Molten lead color. Hi all-I was doing some casting this weekend and noticed that I couldn't quite keep the color of the molten lead a shiney silver color (like quicksilver / mercury).Instead, it was more of a gold color, with a thin skin on the top.old is a good indicator of tin. pure lead will usually show a blue/purple color. put a heat barrier on top of your mix it will also help keep the oxides down and the temp more consistant. it's all an educated guess,,,, till the trigger is pulled.
Lead: the essentials. Lead is a bluish-white lustrous metal. It is very soft, highly malleable, ductile, and a relatively poor conductor of electricity. It is very resistant to corrosion but tarnishes upon exposure to air. Lead pipes bearing the insignia of Roman emperors, used as drains from the baths, are still in service. Alloys include pewter and solder. Tetraethyl lead (PbEt 4) is still used in some grades of petrol (gasoline) but is being phased out on environmental grounds.
