Hi, I was the person who started the threat on pewter.
I hope that you know what Pewter is, it is a silvery, soft material
that is used to cast little statues of dragons, gnomes, fairies and
all kinds of fantasy items. I recently found a company that sells
sheets of pewter, they have many sizes in thickness, the sheets are
12" x 12", My metric ruler is not by my desk right now. Pewter used to
have lead in it, it now does not have lead content. It is very easy to
bend and is very soft.
I hope this helps, possibly someone else there knows the formula of
what it is made up of.
Sorry for not explaining better what it was.
