Lost Wax Technique
Lost Wax Technique of making bronze statues is an ancient technique still prevalent in many parts of the country particularly the Himachal Pradesh, Odisha, Bihar, Madhya Pradesh and West Bengal. In each region, a slightly different technique is used. Under this technique, the beewax is first melted over an open fire and then strained through a fine cloth into cold water. The bee wax immediately solidifies and it is now passed thru a pharni, so that the wax comes out of it in the shape of noodle like wires. These wax wires are now used to make a shape of the entire image first. After that, this image is covered with a paste of clay, sand and other materials such as cow dung. On one side, an opening is kept. When it becomes dry, the wax was heated and the molten wax was drained out through a tiny hole. The hollow mould thus created was filled with molten metal which took the original shape of the object.
