I have wondered about the so called crystal leaded glass and if it was much the same as the CRT's. I didn't look at the link above and I have never tried to research the subject as it didn't interest me enough to do so as I have little interest in crystal and I figured that if they were much the same and that there was a market that there must be some BIG reason that there isn't more talk of it. It seems like a "dark alley" of some sort that is best left alone.

As for having leaded tiles and such. I have no problem with it for use as shielding and such as there is a market for it. The down side I see is when the "Governments" decide that it's like "certain sporting items" that can't be owned by the regular Joe anymore and you must turn what you have in or face the firing squad of the blind lady of just us with adjustable scales.
