Topic: Whisky Tumblers - Uranium and Coloured

[Sharose]

Hello everyone,

I would be most grateful if anyone could assist me with an identification for this set of tumblers. I thought at first they might be Whitefriars but the general consensus on the WF board is no. Others I have seen do not have the solid red tumbler like mine does, instead they have a clear flint base. And I have never seen any with the very strong Uranium content on the green glass. Any opinions would be welcomed.

Czech possibly. I bet that purple one changes colour between incandescent and fluorescent lighting  :huh: - neodymium glass

Thanks for the clues. I'll go google some more

These have cropped up quite frequently. I have one of these in blue and one in a smaller size. I have never seen such a selection of colours before.

Opinion at Whitefriars.com generally refutes that they are Whitefriars and I think that's correct although they are not bad quality and the texturing is very similar apart from near the rim. Possibly the weight is also different.

Ravenhead has been suggested but I think they generally concentrated on clear glass and the patterning is slightly different to my Ravenhead Siesta tumblers.

They definitely bear no resemblance to the nasty Royal Castle vases and the texturing is quite different to Johansfors and definately superior to the Oberglass vases.

Googling won't help at this point. Once we know for sure if the purple (lavender) one changes to pink under flourescent light and is therefore neodymium glass. If so then that narrows the field down significantly.

There have been some seen with an Italian (generic) label on them by one of the whitefriars.com members.  They are quite a good quality,  Emmi

Hi people!

David,
Thanks for that link. It's very interesting. My purple glass turns blue under the fluoro light. I thought it was supposed to turn pink, or is that something else entirely? It's really a marked difference. I've been nipping from the study (fluoro) to the bathroom (incandescent) and then turning the bathroom light out and putting my blacklight on (nothing apart from the green one).
The family think I'm nuts...

You've got me checking them all now  :huh: .

They're pressed glass with straw marks, 85 mm tall and weighing between 185 and 225 g. They're all a different weight, the purple (or blue ) one being the heaviest.

 The green one is really very startling, and the red one shades from a very deep red to an orange near the top under the fluoro.

Thanks, Pete, as well. Emmi, the ones with the Italian sticker (I think) had a clear glass base to the red glass, so slightly different again. I'm confused (nothing new in that)

DOH!

Please excuse me. I just re-read that article and of course it's meant to turn blue. (Not pink) How exciting. I have a piece of glass I never knew anything about. now all I have to do is learn to spell neodymium

This makes me suspect this set must be fairly good quality, even if the maker is still something of a mystery.

Lilac to pink is neodymium, which is spelt "neodymium"

A good bet for it being Czech then - I'll give Marcus (www.sklounion.com) a nudge.

Can I have a star for guessing it might be neodymium? Once you've seen it, its a very distinctive lilac
