A recent study has revealed a surprising fact about the weapons used in Bronze Age. The study claims that the most of the iron used in weaponry and artifacts during the Bronze Age came from outside world. That means the iron tools dating back to the Bronze Age had extraterrestrial origins. The new research was led Albert Jambon from the National Center for Scientific Research (CNRS).

Actually, iron tools were mostly used in Iron Age when people became aware of the smelting process. But some iron tools or artifacts were also found to be used during the Bronze Age. But at that time, it was much harder to get the iron tools and work with it because most of the metal was locked in ore and needed to be smelted at very high temperatures. But according to the researchers, people were not capable of using smelting technique during the Bronze Age.

So, where do this Bronze Age iron artifacts and weapons come from? Either it was from a meteorite or any other source? So, to get answer to all these questions, French scientist Jambon used geochemical analyses to know whether the Bronze Age iron samples were of terrestrial or extraterrestrial origin. The bronze age artifacts and weapons that he studied include King Tut’s dagger, a bracelet and headrest belonging to the Egyptian king in 1350 BCE, a dagger from Alaca Höyük (Turkey, −2500 BCE), “beads from Gerzeh (Egypt, −3200 BCE), axes from Syria and China dating back to about 1400 BCE, a Syrian pendant from 2300 BCE and many more.

With the help of the portable X-ray fluorescence spectrometer, an instrument that can determine the elements that a rock or metal is made up of without damaging the target, Jambon figured out which iron metals were produced through smelting of ore and which were having meteoric origin. Earthy iron ore must be first reduced by removing oxygen present inside and then it can be used to make weapons and artifacts. But meteorite irons are premade iron because they are already in metallic state and can be used without undergoing smelting. When planets are formed, all nickel drifts towards the molten iron core.

As meteorites are mostly formed from breaking or shattering of planets, they contain a large amount of nickel and cobalt. In his research, Jambon also found many samples containing nickel and cobalt, and from this, he concluded that iron tools of Bronze had cosmic origins and the iron that was used was meteoric iron. The Bronze Age began around 2300 BC, and the Iron Age started roughly around 1200 BC.
