Art Clay Copper

Art Clay Copper is a clay material that can make a wide range of pieces such as jewelry, craft designs, and objects like sculptures and models. Art Clay Copper can be fired in an electric kiln without using carbon, with the resulting fired piece being 100% pure copper. Art Clay Copper is a water-based clay, and dries naturally in the air. To avoid drying, when starting your piece, use the amount needed to make your desired piece, and store the rest in a clay hydrator.

Product Tips

After opening your package of clay, the surface of Art Clay Copper will naturally start oxidizing and the color will darken if left in the air. If you see a darkened surface, scrape off the darkened layer and use the internal clay to make your piece.

After firing in the kiln, the surface layer of the piece will oxidize similar to soldered sterling silver. You will need to take away the oxidized surface with pickling solution such as powder-form pickling compound to obtain a pure copper color.

After firing, take out the fired piece with tweezers or tongs from the kiln, and quench immediately with water, so that most of the oxidized layer which occurs during firing will peel off. Work in a well ventilated area. Wear safety glasses. For your safety, immediately place a fiber cloth over the piece. The oxidized layer on the surface will fracture and at times small pieces can fly into the air.

To make paste, apply a small amount of distilled water to some soft clay or the ground powder of dry clay, and blend well while crushing and blending in any hard pieces. Use this paste for filling up any cracks in the dried clay of your piece, and for joining clay parts.

After firing and the oxidized surface is removed, the piece is now pure copper. You can enjoy its beautiful metal luster by polishing with a metal brush, burnisher, polishing points and a tumbler.
