Copper

About

Copper is among the few metals that can be found in nature in a usable metallic form, known as a native metal. This unique characteristic led to its early adoption by humans as far back as 8000 BC. Over time, copper became the first metal to be smelted from sulfide ores around 5000 BC, cast into shapes around 4000 BC, and alloyed with tin to create bronze by 3500 BC. Copper's cultural significance is undeniable, especially in the realm of currency. From the 6th to the 3rd centuries BC, Romans used copper as money, initially valuing the metal itself before the design took precedence. Roman copper mining and smelting were extensive, with major activities in Hispania, Cyprus, and Central Europe, unmatched until the Industrial Revolution.
