The Next Bronze Age

Description:
Welcome to the next step in the evolution of metal clay:
BRONZclay™! BRONZclay provides an incredible artistic
range. And, because it’s bronze, it’s so affordable, it can be
used to sculpt large pieces and create specialized tools—it can
even be thrown on a potter’s wheel to shape bronze hollowware.
Available in generous 100- and 200-gram blocks, BRONZclay allows
the artist to experiment with how far (and big!) designs can go.
BRONZclay can be pinched,
rolled, sculpted, and manipulated. In its dried state, it’s
still highly flexible and easy to carve—an ideal canvas for
applying details and finishing touches prior
to firing. When fired in a kiln (See below), the binder
vaporizes, leaving a solid, pure bronze object that can be sawn,
shaped, drilled, sanded, patinaed or soldered using traditional
jewelry tools and techniques. This exciting medium offers a new
world of possibilities for jewelry-makers, artists and
sculptors. |
Firing BRONZclay
You will need to dry your BRONZclay™ piece thoroughly before firing to
prevent moisture in the clay from expanding and creating defects during
firing.
To dry the piece, gently place it on a warming surface such as a coffee
mug warmer or a vegetable dehydrator.
When dry, the clay will be leather-hard, making it flexible and amenable
to finishing touches such as filing, drilling, sanding and carving.
After firing, this work is more time-consuming, so take advantage of
this pre-fired stage to do as much of your detailed finishing work as
possible.
To reduce oxidation, the BRONZclay™ piece(s) must be surrounded by
activated carbon during firing. The coconut shell–based carbon produces
a natural bronze (terra cotta) color; the coal-based, acid-washed
carbon produces a colorful range of patinas.
To Fire BRONZclay™:
1) Spread 1" of activated carbon granules on the bottom of a stainless
steel firing pan
2) Place the piece on top of the layer; if firing two or more pieces,
leave at least 1/2" between pieces; leave more if the pieces are larger.
Note: Most kilns are cooler in the front near the door, so the front of
your firing pan will be cooler than the back
and sides. Compensate for this by placing pieces closer to the sides and
back of the firing container. If you’re using a top-loading kiln,
there’s no need to adjust.
3) Pour more activated carbon granules on top of the piece until the
container is full, making sure there is at least a 1/2" layer of
granules on top of the piece. If you are firing several pieces in
layers, make sure there is at least 1/2" of space between the vertical
layers as well.
4) Cover the firing pan with its lid and place it in the kiln on stilts
to allow good heat circulation.
Warning! The firing pan will be extremely hot; do not touch! Allow the
pan to cool completely before removing the lid. We recommend wearing
heat-resistant gloves welding gloves while removing the
firing pan.
5) The firing pan should be allowed to cool completely before removing
it from the kiln; however, if you need to use your kiln again right
away, you can move the pan to a heat-resistant surface (e.g.: a
soldering pad or ceramic tile) and allow it to cool there.
6) Once the firing pan and carbon have cooled, remove the BRONZclay™
pieces from the carbon bed and place them on a heat-resistant surface to
finish cooling. You can re-use the activated carbon until you notice it
starting to break down (broken grains and a sooty appearance). Note: If
there are no stones embedded in the piece, it can be quenched in water.
