Enjoy the direct design process of working with bronze metal clay! BRONZclay consists of 11% tin, 89% copper, water and non-toxic binding materials. The binding materials vaporize during the firing process, leaving a solid bronze object with a density 90% that of cast bronze. BRONZclay 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. 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 bronze hollowware.
