About BRONZclay

Bronze clay is made from an alloy of copper and tin. Bronze is a very strong metal and makes a wonderful medium for jewelry. Most people can wear bronze with no sensitivity. Bronze is similar to brass, but has a warmer color.

To fire bronze clay, the dry pieces are buried in a bed of carbon firing media inside of a stainless steel container. The media used is important, since some types of carbon do not allow sintering of the metal particles.

We offer 2 types of bronze clay, BRONZclay and FastFire BRONZclay. BRONZclay (also called Original BRONZclay), must be fired according to the thickness of the piece and can take up to 9 hours for sintering. FastFire BRONZclay is a formulation that fires in only 2 hours for most pieces.

The firing schedule used for both BRONZclay and FastFire BRONZclay depends on the kiln being used. Both types require a digitally controlled kiln to properly sinter the clay into a solid, dense metal form.
