At the Vinča culture settlement of Belovode in eastern Serbia, metallurgists developed the world's earliest securely dated evidence of copper smelting. Archaeological excavations revealed slag droplets containing copper metal and typical gangue elements, demonstrating the transformation from ore to metal. The evidence shows that these early metalworkers were selectively choosing manganese-rich black-and-green copper minerals specifically for smelting, while reserving pure green malachite for bead production. This technological innovation marks a pivotal moment in human history, establishing that metallurgy in Europe developed independently from and contemporaneously with metalworking traditions in the Near East.
