Title: Can Anyone I D this Uranium Glass Bowl Please?
Post by: theElench on March 03, 2021, 03:55:04 PM

I'm not usually a great fan of this sort of engraved glass but I think these stylised fronds are quite attractive.  I'm guessing it's 1930s, European? 

If it's any help, the cutting seems very finely done with each leaf and rectangle filled with very fine lines, giving them an almost textured appearance.  It glows very strongly, has numerous air bubbles and a couple of very small black inclusions.

Thanks for any ideas.

I can't find one exactly the same but did find this with similar decoration.

Also if you look in the 1936 Schwepnitz catalogue in the German on www.glas-musterbuch.de there are some Rienzi bowls with the same three ball feet, I can't find a way to link them.

Thanks Nev, there's certainly enough similarities to make it worth looking into.  One way of measuring the diameter even come out at 224mm.  Will have a look for further images.

Have added a couple more photos of the bowl under UV. :)

Nice glow  :)

It is indeed and although my photos don't show the effect at all well, the very thin lines within the leaves give a slight 3D effect visible to the eye, due to the different thicknesses of the glass.

I've never been sure whether the designers / craftsmen knew how artistic the effects they were creating would be or whether it was just luck.  This bowl seems to say that they did.  The leaves look flat in daylight, but under UV appear textured and more lifelike.

The same is true of the vases I have on my lounge window-ledge (four floors up and facing West).  Sometimes the Uranium Glass ones produce almost a mini-lightshow at sunset, on a clear day.  The glow rising and falling slowly through the various facets and thicknesses as the sun goes down.

I think my window glass has a quite high UV protection factor so I don't get much of a lightshow  :( . I have to take pieces outside to really get the full effect.

I think being up on the 4th floor also helps.   As the sun gets near to the horizon it hits the vases almost horizontally.

Try an upstairs window?
