This is the new copper clay that I've been itching to try. It's much more affordable than the silver clay - about $20 for 100 grams, versus $90 for the silver. It's always appeared fussier to me because it has to be fired in a near oxygen-free environment to avoid the nasty oxidation that copper tends to get. Therefore, it gets fired in a pan with activated carbon. So, I ordered all the necessary equipment and will start playing with it soon. I should be able to make some large pieces that are very reasonably priced. Stay tuned!
