Cyprus Copper Clay is an excellent base metal clay medium for jewellery, crafts, sculpture and models. Offered in lump (wet) form, this clay is water-based, air dries and fires to .999 pure copper. Economical, easy to form, fire and finish, the fired clay presents as beautiful on its own or as the perfect platform for enamelling projects. In its greenware state, the clay is slightly flexible and carves easily.

This clay shrinks approximately 20%

Coconut Carbon is recommended for firing Cyprus Copper Clay, however Charcoal Carbon will also produce successful results.

** PLEASE NOTE ** - Magic Carbon is not recommended for use with Cyprus Copper Clay as it may complicate the use of embeddables, bezel settings and repairs, causing an increased or uneven shrink rate. It may also increase the shrink rate of the clay. We recommend creating a small test piece following the schedule before committing to firing complex work.


Two stage schedule

Phase 1

- Preheat kiln to 343ºC / 650ºF

- Option 1: Arrange dried pieces on a stainless steel mesh shelf on kiln posts for air circulation. Additional pieces can be stacked using more mesh separated with kiln posts.

(Please note: A slower phase 1 is needed for any piece that has areas that are 3mm (12 cards) thick or thicker. Ramp 149ºC / 300ºF / hour to 315ºC / 600ºF and hold for 15 minutes.)

- Option 2: The greenware can be placed on top of 1” of activated carbon in a steel firing container. Do not add activated carbon on top of the greenware for the phase 1 firing.

- Preheat kiln to to 343ºC / 650ºF and hold for 30 minutes.

Phase 2

Full ramp to 871ºC / 1600ºF and hold for 3 hours.

Once the pieces have cooled enough to handle from phase 1, gently transfer the work to a kiln firing tin that has at least 1” of activated carbon in the bottom.

Arrange the pieces with at least 1/2” of space between them. Cover all pieces with at least 1” of activated carbon. Additional work can be added in layers as long as there is 1” of activated carbon above and below each piece. Fire with a slotted lid or lid ajar. Do not cover firing tin completely.
