Collected Lead (Pb) Metal from gem bearing gravels – Melting just for fun Lead (Pb) Metal collected from gem mine. When we checked our mineral collection room, We found some old lead metal collection from the mineral bag. We separated lead (Pb) metal from other minerals. after, We melted that raw materials through the traditional blowing pipe system. We did it just for fun.
