Answer 1

Answer:

In Delhi, near Qutub Minar in Mehrauh, an iron pillar is situated which is constructed by ironsmith around 400 BC. This iron pillar is 8 m high and its weight is 6 ton. The pillar is protected even after centuries and it is not rusted. This shows that our ancestors had developed a technique to prevent rusting.

Researches shows that a layer of iron oxide is present on its surface. They had mixed phosphorous at the time of its formation. It had been painted by mixture of different substances and was heated strongly. Apart from Delhi, Sun temple in Konark, Odissa; Mukambika temple in Kollur in Karnataka, Dhar in Madhya Pradesh etc., are also the examples of ancient metal work.
