Prometheus® syringe with 999 silver clay paste

Prometheus® 999 Silver Clay offers you a practical and efficient way to create pure silver jewelry that's stronger and more flexible. This clay doesn't require activated charcoal or complicated multi-stage firing processes.

Simple cooking:

Place your dried pieces on an oven rack at room temperature and follow one of these methods:

For rigid and stable parts

Oven at 570°C / 1058°F for 1 hour

Estimated shrinkage: 12%

For pieces you want to bend (such as rings or bracelets)

Oven at 700°C / 1292°F for 1 hour

Estimated shrinkage: 13%

Once firing is complete, you can remove your pieces even while they're still hot. You'll have 999 silver jewelry ready to be polished, enameled, or worn as is.
