For bronze casting, KKH makes use of cire-perdue, the lost-wax technique. A wax copy or other flammable original is provided with casting channels made of wax. A mould is created round the wax copy and is heated so that the wax runs out. The form is sintered and the molten bronze is poured into the gap inside the mould.

The bronze workshop uses the ceramic-shell technique for producing casting moulds instead of the traditional, compact mould made of plaster and clay. Shell moulds are easier to use and give a very precise image.

The bronze workshop is fully equipped for working with wax and moulds, firing, chasing and patinating. Casting takes place at the firm of Bergmans Konstgjuteri.
