Iron was likely originally discovered and extracted as a result of wood burning on top of iron-containing ores. The carbon within the wood would have reacted with the oxygen in the ore, leaving a soft, malleable iron metal. Iron smelting and the use of iron to make tools and weapons began in Mesopotamia (present-day Iraq) between 2700 and 3000 BC.
