Product Description
Prometheus Sunny Bronze Clay is a clay-like 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 Sunny 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. Anything you create with Prometheus Sunny Bronze Clay is a piece of art. Combine it with your imagination and let your fingers do the rest!
HOW TO FIRE
Prometheus Sunny Bronze clay can be fired on a single stage, or two-stage firing:
SINGLE STAGE:
- Preheat your kiln to 820°C/1500°F.
- Place your dried bronze piece onto stainless steel mesh, and into the kiln
- Wait for the kiln to heat back up to temperature, and fire for 30 minutes
- After 30 minutes, remove the piece and leave to cool on a heatproof surface, or quench in water (unless fireable gemstones have been used). Leave in pickling solution if any fire scale is left.
TWO STAGE (recommended):
- 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 820°C/1500°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 1 hour
- Once finished, remove the piece and leave to cool on a heatproof surface
This clay shrinks between 12-13% based on firing methods.

Gorgeous colour and fires fast
I've used Prometheus copper for a long time and decided to try this new brighter bronze as Prometheus clays have always fired successfully for me. This one was just as I was hoping. The 'rapid and low fire' means that I can fire a batch in around three hours with cooling between stages and every piece has come out successfully. It's a nice smooth texture and I can get very fine detail and tiny components from it. I rarely need to add water to the clay when working. It feels very hard and robust when dry and I can carve and work with it extensively without feeling it is fragile. It fires a gorgeous gold colour and easily takes a good shine - it's solid and hard once finished.
