Clear and also uranium tinged butterfly pattern bowl
« on: January 28, 2013, 07:02:39 PM »
Top diameter between 25 and 29 cms
Stands 7cms high.

This bowl is heavy and sits on an elephant foot type base.
The colour is tinged yellow/green

When the dish is turned over to expose the foot atop...you can feel the pattern raised outwards - which I thought was the outside of the bowl.

Im now thinking is is meant to sit as some centre piece with the flower /elephant type base on top with the central hole used for placing anothe piece of glass on.

Its very heavy.

Any ideas?

Thanks
Nicky

thanks for looking lusstrousstone..

I thought because it was yellow tinged green which you can see without any light that meant it had uranium in it and thus was defined as such?

If I get hold of a black light flourecent then would that define it exactly if it shines green?

Regards
Nicky

the slightly yellow/green tint - which I think can be seen (just) in the second pic - might possibly be the result of manganese being used as a decolouriser.            Sometimes a lack of lead oxide can also give a yellowish look  -  glass with a high lead content tends to appear blueish.
Using a uv torch on clear glass containing manganese will accentuate the colour of the manganese and give a dull greyish green colour, more noticable in the thicker parts of the the glass  -  but won't produce the bright fluorecent green of uranium.              UV torches are quite cheap Nicky (on line) and are a very good investment and help if you do occasionally collect uranium glass. :)

Here is one source for suitable torches ......................     http://www.netpcdirect.co.uk/uv-torches-lighting.html  -  for use on uranium glass it's better to go for the higher wavelength figure of 395nm.

I have found a celery vase on Ruby lane that is very close to this dish.

I wonder what makes them think it's British given they don't offer any evidence for that opinion? 

I'd suggest it's pressed glass and I can't imagine why a master craftsman might be needed to facet it - that's the job of the mould it was pressed in...  and what on earth are "blushes" on the edge? I'm looking for pink bits.... :)

Glad you said that Anne as Ive seen a few descriptions that seem a bit flowery and ambiguous.

I have my better camera back in operation and will try to get some more pics that are far better than the last ones  - if thats allowed?

Regards
Nicky
