METHOD OF CASTING The most popular process of metal casting is called “Cire Perdue” or ‘lost-wax’ process. It is done in two ways. In the first way (solid) initially a wax model of the desired sculpture is prepared. Over a mould is made by plaster and surakhi. When it becomes hard, the wax is melted out and plaster mould is ready. Then the molten bronze is poured in this mould. After solidification of bronze, the mould is broken and the sculpture is finalized by chasing and furnishing. By the second way was hollow bronze casting is done initially in this method a clay model of desired sculpture is made and coated with layer of wax to produce all the details of the from. Afterwards, it is again covered with a thin layer of the fine clay. After being dried up. It is again repeated so that a thick outer shell is formed. This is called negative. When the negative is heated, the wax melts and comes out through the openings, leaving a space between clay model and its negative. Finally the molten liguid metal is poured to get the desired sculpture. After begin cooled, it gets hardened; the outer shell is broken. The figure is finally chased with a chisel and then polished. Dokra Casting or Lost Wax (Cire-Perdue) technique: 1. Making a clay core cover by firing in kiln. 2. Wrapping bee-wax around the core to get a replica. 3. Coating the replica with wet clay and then drying in sun. 4. Heating should melt the wax which flows out early. 5. Filling with metal. Cast in furnance and left to cast. 6. Breaking the mould to get a Dokra Artifact. ‘ i =a 416-17-DPSVK-11-Chapter08-Page02
