|According to researchers, ancient metalworkers hunted for iron from meteorites to create highly prized weapons before they could extract the metal from the earth. In 2016 X-ray scans on a dagger from Tutankhamun's tomb were made to determine what it was made from. Research indicates that before the very first kilns for smelting iron ore emerged around 3,200 years ago, all iron was crafted from meteorites.|
|Most meteorites that collide into the earth contain high levels of nickel or cobalt. Tutankhamun’s dagger was made with iron containing nearly 11 percent nickel and traces of cobalt.The oldest-known furnace for smelting iron ore is at Tell Hammeh in Jordan and dates to about 930 B.C. During the Bronze Age iron, because it could not be smelted, was valued at ten times the price of gold. As the Iron Age advanced, the price dropped rapidly allowing for a series of important discoveries using the harder and more durable metal. Iron production in significant quantities began around 500 BC. Archaeological finds are very rare because the metal was so valuable, artifacts were rarely lost or discarded.|
|The Romans produced large quantities of iron. They had various sources of iron ore with the key source being the island of Elba. Extensive deposits of hematite occur there. Hematite is pure, concentrated iron oxide and is an excellent iron ore.|
The technology required to separate iron from its ores and convert it into useful objects is far more complicated than that needed to work copper and bronze. It requires a temperature of about 3650 degrees Fahrenheit (about 2020 degrees Celsius) to cause iron to melt sufficiently so that it will flow.
