Iron Age

Subsequent to the use of bronze and copper,man learned how to make use of iron.It was probably in 4000 B.C that the first objeats made with iron appeared in the middle east.The first people learnt how to hammer iron into various shape.It was much later that they discovered that iron could be heated and hammered into various shapes much easily.It was around 1500 B.C that people learnt how to extract iron with heat iron core and then hammer it into various shapes.The celts of Europe were the first to use this technique.Some of the earlier implements and tools made in this manner were razor,knives,tongs,blades etc.The technique used by celts slowly became popular and around 1000B.C spread to the other parts of Europe.Around 400B.C this technique of making things out of iron spread to the other parts of the world including China.The chinese contributed to the devlopment by making powerful bellows which allowed the temperatuer to be raised much higher thus,producing iron of a better quality.Subsequently the advent of the industrial revoulution further advanced the use of iron and the devlopment continues even today.
