Hello all on this fine sunny day.
I wondered if anyone could kindly confirm if this is Pate de Verre. Ivo previously mentioned that the French are notorious for calling a lot of their glass PDV wwhen in fact its not. I have a little doubt because the applied yellow decoration is shinier in some parts than others. Quite a weighty item. If anyone does know its manufacturer that would also be very much appreciated.
Many thanks
Margi

highly unlikely Marg - looks Chinese to me - sorry to say. I assume it doesn't glow. Why should the French want to call glass pdv, when in fact it is not....is this a commercial sales ploy aimed at the unsuspecting tourist. ;D. The texture and colour look far too uniform to be pdv.

There would be no point in making something so simple via the complex and costly pate de verre technique. http://www.warmglass.com/pate_de_verre.htm

Thanks peeps. The green doesn't glow but the yellow glows a more brighter yellow. Incidentally talking about UVs what wavelength am I supposed to be on?
-
according to Barrie Skelcher who was a health phycist at Sizewell - Uranium fluoresces most strongly with uv in the 'near range' of wavelengths i.e. around the 380 - 400 nm, and less well in the 'far range' which is at about 150 nm. most of the torches that we use are something like 385 - 395 nm. If you go to buy one, take a piece of U. glass with you - that way you can't go wrong. ;D

Got a different light today and was testing various pieces. I popped this against it and wow the yellow glowed so bright was quite surprised. Does anyone kindly have a feel of who could be behind the making of this piece please
-
hello Margi - are you saying that the yellow is actually fluorescing, or simply that being shiny it is reflecting more light than previously because your new torch is that much more powerfull. Do know the wavelength of your new torch, and where did you get it from, if you don't mind me asking. Perhaps you have supa-dupa batteries ;D Don't think the yellow is U. glass, as it would need to be green to qualify for that category. Sorry, still can't help with a manufacturer, other than saying it is possibly Chinese.

I have no idea what wavelength I have now except it runs off the mains and that it has both white and UV lights. OH bought it but sorry him being a man (well sometimes not sure) he has forgotten where he got it. Will take pic later tonight to show the diff in the yellow it definately glows i was quite surprised myself. Not doubting the origin just sharing my findings :kissy:
-
Good evening here is the vase under UV not photoed as well as I hoped but still shows. Also is it normal for the green to then look blue.
-
Cadmium sulphate in the yellow I think
-
UV light will make Uranium glass glow GREEN, not a brighter yellow.

Yes I appreciate that Sue, was just trying to fathom out what compounds would make the yellow glow. I have been reading about the one suggested.
