Prometheus® Silver Clay 999 25g
Prometheus® Silver Clay 999 will give you the ability to design stronger and bendable jewels. It does not require activated carbon or multiple-steps firing. Just put your dried pieces into your kiln at room temperature on a kiln shelf and full ramp speed to 570°C/(1058°F) for 1 hour and the shrinkage will be 12%. If you would like to bend your fired pieces into bracelets or ring loops than fire your pieces from room temperature to 700°C/(1292°F) at full ramp for 1 hour and the shrinkage will be 13%. That's all... You can take out your fired pieces while still hot.
