Art Clay Bronze
Art Clay Bronze is a clay material to make a wide range of pieces such as jewelry, craft designs, and objects like sculptures and models. Art Clay Bronze must be fired in an activated carbon under reducing atmosphere using a programmable electric kiln, with the resulting fired piece being solid alloy.
Bronze ratio before firing: 90% (Rest of 10% is Binder and Water)
Bronze purity after firing: over 99.5%
Shrinkage: Approx.10%-13% in length
Art Clay Bronze 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.
Work in a well ventilated area. Wear safety glasses.
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 opening your package of clay, the surface of Art Clay Bronze 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.
You can enjoy its beautiful metal luster by polishing with a metal brush, burnisher, polishing points and a tumbler.
