FASTfire BRONZclay™ is a non-toxic metal clay product used by jewelry artists and craftspeople to create one-of-a kind and small run jewelry, models, prototypes, sculpture and decorative items.

Just about anything you can image can be sculpted, formed or molded using the moist clay. Objects are fired in a table top kiln to transform them into solid bronze metal.

Gemstones and some other items can be embedded in the wet clay and fired together. After firing, the metal is polished and finished. The final product is actual metal because the clay is made of real metal powders.

FASTfire BRONZclay is so affordable, it can be used to sculpt large pieces and create specialized tools—it can even be thrown on a potter's wheel to shape bronze hollowware. Available in 30, 100 and 200 gram blocks, FASTfire BRONZclay allows the artist to experiment with how far (and big!) designs can go.

FASTfire BRONZclay can be pinched, rolled, sculpted and manipulated. In its dried state, it's still highly flexible and easy to carve—an ideal canvas for applying details and finishing touches prior to firing. When fired in a kiln (as outlined on this website), the binder vaporizes, leaving a solid, pure bronze object that can be sawn, shaped, drilled, sanded, patina-ed or soldered using traditional jewelry tools and techniques. This exciting medium offers a new world of possibilities for jewelry makers, artists and sculptors.
