This is an art of metal practiced by tribals of west Bengal and Orissa. The metal used is usually brass. The technique is basically a low wax casting. This technique is ages old going back to the Indus Valley Civilization.
The name for this technique comes from the Dhokra Damar Tribes in the regions of Orissa. In this technique, the core is developed using clay or wax. Then it is covered with wax and the figure is engraved on it and then covered with layer after layer of clay.
The molten metal is then poured. The wax gets melted and then comes out from the holes meant for this purpose.
