Hi Manpreet, Dhokra craft is one of the most admired works of Indian craftsmen. Dhokra Damar tribes are the traditional metalsmiths of West Bengal. Their technique of lost wax casting is named after this tribe, hence Dhokra metal casting. The tribe extends from Bihar to West Bengal and Orissa members are distant cousins of the Madhya Pradesh Dhokras. A few hundred years ago the Dhokras of Central and Eastern India traveled south as far as Kerala and north as far as Rajasthan and hence are now found all over India. Besides India, this lost wax technique for casting of copper based alloys has also been found in China, Egypt, Malaysia, Nigeria, Central America and other places. There are two main processes of lost wax casting, namely solid casting, and hollow casting.
Hi Manpreet.....indeed its a nice post from your part. Dhokra jewelery is personally my favorite and they are heavy enough to suit my dance costumes quite often....There are two main processes of lost wax casting: solid casting, and hollow casting. While the former is predominant in the south of India the latter is more common in Central and Eastern India. Solid casting does not use a clay core. On the contrary it uses a solid piece of wax to create the mould. However hollow casting is the more traditional method and uses the clay core. The first task in the lost wax hollow casting process consists of developing a clay core. This clay core bears roughly the shape of the final cast image. Next, the clay core is covered by a layer of wax, resin from the tree and nut oil. The wax is then shaped and carved in all its finer details of design and decorations. It is then covered with layers of clay. Drain ducts are left for the wax, which melts away when the clay is cooked. The next step is to replace the wax by the molten metal. The liquid metal is poured and the mould and takes the same shape as the wax. The outer layer of clay is then chipped off and the metal icon is polished and finished as desired.
