Recent findings have revealed evidence that predates this account. Indeed, observations have been made on the natural leaching of copper and the formation of “gall springs” during the East Han Dynasty (206 BC–220 AD) in China. The “Gall-Copper Process” was recorded as being used during the Song Dynasty (960–1271AD). Copper was precipitated from solution by dipping iron into the blue vitriol solution — a process identified as early as 150 BC in China.
