Provides an incredible artistic range in metal clay. And, because it is bronze, it is also so economical that you can use it for large pieces-even sculptures-very affordably! Like its precious-metal counterparts, BRONZclay can be pinched, rolled, sculpted, cut or manipulated any way you like. Then fire it, and the binder burns away, leaving a solid, pure bronze object. Create jewelry, jewelry components, or custom-crafted specialized tools. You can even practice new techniques or design ideas using BRONZclay, then apply your new skills to precious metals.
