I think you should just put your money where your mouth is and test some
pieces to be certain that fuming has not contaminated the kiln and allowed
some cadmium--and yes, some lead from the stain--to deposit in the insides of
the pots. Then armed with this data, you would have some ethical basis for
your "no tell" policy.

And the public is getting more sophisticated. One day they will ask. It
might be nice to be ahead of them. Good potters with good products have good
answers to any question about safety they may be asked.

I admire potters like Ray who not only sell, they educate.
