How was iron smelted 3 000 years ago Researchers rebuild

Feb 19 2019 · The Iron Age was a turning point in the history of the Land of Israel. Iron tools began to appear around 3 000 years ago gradually supplanting the softer copper and bronze tools. It was also a time of dramatic political change as the Hebrew kingdoms Judah and Israel began to take shape which may or may not have to do with the advent of iron.
