Prehistoric metallurgy refers to the early techniques used by humans to extract and manipulate metals before written records. This period began around 6000 BCE, with the discovery of copper, which was one of the first metals to be used. Early humans learned to smelt ores, allowing them to create tools and ornaments, marking a significant advancement in technology. As societies evolved, the use of metals expanded to include bronze and gold. The Bronze Age, starting around 3300 BCE, saw the development of alloying techniques, where copper was mixed with tin to create bronze, leading to stronger tools and weapons. This innovation played a crucial role in the advancement of civilizations.
