Bubby, Thanks so much for all your hard work and research. That was a very good report and very interesting information!
Jim, should you come back on here, you might want to read this thread that deals with lead in today's glass.

You could also check out the Bullseye website and I think the CR Loo website also lists the lead-free glass it has from the different manufacturers.
Some of you who are interested may want to look into the melting of glass and the refining of that glass during the melt, which removes the bubbles, a step that is necessary in creating a good quality glass.
