Non-ferrous metals were the first metals that people used in metallurgy. Gold, silver and copper were popular in ancient times. It is less sensitive to oxygen than most other metals. Copper was the first metal that was treated. It was quite soft and easy processed by cold forging. Gold, silver and copper replaced some of the functions of other resources, such as wood and stone, thanks to its ability to take on different forms for different purposes. Due to its rarity, these metals are considered luxury items. The application of copper also marked the transition from the Stone Age to the copper age.
