The Gupta era (fourth and fifth centuries AD) in India witnessed spectacular iron technology in Ujjain, where big iron objects were forged in special furnaces. The fourth century iron pillar, now at Meharauli, Delhi, and the tenth century Dhar pillar (43'8" high, the highest in the world) of king Bhoja are unique examples of hot forging of wrought iron.
