Combine the material with your imagination, and let your fingers do the rest! \u003c\/p\u003e\n\u003cp\u003eIt is a mixture of micron sized copper powder, water, and organic binder. It can be formed by hand, rolled into a sheet or a rope. It can be moulded, textured, even turned on a potter's wheel. When Prometheus Copper Clay is fired in a kiln, the organic binder evaporates, burns away and you're left with pure, solid copper. Brush it, if needed pickle it, to remove any fire scale, and finally polish. \u003c\/p\u003e\n\u003cp\u003ePrometheus® Copper Clay can be fired with most lab-created gemstones (cubic zirconias), pre-tested natural stones, glass beads, ceramic porcelain and Prometheus® Copper Clay .
