That is really fascinating. I'm not clear on how toxic the glazes would be--and obviously no jaws fell off--but it doesn't sound like Fiesta Ware and other bright orange glazed dinnerware wouldn't exactly be good for you either. The funny thing is when I first read that "this uranium could be used in the production of an atomic bomb" I thought, wow, you'd have to buy a lot of gravy boats. Then I realized it was the company's stocks that were seized.
I've been taking a pottery class and it fascinates me that one of the glazes we use, which is a nice, deep red color, looks like pea soup in its raw state. I'm pretty sure there's nothing radioactive in it, but I'd still like to take a Geiger counter in with me.
