lead leaching

Does anyone know if lead will leach out of old, old pottery? I have
read so many magazine articles suggesting the use of a variety of
antique tea cups - and I have some very old ones. Would the
vinegar test and ?? test work on these? Any comments about old
tea cups?

You asked if leaching is more likely to be more prevalent in old pottery and I
think the answer is yes. Depending on the time period it was produced should
tell you something about the technical skill the craftsmen had then, Also
firing was not as controlled in primitive cultures. I would be very cautious.
