Traditionally the Gadwa, Gond and Dhurwa tribes of Kondagaon in Bastar region of Chattisgarh have been practising the Dhokra art with lost wax technique or hollow casting. It involves patterning a clay core intricately with wax wires and then coating it carefully with a mix of clay and hay. The wax covered clay core is put in the cauldron of molten metal with an opening/hole in the clay mixture, where the wax is subsequently melted off, and the space thus created is filled with metal- an alloy of copper, brass and tin which enters through the hole. The outer layer of clay is then chipped off and the metal icon is polished and finished as desired.
