Prometheus® Bronze Clay 50gr.
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 firescale 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!
For firing PBC® you have 3 choices. As Prometheus® we recommend the Carbon Method:
CARBON METHOD
This is a 2-step-method.
Step.1 Place the dried piece (or pieces) on a stainless
steel mesh and put it in to the cold kiln and let it raise to 500°C/ 932°F or put
it on a kitchen stove. Fire it for 15 minutes, take it on to a fire proof
surface and let it cool down.
Step.2 Put approximately 3 cm. of activated carbon to the
bottom of a steel container. Place the pieces with at least 1.5 cm space
between each other and fill the container with activated carbon, close it and
put it into the preheated kiln to 820°C/1500°F. Let the kiln raise to the target temperature
again and fire it for 60 minutes. When the firing is completed, either leave it
to cool down in the kiln or, carefully take it out and leave it on a heat
isolated surface until it is cold enough to take your pieces out.
OPEN SHELF FIRING
Place the dried piece (or pieces) on a stainless steel mesh and put it in
to the pre-heated kiln to 820°C/1500°F.* Wait for the kiln to raise up to its target temperature again, then
start timing your firing for 30 minutes.
When the firing is completed, take out the piece, put it on a heat proof
surface and wait for it to cool down or much better, quench it in water while
it is hot.** Most of the fire scale will fall of the piece. If any left, leave
it in hot pickling solution for some time then rinse with water.
* Most kilns are cooler near
the front door, so put them close to the back of the heating chamber.
** Beware of water vapour.
TORCH FIRING
Place the dried piece on a stainless steel mesh. Put the mesh on a fiber
brick or a thick construction brick. First start heating the piece very slowly until you see it producing a
flame like candle and smoke which means that the binder is burning. Once the
flame and smoke disappear, start heating the piece with full power until you
achieve orange-red colour and continue firing at least 5-10 minutes carefully
observing that the piece keeps this orange-red colour during whole time. Avoid melting. After firing is completed, either
leave it to cool down or quench in water. Leave the fired piece in hot Picklean®
solution to get rid of any fire scale if any left.
