Antique teapot glass handle


Recommended Posts

I've had this antique teapot for a while, and wondered about the yellow-green glass handle. After setting it up with the Convoy, it would appear the the handle could be Uranium glass. The J. H. Hopkins & Sons stamp on the bottom places a 1850-ish manufacture date on the teapot, but I'm not sure if they even made Uranium glass back then.

oh wow! That really does fluoresce. Quite amazing. It almost looks like it is "red hot" except for being green. :lol: :lol: :lol:

This is a really nice find.

 

Long time past we had some posts about glass here. Try a search.

 

 

Wikip: The use of uranium glass dates back to at least 79 AD.

That looks really cool. I didn't know of Uranium glass. I wouldn't worry about it. It would be 238U and would need enrichment to do much or conversion to plutonium to really be dangerous.

Also from what I just read, they mostly used up to 2% by weight. But you can sometimes find upto 25%. However, since yours is not glowing by the window from natural uv light leaking in, unless you have new tripple pane windows, I think you have a small amount of 238U there.

 

That said I would worry more about that old metal. Various anaerobic bacteria may be hidden in any dirty, long unclean areas. That I think would be the biggest risk.
