Timeline: History of Metals
Metals have become an important part of our everyday lives. From the common tools we use today to working with advanced machinery, almost everything requires the use of metal in various forms and compositions. Before man discovered this thing in native metallic deposits, the human race live in an ancient time known as the ‘Stone Age.’ The discovery of copper, the first source of metallic material used by humans, started the ‘Metal Age.’ See the history of metal – from gold to iron to rhenium – in this illustrated timeline.
