Prometheus Silver Clay 999 Paste Type 20g
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.
