One such sites is in puma punku , bolivia. Mystery of the pyramids is well known mystery ,In this Video Series we take a closer look at striking examples of advanced ancient technologies that were far ahead of their times. Some of these sophisticated ancient inventions were later re-invented by our modern society, but not all. There is no doubt ancient people possessed highly advanced knowledge in a number of areas... Standing at the center of the Quwwatul Mosque the Iron Pillar is one of Delhi’s most curious structures. Dating back to 4th century A.D., the pillar bears an inscription which states that it was erected as a flagstaff in honour of the Hindu God and in the memory of the Gupta King Chandragupta II (375-413). How the pillar moved to its present location remains a mystery. The pillar also highlights ancient India’s achievements in metallurgy. The pillar is made of 98 per cent wrought iron and has stood 1,600 years without rusting or decomposing.Iron pillar has avoided corrosion from the rains, winds and temperature fluctuations over the last 1600 years, not through a conscience effort or magical metallurgy technique on the parts of the pillar’s creators, but through the accidental formation of a “passive protective film.” Ninety eight percent pure wrought iron, the column is a absolute testament to the high level of skill achieved by ancient Indian ironsmiths. It would have had to been made using a coal heated furnace to even create a heat hot enough to achieve forge welding, where two or more pieces of metal were hammered together. Experts at the Indian Institute of Technology have resolved the mystery behind the 1,600-year-old iron pillar in Delhi, which has never corroded despite the capital’s harsh weather. Metallurgists at Kanpur IIT have discovered that a thin layer of “misawite“, a compound of iron, oxygen and hydrogen, has protected the cast iron pillar from rust. The protective film took form within three years after erection of the pillar and has been growing ever so slowly since then. After 1,600 years, the film has grown just one-twentieth of a millimeter thick. The protective film was formed catalytically by the presence of high amounts of phosphorous in the iron—as much as one per cent against less than 0.05 per cent in today’s iron. The high phosphorous content is a result of the unique iron-making process practiced by ancient Indians, who reduced iron ore into steel in one step by mixing it with charcoal. The Great Pyramid of Giza is perhaps one of the most incredible achievements of ancient man, one that our engineers and architects today would have a hard time replicating with the perfection and details the ancient Egyptians did. But when we see iron pillar in delhi this seems to be false. music - Transcend by Audionautix is licensed under a Creative Commons Attribution license ( Artist: Metaphysik by Kevin MacLeod is licensed under a Creative Commons Attribution license ( Source: Artist:
