Seems I read somewhere on this forum that tin remains shiny and does not lose its luster like pure lead, does.
And, I have noticed in my stockpile of ingots (which have been stored for about a year or so now) that the ingots from stick on ww's have retained their luster. The ingots that I know are pure lead, are dull.
Does this infer that stick on ww's have a fairly high tin content?
