Ancient Iron Making in India

The discovery of Agni (i.e., fire) has been very closely related with the process of human civilization and it has been worshipped during the Vedic period or even earlier. The havankund has been described as the open air labo-ratory of the Vedic people and they had gained ample know-ledge about the physics and chemistry offire. The beg-inning of pyrotechnology could be traced to the Vedic period when man worshipped Agni for blessings of metals like gold, silver, copper, iron, tin, lead and their alloys. The archaeological evidence has confirmed that iron technology began only during the late second mille-nnium BC and it has been proved to be of indigenous origin. The paper gives a brief review of the ancient Indian community associated with this craft, viz., Agarias and other tribes worshipping God `Asura'. They developed their own secret technology of iron smelting to produce iron and steel of excellent quality. Their practice of
charcoal iron smelting was considered to have stopped at least for the past one century but recent surveys have traced it to continue to be practiced in some parts of Madhya Pradesh, Eastern U. P. and Bihar. It has provided
an opportunity to study this ancient craft, its thermo-chemistry and process control as well as the details of the furnace construction and its operation. The high
level of skill in smelting sponge iron blooms and its refining to produce tonnes of iron is certified by the uniformity of composition of the corrosion resistant
iron used in the manufacture of some of the heaviest
ancient forgings existing in the country.
