      Obviously, those metals that are part of the periodic table are the result of millions of years of chemical reactions under the surface of the earth (as I’m not a chemist I’m not really able to descrbie that more)

      Man made metals like bronze are the result of our constant evolution of sophisticated tool use – we constantly developed stronger alloys for wealth, weaponry and construction. Those that clinged on to outdated stone didn’t last long!

      Pure metals like aluminium, sliver and copper come from the earths crust, I have found a nice website which gives more information on metals:
