It is a mixture of micron sized bronze 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. Prometheus® Bronze Clay can be fired with most lab-created gemstones (cubic zirconias), pre-tested natural stones, glass beads, ceramic and porcelain. \u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cspan\u003eWhen the clay is fired in a kiln, the organic binder evaporates and burns away and you’re left with pure, solid bronze.
