Product Description
Prometheus Jeweller's Sterling White - Bronze Clay
Prometheus® Jeweller's Sterling White Bronze Clay is a claylike material which turns into pure, solid bronze when fired in a kiln. It is a mixture of micron sized bronze powder, water and organic binder. It can be formed by hand, rolled into a sheet or a rope. It can be moulded, textured, even turned on a potter's wheel. Prometheus® Bronze Clay can be fired with most lab-created gemstones (cubic zirconias), pre-tested natural stones, glass beads, ceramic and porcelain.
When the clay is fired in a kiln, the organic binder evaporates and burns away and you’re left with pure, solid bronze. Brush it, if needed pickle it to remove any fire-scale and finally polish.
You can create unique jewellery, ornaments, hollow ware, statutes, sculptures and many other decorative objects. Any thing you create with Prometheus® Bronze Clay is a piece of art. Combine it with your imagination and let your fingers do the rest!
This clay shrinks between 15%-16% based on firing methods.
HOW TO FIRE:
Prometheus® Jeweller's Sterling White Bronze Clay has a 2-stage firing:
- Place your dried piece(s) onto stainless steel mesh, and into a cold kiln
- Wait for the kiln to heat up to 500°C/932°F and fire for 15 minutes
- Once finished, remove the piece and leave to cool on a heatproof surface
- Preheat your kiln to 770º/1420°F
- Pour 3cm of activated carbon into a steel container, and place pieces at least 1.5cm apart
- Thoroughly cover with activated carbon, and place steel container inside the kiln
- Wait for the kiln to heat back up to temperature, and fire for 2 hours
- Once finished, remove the piece and leave to cool on a heatproof surface
Prometheus® Jeweller's Sterling White Bronze Clay can be combined with Prometheus Bronze Clay, Prometheus Copper Clay, and Prometheus Sunny Bronze and fired with the same firing schedule.
Annealing: If your pieces are thin and long, then it is recommended that you anneal your pieces in order to maintain high strength and malleability.
Available in 20g, 50g, 100g.

PROMETHEUS JEWELLER'S STERLING WHITE - BRONZE CLAY
Brilliant clay, easy to use, and thicker pieces fired perfectly in the kiln. I did find thinner filigree type pieces broke easily. Looks silver in daylight, takes on a very slight yellow hint indoors.

Prosthemus jewllers sterling white
I had no luck with this at all. Followed instructions to the letter but my pieces came out a crumbling mess. I tried again thinking my pieces were maybe not dry enough but the same thing happened. Thought this would be a cheaper alternative to silver, but I was very disappointed. Total waste of time and money . ****** Reply from MC Ltd; Hi Alison, sorry to hear you were struggling. This is one of the hardest metal clays to get right. It does require a few tests to find what temp and time works best in your kiln, the basic recommended firing schedule is not a fit-for-all and will most likely require tweaking as all kilns are different. Once you find the best firing temp and time it is a beautiful clay.

Prometheus sterling white bronze clay
I love this clay, it's very easy to use, takes textures very well and is one of the few white bronze clays that actually could pass for silver or pewter.
