items will look grey in colour. Quench in water
