large uranium green vase
« on: November 26, 2012, 12:32:39 PM »
Hi,   I've been trying to identify this uranium green vase, very deco in shape, thick and heavy. Its 8 inches tall (20cms). 5 inches (13cms) across top. Quite a simple shape, I like it a lot. It will look lovely full of daffodils in the Spring. The base is completely flat with a lot of wear marks. Been looking hard but I can't find a similar one. Does anyone have any ideas please. Thanks as always  , Cheryl

The question is though is it "uranium green" (which is a misnomer as uranium is a yellow colorant) or green uranium glass. The latter is the only accurate descriptor and only if the vase glows a very bright green under a UV light.

Hi, I put the vase under my UV bulb and it does glow, sometimes hard to tell if its just reflecting the light, some glass I have glows an awful lot while others are not so bright like this one.  Did this vase come in uranium green or is my "glow" just the light reflecting through the glass?

That will depend on the shade of green - UV light is purple (hence the name - violet) and if this purple light turns really bright day-glo green, then it's uranium. If it's only a faint green glow, it will be manganese.

If it does not glow a lot, it does not contain uranium. Sounds like it contains manganese (this gives a dull greenish yellow glow), which was commonly used as a decoloriser even in coloured glass. The pre-war versions probably contained uranium; the post-war ones won't
