The researchers found that the artisans, who lived 2,000 years ago, used some kind of ancient technology of thin metal films on statues and other items that surpasses today's standards to produce DVD, solar panels, electronic devices and other items.
This is an extraordinary discovery, published in the journal «Accounts of Chemical Research», refers to the "high level of competence of the artisans of the ancient period, who were able to produce items of a quality that can not be beat in those days, and which has not yet reached the advanced technology," write Scientists from the American Chemical Society under the direction of Gabriel Maria Ingo, who made the discovery.
Gilding and silvering — this is a long-known processes, which are based on the use of mercury, and were used in ancient times to cover items such as jewelry, statues and amulets with thin layers of gold or silver. Although they are most often used for decoration, they are sometimes used fraudulent purposes, to give the appearance of gold or silver less valuable metals.
From a technological point of view, the ancient masters 2,000 years ago in some unknown way it was possible to make these metal coating is incredibly thin, tight-fitting and to take any form, thus saving precious metals and improved durability — and our modern technology is not yet able to reach this level perfection.
It is obvious that without any knowledge of the chemical and physical processes, the ancient masters systematically manipulated the metals to produce extraordinary results. They have developed a set of techniques, including the use of mercury as an adhesive, to cover items thin films of precious metals.
This finding suggests that in the past some unknown way people with extremely good understanding of advanced technological concepts and processes, which can not yet be explained to our current level of data.
Another example of ancient technology can serve as a famous 2000-year-old Antikythera Mechanism — Metal device, consisting of a complex series of gears, which, according to the researchers, was used to calculate the positions of celestial bodies. Also The Baghdad Battery — A clay pot, encompassing copper cylinder with an iron rod in the center, which is, most likely, an early form of electric battery.
The level of technological sophistication in this case is striking for the period of two thousand years ago, and raises a lot of questions about where and how the people of the time it is knowledge.
