Prometheus Sunny Bronze Clay Syringe 10g with 3 Nozzle (S M L )     

 How to achieve positive firing outcomes 

Use this syringe to embellish and enhance pieces made with Prometheus Sunny Bronze Clay. Achieve a beautiful golden metal finish with Prometheus Sunny Bronze Clay. Fired Prometheus Sunny Bronze Clay is a lighter, more radiant version of original Prometheus Bronze Clay. It bears a close resemblance in colour to 9ct Yellow Gold.

Prometheus Sunny 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 an organic binder. 

Prometheus Sunny Bronze Clay can be formed by hand, rolled into a sheet or made into a rope. It can be moulded, textured and 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, glass beads, ceramic and porcelain. 

When the clay is fired in a kiln, the organic binder evaporates and burns away. What remains is pure, solid bronze. 

If there is any fire scale left on a piece after firing, it can be placed in a pickle solution to remove it. The solid bronze piece can then be wire brushed and polished.

Create unique jewellery, ornaments, hollow ware, statutes, sculptures and many other decorative objects. 

Use your imagination and let your fingers do the rest!

Prometheus Bronze Clay can be fired in a single or two-stage firing.

SINGLE STAGE    Prometheus Bronze Clay Conventional Firing

Preheat your kiln to 820ºC

Place your dried bronze piece onto stainless steel mesh and into the kiln

Wait for the kiln to reach temperature and fire for 30 minutes

After 30 minutes, remove the piece and leave to cool on a heatproof surface. Alternatively quench in water BUT NOT if fireable gemstones or glass have been included in your design.

TWO STAGE (recommended, most successful method) will achieve a brighter golden finish   Prometheus Bronze Clay Activated Carbon Firing

Place your dried piece(s) onto stainless steel mesh, and into a kiln at room temperature

Wait for the kiln to heat up to 500°C and fire for 15 minutes

Once finished, remove the piece and leave to cool on a heatproof surface

Preheat your kiln to 820º

Pour 3cm of activated carbon into a stainless steel container and position pieces at least 1.5cm apart.

Cover with activated carbon and place steel container inside the heated kiln

Wait for the kiln to heat back up to 820º and fire for 60 minutes

After 60 minutes, remove the piece and leave to cool on a heatproof surface

HAND HELD TORCH FIRING Prometheus Sunny Bronze Clay can be torch fired (see cautionary note below)     Prometheus Bronze Clay Torch Firing

When Prometheus Bronze Clay  was first introduced, the hand held torch firing method was widely recommend. For valid reasons, it is no longer the manufacturers recommended firing method.  

However, it must be mentioned that with perseverance, small pieces of Prometheus Bronze (maximum 2.5cm and 25mm thickness) can be successfully fired with a handheld gas torch.

Prometheus® Jeweller's Sterling White Bronze Clay can be combined with Prometheus Bronze Clay and Prometheus Copper Clay and fired using the same kiln firing schedule.

Annealing: If your combined pieces are thin and long, then it is recommended that you anneal your pieces in order to maintain high strength and malleability.
Annealing.  Heat your pieces at 565°C for 5 minutes and quench in water.
