R. Tewari (2003) radiocarbon dated iron artefacts in Uttar Pradesh, including furnaces, tuyeres and slag between c. 1800 and 1000 BCE. Iron using and iron working was prevalent in the Central Ganga Plain and the Eastern Vindhyas from the early second millennium BCE. 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.
^The archaeological term "Iron Age" began to be commonly applied to Indian prehistory in the 1960s (N. R. Banerjee, The Iron Age in India, 1965).
Note that the use of "Iron Age" for the Kali Yuga is earlier but unrelated, referencing references the mythological "Ages of Man" of Hesiod.
