In 1922, Indian archaeologists have discovered the ruins of the ancient city of Mohenjo-Daro. Five thousand years ago it was a great center for the amazing development of the Harappan culture of the era. Among the ruins were scattered alloy pieces of clay and other minerals that are in the distant past and solidifies into glass.
Analysis of the samples held in the University of Rome and in the laboratories of the National Research Council of Italy, showed that fusion occurred at a temperature of about 1500 degrees … It turns out that our history is simply moving in a spiral, and we remember only the last of its turnover.
