Interestingly, I had the same thing happen to balls that were left for some time in my Pietta 1851 case that looks like this one. However, so far as I can see anywhere in chemistry literature, there is NO oxide of lead that is white. PbO is red or yellow (2 forms), PB3O4 is red, PbO2 is referred to as either brown or red/yellow, Pb203 is reddish yellow, Pb12O19 is dark brown or black. If people want to continue to refer to a white lead oxide, I'd just like them to tell me what the formula is for that and provide documentation for it. Can someone please provide the formula for these things that they are calling white lead oxides?Lead oxide forms on lead exposed to the atmosphere. I have some 36s cast up in the early 80's that never touched the ground that are all white and flakey with lead oxide. They look great in a cased display, just don't touch them.
Apparently lead carbonate is typically made from lead acetate and carbon dioxide. So I wonder if the balls in the gun cases may have formed it from being in contact with acetate lining cloth. Just speculation. But I really would like someone to point me to a clear account and chemical structure for the white lead oxide they keep referring to. Just as a matter of accuracy?
