Clear flint pressed glass glows green under uv light is it due to uranium help

Lustrousstone:
I want one too, there's always the odd piece that you can't be sure about. The OH is on the look out but they always go too expensive on fleabay and he hasn't found one at a boot sale, yet...

Leni:
Chistine, Uranium in glass won't set a Geiger counter off.  See my reply to the post on Moser  ;)

Glen:
Some of it might. A few years ago (actually over a decade now I think about it) the Head of Physics at my childrens' school helped us to do some experiments using a hand held geiger counter and a variety of vaseline pieces. I will try to locate the results (they are in the depths of my archives somewhere  :-[) but I can recall that the piece that kicked it off the most and got the highest reading was a modern Summit item. The older glass didn't react anything like as much, as Leni says, but it did tick a bit.

I also (ages back) conversed with a very learned man who worked with the Geiger Mueller tube. He reckoned it was far better to use with vaseline glass than the geiger counter. Again, the correspondence is buried in my archives. I haven't had the need to use it for some time.

Glen:
Here's an interesting article for students (written in the sort of scientific language I can just about cope with  :P) that uses a Geiger Mueller tube and experiments with household items including Vaseline Glass and Fiesta ware!

Leni:
 :hiclp: Thanks very much for that, Glen!  I've printed off a copy for husband (and son!) -hope that's OK?  I expect they'll be wanting to get their hands on a Geiger Mueller Tube next!  ::)  ;D
