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.
