Iron Pillar

Anything made of iron will rust after some time. But the iron pillar near the Qutb Minar in Delhi has been exposed to the elements for 1600 years and shows no trace of rust! The pillar, which chemical analysis has shown to be 99.72 per cent iron, is one of the marvels of the world. Even a modern steel mill would be hard put to produce a pillar of this sort. The ancient metallurgists knew the technique of making iron rust-proof and the secret, unfortunately, has died with them. The pillar which is estimated to weigh six tonnes is a solid piece and has no joints. It is about 7.3 m (24 ft.) in height.
