COPPRclay™

Kiln Fire

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

This product is made of 100% pure copper. COPPRclay shrinks about 20% of its original size during sintering. The density of fired COPPRclay is about 90% of cast copper. When properly sintered, COPPRclay can be bent and formed. Copper is a very soft metal and is easy to form, drill, saw and manipulate. This clay, when fired in a kiln, burns the binder away, leaving a solid, pure copper object.

Firing Instructions

Open-Air Firing Option: Original testing done by Martha Biggar
COPPRclay 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: 1750°F
Hold Time: 30 minutes
