Few tourists today care about the history of this column. And very little does he know that it is a great mystery for historians, archaeologists, metallurgists, etc., which AC Clark spoke of in the 80s.

The column is currently located in Delhi (India). However, it is believed that it was originally located somewhere in the Madhya Pradesh area as part of a building that existed there several thousand years ago. Some sources state that its original place was in the locality of Shimla.

During my last visit to the Indian Institute of Advanced Studies, I attended a series of lectures on the Iron Pillar, which were presented by a visiting expert, a well-known metallurgist, Professor R. Balasubramaniam of the IIT in Kanpur.

Let's recall some well-known facts. The column is 7,3 meters high, with 1 meter being underground. The diameter of the column is 48 cm at the base and tapers to 29 cm at the top - just below the head. Its weight is 6,5 tons. It is formed by compressing metals at high temperatures. And that's about all, with most agreeing. The rest is filled with speculation and controversy. To the questions: "Who had the pillar built, when did it happen and for what purpose? ” it is not possible to give a clear answer at present. Likewise, the mystery is the inscriptions, which were apparently additionally engraved into the column. According to them, we can certainly have a period of time, but it is certainly not possible to say that they were created at the same time as the column. The biggest mystery is the fact that the column practically does not rust.

Even if we admit that in his time he was probably not the only one of his kind, the fact remains that he is definitely one of the few that has survived to this day. Whatever time frame we assign to its origin (the official literature states 375 to 413 AD), then it is a completely unique phenomenon in terms of production processes and chemical composition.

During the last century, samples were taken from the column to examine its composition and production technology. The tests were carried out by the National Metallurgical Laboratory (NML) in Jamshedpur, the center of the Indian steel industry in Jharkhand, a state formed in 2000 in southern Bihar.

It has been found that the oxide coating on the surface has a thickness of 0,5 to 0,6 mm and consists of a mixture of iron oxides, quartz and limestone from dust deposits. The average chemical composition of the metal samples from different column sites is: 0,23% carbon, 0,07% manganese, 0,07% silicon, 0,18% phosphorus, traces of sulfur, traces of chromium, 0,05% nickel and 0,03% copper; the rest is iron. This is definitely not meteoric iron, which is characterized by a higher proportion of nickel and the presence of platinum group metals, especially iridium. This is technical iron - carbon steel with increased phosphorus content.

Still, the definitive answer to the question of why the iron column in Delhi does not corrode is still unknown.
