this Walther & Sohne vase appears to be uranium? ive not seen much blue uranium glass tho.. what do you think?
-
There is blue Uranium glass "out there", but this isn't it. What you have is a green, smudgy, but faint "green glow" from manganese which has been used as a decolourant in the batch of glass melted.

ah ok.. I thought manganese was used mostly in clear glass??
but I stand corrected :)
many thanks

It is, :) to get rid of other colours that might appear, (eg a yellowy colour from too much iron) but it reacts a bit to UV light.
Cadmium and selenium react to UV too.
I learned pretty much all I know about glass here, it's what we're here for, to learn and to pass knowledge on. ;D
If you want a look at a wide range of uranium glass (and lots of it), click on the link to Lustrousstone's Gallery, there's a link in her signature, all her glass is photographed and beautifully organised into albums.
