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.
It is bluish-white, very dense, and has a low melting point. Lead is found in veins and masses in limestone and dolomite. It is also found with deposits of other metals, such as zinc, silver, copper, and gold. Lead is essentially a co-product of zinc mining or a byproduct of copper and/or gold and silver mining. Complex ores are also the source of byproduct metals such as bismuth, antimony, silver, copper, and gold. The most common lead-ore mineral is galena, or lead sulfide (PbS). Another ore mineral in which lead is found combined with sulfur is anglesite or lead sulfate (PbSO 4).
