Hi there
picked this beautiful vase up today, not normally my thing but its gorgeous!!! and it was just £2 but does have a little damage, nothing to serious fortunitly and doesnt effect the display value.
It is a creamy white colour with a green hue, the vase is cased in uranium (im sure i have it right this time christine ;D it glows like made). It has a purple painted effect on the front with little bobbly bits.
I dont know a great deal about this sort of glass but i would guess its early ish victorian around 1880 - 1900 maybe bohemian
can anybody give more any more info or agree/disagree??
It is 24cms tall, 11cms wide, the body is a 4 lobed shape, the base has a snapped off not polished pontil mark (bit sharp)
many thanks in advance

Looks very much like 'Stourbridge ' glass,Webbs maybe?
-
Is it actually cased? Looks like a uranium "milk" glass to me (comes in shades ranging from grey through cream, to yellow and green). Could be Stourbridge, could be Bohemian. I would probably go with the latter. The date could be another 20 years into the 20C. Many of these styles were made over a long period
It also looks like it could belong to the same family as some of the vases linked from here http://www.glassmessages.com/index.php/topic,27574.0.html
Another unknown but yes uranium ;D
-
I was thinking the same thing, Christine - looks like the same style of decoration as is on the shaded ones.
I think it's uranium cased in a layer of clear (or almost colorless, anyway). You can tell by the bubbles near the bottom, and a hint of rough clear on the pontil.

Hi there
ive had a really good look at this and it has a milky white glass internally with just a single case of very pale transparent green glass (the uranuim), there doesnt appear to be another case in clear, ive shone a normal lights through, the UV light, daylight and fluorescent light through but cant see a clear case. The glass has a soft satin effect. The applied handles are made from clear glass which is also satin feel and there is a marked difference between the handle and the body. Its really hard to capture on camera the effect.
many thanks for you help

I think it is more likely that this isn't cased at all, just uranium glass throughout
-
There is definatly 2 parts, the white then the layer of clear green, when held up to the light its really obvious, also when you look at the rim you can see the layer on top of the white rather the a gradual fade to the green. also the white is not transparent which makes it easier to see the 2 different types
I hope that makes sense ;D
thanks

It has all been acid treated (before painting) to give the satin effect. You often find tiny areas where the acid "paint" was missed if it was done by hand rather than by dipping. You can find satin finishes on any sort of glass
If it has an outer green uranium case, it won't have a clear one as well.
-
The light green was what I was talking about. I thought it was colorless from looking at the bubbles, but then after I'd written realized the outer layer was a pale green and added the "(or almost colorless)". Should have just said green! Anyway...Michelle, how do you determine which layer is glowing? Because the outer layer is apparently so pale and thin, I would guess it's the inner one (uranium was used to make opaque white glass as well as greens, etc.). That would conform with the other similar pieces. Maybe it's both layers.
-
I suspect it will be only the outer layer. I have rose bowl with satinated green cased over white and the inner layer doesn't glow; it only reflects the blue. The effect is really pretty on the edge as you get bright green cased over bright blue/purple. The green layer on mine is much thicker at the bottom but that's probably just the way it was made.
-
I will get the ligt on it when i gets a bit darker, that way its easier to see where the glow comes from, The layer is quite thin although is thicker at the low waist (more like ankle ;D)
thanks michelle

You should be able to tell by pointing a key fob light inside or even a tube light across the top. With my tube light the inner layer stays white both inside and at the edge. You have to shine it on the inside because if you shine it from the outside the green light produced is transmitted through the white layer. Green light is not produced until the UV light gets to the uranium layer, so if there isn't any uranium in the white you won't see the green on the inside, just on the outside where it has penetrated the white layer. Think of it like a chemical reaction - it's not a light transmission or reflection effect, so it won't happen until the light and the uranium atoms meet.
-
You're probably right that the uranium's in the outside. At the top, where you can see the inside layer, it looks less bright in the UV photo.
I would think that the effect would be similar to reflection, since the uranium is absorbing the energy then re-emitting it. It's sending it in all directions, not just in the direction it was going to begin with. The difference would be that less light is getting to it from inside, since it has to go through the (semi) opaque white.
