um.. this is a very simple question but.. how was the element iron discovered? And oh yea.. how was it used?
I would like to mention the Iron was used prehisorically:
I would like to quote :
1 - "[b]Genesis mentions that Tubal-Cain, seven generations from Adam, was "an instructor of every artificer in brass and iron[/b]." "
2 - "[b]A remarkable iron pillar, dating to about A.D. 400, remains standing today in Delhi, India. This solid shaft of wrought iron is about 7 1/4 m high by 40 cm in diameter. Corrosion to the pillar has been minimal although it has been exposed to the weather since its erection [/b]".
So Iron (fe) (ferrate) has been discovered for while. and its used in many industries that require strength.
