The earliest evidence of iron smelting predates the emergence of the Iron Age proper by several centuries.[2]

R. Tewari (2003) radiocarbon dated iron artifacts in Uttar Pradesh, including furnaces, tuyeres, and slag between c. 1800 and 1000 BCE. The use of iron and iron working was prevalent in the Central Ganga Plain and the Eastern Vindhyas from the early second millennium BCE.[3] The beginning of the use of iron has been traditionally associated with the eastward migration of the later Vedic people, who are also considered as an agency which revolutionised material culture particularly in eastern Uttar Pradesh and Bihar. Scholar Rakesh Tewari states that new finds and their dates suggest the need for a fresh review. According to him, the evidence corroborates the early use of iron in other areas of the country, and attests that India was indeed an independent centre for the development of the working of iron.[4][5]
