How to achieve positive firing outcomes
Prometheus Jewellers 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 an organic binder.
Prometheus Jewellers Sterling WHITE 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 Jewellers Sterling WHITE 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 Jewellers Sterling WHITE 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) 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.
White bronze clays are very popular but can be even more challenging to fire than other base metal clays. The following firing schedule (using a Paragon SC2 kiln) was recommended by a regular
Prometheus Jewellers Sterling WHITE Bronze Clay user.
Please be aware that it may not work with your kiln and testing using the manufacturers firing schedule is always our first recommendation.
