Dhokra (also spelt Dokra) 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.Dhokra Damar tribes are the main traditional metalsmiths of West Bengal and Odisha. Their technique of lost wax casting is named after their tribe, hence Dhokra metal casting. The tribe extends from Jharkhand to West Bengal and Odisha; members are distant cousins of the Chhattisgarh Dhokras. A few hundred years ago, the Dhokras of Central and Eastern India traveled south as far as Tamilnadu and north as far as Rajasthan and hence are now found all over India. Dhokra, or Dokra from Dwariapur and Bikna, West Bengal, is extremely popular. Recently Adilabad Dokra from Telangana got Geographical Indicator tag in 2018.
