COPPRclay consists of pure copper, water and non-toxic binding materials. The binding materials will vaporize during the firing process, leaving it with a density 95% that of cast copper. COPPRclay can be added to a variety of media, including glass, ceramics, porcelain and polymer clay. It can be rolled, sculpted, stamped, sanded, burnished, filed, engraved, drilled and pre-polished, before and after firing.
COPPRclay allows you to create an amazing variety of unique jewelry and one-of-a-kind beads with just a few tools. Its economic price compared to precious metal clays allows you to create large pieces, too, including handmade tools. You can even use it on a potter's wheel to shape copper hollowware. There are a few tricks to it, though ... We strongly recommend that you take some time to get familiar with the product before beginning your first project.
Other things we should mention:
COPPRclay must be fired in a kiln.
COPPRclay shrinks a total of approximately 20% from package to finished product. When you create your pieces, keep this in mind.
To recycle every usable scrap, and keep it at a good consistency, use small plastic screw-top containers (#69-132). These containers provide space for the clay and space for a damp sponge, separated by a perforated or breathable layer.
If you also work with Art Clay Silver, your ACS tools and work surfaces must be kept separate from the tools and surfaces that you use with COPPRclay. The materials do not work well together, and you will get some unwanted results if you use the same tools and work surfaces for both.
Like other clays, COPPRclay can be formed, molded, sculpted and shaped using your own hands. 20% shrinkage when fired. 100grams. Inexpensive way to get started with metal clay. To reduce oxidation, the clay must be surrounded by activated coconut-shell based carbon during firing. Do not use coal-based carbon on COPPRclay.
I absolutely love this stuff. It may take an extra step in firing, but it's worth it to be able to experiment with large designs or techniques I wouldn't want to gamble with silver clay. I've drilled fired pieces and they appear to be sintered all the way
