PMC STERLING .925
To transform the dry clay into solid sterling silver, a short 2-stage firing process is used. The first phase (30 minutes at 1000ºF / 538°C on an open kiln shelf) burns away the organic binder. The second phase is a 30 minute carbon firing at 1500ºF / 815°C to sinter the clay into a solid sterling silver object. Check out our Gemstone Firing Guide for details on firing a specific stone.
