Iron Used During Bronze Age Was Not From Our Planet

Iron Used During Bronze Age Was Not From Our Planet”

The hiccups were that most of the iron was stacked in the ores and an exceedingly high temperature was required to smelt them - both these factors were beyond the technological capacity of that time. He used geochemical analyses in order to make a difference between metals from Earth and extraterrestrial metals used in a lot of artifacts from around the world originating from the Bronze Age. In fact, all the iron tools that belong to the Bronze Age have unearthly origins. By studying the ratios of iron, cobalt and nickel found within the artefacts, researchers created a system to differentiate iron produced through smelting of ore, and "pre-made" iron of meteoric origin. Using this, Jambon could tell from the iron's impurities whether the metal in the relics came from meteorites or was naturally occurring on Earth. On unusual occasions, iron tools and weapons have been found over the years, which date back to the Bronze Age. However, using it as a metal for object-making requires smelting, and a number of recorded iron artifacts from the time period-such as King Tutankhamun's dagger-predate the time when mankind was known to have such technology.

In a new study, Albert Jambon, from the University Pierre and Marie Curie, surveyed Bronze Age artifacts using portable X-ray fluorescence scanner.

A weapon as legendary as the dagger of King Tutankhamun needs an epic backstory, and previous year X-ray analysis showed that the iron in the ancient blade had come from meteorites.

Meteoroids that break off a celestial body can be composed of core materials, meaning they're packed with iron, nickel, and cobalt. "When large celestial bodies like our planet are forming, almost all nickel drifts towards the molten iron core", write the study's authors, indicating that mining techniques common during the Bronze Age would not have gone down far enough to extract significant quantities of nickel or iron.

The Bronze Age and Metal Ages in particular are of fundamental importance to the humanity and life that we live in today, as many things wouldn't be possible in the world as we know it if our ancestors hadn't move on from the Stone Age. Iron compounds from terrestrial ores, on the other hand, need to undergo processes that would remove the oxygen to produce the desired metal. Some objects that they studied included "beads from Gerzeh" which originated from Egypt around 3200 BCE, a dagger from Alaca Hoyuk, which originated from Turkey around 2500 years BCE, and a pendant from Umm el-Marra, which originated from about 2300 years BCE from Syria. The metal state of meteoric iron may also explain why it was used in the Bronze Age.

In the past, some experts have suggested that nickel-laden iron alloys may have come from terrestrial ores.
