[Sca-cooks] Tin/Pewter Was: Cornish Pasties

[Lisa]

Not sure on the tin, but you are very correct on pewter having Lead rather
than tin in it.  Most pewter made today is made from lead free pewter, and
is therefore safe, but if you don't know the age of the piece, I'd avoid
using pewter for eating or drinking utensils.  My husband recently made some
site tokens out of pewter, and he made absolutely sure that they were made
from lead free pewter on the slight off chance that a child might get his or
her hands on one and put it in their mouth.
