Only Earth Things on Instagram: "Ancient metallurgists refined gold through cupellation, a brilliant technique where impure metal was heated in a special porous clay cup that absorbed lead and other impurities. As the fire roared and oxygen flowed across the molten mix, unwanted metals vanished into the cupel, leaving behind a bright, pure bead of gold — a moment that felt like turning fire into treasure. #AncientMetallurgy #Cupellation #GoldRefining #HistoryFacts #DidYouKnow #AncientTechnology
