Bronze Clay is easy to use and costs much less than silver clay. Sculpt and Fire this clay and all that will remain is a beautiful bronze metal piece. It is available in generous 30 gram, 100 gram and 200-gram blocks. BRONZclay can be pinched, rolled, sculpted and manipulated just like any other modeling clay. In its dried state, it's still highly flexible and easy to carve, which makes it an ideal canvas for applying details and finishing touches prior to firing.
