COPPRclay™

Kiln Fire: See our "TechSpecs" below for instructions.

COPPRclay consists of pure copper, water and non-toxic binding materials. The binding materials vaporize completely during the kiln-firing process, leaving a solid copper piece with a density over 95% that of cast copper. All copper used to make COPPRclay is recycled!

COPPRclay can be pinched, rolled, sculpted and manipulated. In its dried
state, it's still highly flexible and easy to carve—ideal for applying details and finishing touches prior to firing. And because it’s pure copper, it’s great for applying enamels.

Rich in color, full of history and representing an incredible combination of art and skill, new COPPRclay offers a world of possibilities to jewelers!

And, because COPPRclay 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 copper hollowware. Available in generous 30-gram, 100-gram and 200-gram blocks, COPPRclay allows the artist to experiment with how far (and big!) designs can go! And because COPPRclay is pure copper, it’s great for jewelers and sculptors who enjoy applying enamels.

Firing Instructions


Phase 1 (open-shelf fire)
  • For pieces 3mm thick or less: Place the piece directly on the firing shelf. Ramp at 500°F/hour (278°C/hour) then hold at 560°F (293°C) for 15 minutes.
  • For pieces thicker than 3mm: Place the piece directly on the firing shelf. Ramp at 200°F/hour (93°C/hour) then hold at 560°F (293°C) for 15 minutes.
Phase 2 (sintering)
  • Regardless of thickness: Embed the piece in coconut shell– based activated carbon inside a firing pan. Ramp at full speed to 1750°F (954°C) and hold for 3-1/2 hours.
  • Allow the piece to cool naturally inside the kiln.


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
