I’m rather curious how the bar didn’t oxidize and maintained the outer markings. That’s rather remarkable, like that other bar that was found which had perfect markings on it too, oddly enough.

Agree

I’ve seen a few lead bars, relatively young, gray and oxidized.

Tin in the alloy will help, though.

I was wondering that too. Especially in Wales. Kind of wet there.

I will guess lead glaze. The Romans lead glazed their pottery.

Maybe the silver content, plus the moisture.
