BRONZclay Brand Bronze Metal Clay

Additional Photos:


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

In comparison to Gold and Silver clays, BRONZclay is extremely affordable. Available in generous 30 gram, 100 gram, 200 gram and 1 kilogram blocks, BRONZclay allows the artist to experiment with how far (and big!) designs can go.

Carbon Firing/Kiln Temperature: 1500-1550°F
Hold Time: 3 hours minimum, according to thickness
Open-Air Firing Option: Original testing done by Martha Biggar
BRONZclay can be fired openly on a kiln shelf and quenched afterward. Firing time is significantly reduced, and quenching removes much of the firescale that may form.
Please note: This optional technique has been tested on pieces about four cards thick and 2" in diameter. To start, it is recommended that you fire on piece at a time to gauge how your kiln performs and adjust the time and temperature settings needed for the pieces you fire. Also note that multiple pieces require more time to quench; this can increase the formation of firescale during the process.
Kiln Temperature: 1540°F
Hold Time: 30 minutes
Shrinkage: 17-20%
