Dhokra is non–ferrous metal casting using the lost-wax casting technique. This sort of metal casting has been used in India for over 4,000 years and is still used. Their technique of lost wax casting is named after their tribe, hence Dhokra metal casting. The tribe extends from Jharkhand to West Bengal and Orissa; members are distant cousins of the Chhattisgarh Dhokras.
