Topic: Uranium Green Vase

[NevB]

 I've checked the Whitefriars catalogues but this vase is not there. Another possibility is a hopeful attribution to Keith Murray for Stevens and
Williams, the colour is similar to other of his pieces. It's 9.5" tall, weighs 3lbs, has a large 2.75" polished pontil and lots of wear on the base.

is this a uranium glow, or possibly a very strong manganese effect do you think?       Apart from possibly some late C19 material, I had an idea that W/Fs (like Stuart), didn't do uranium in the C20, but stand to be corrected of course.            Sorry this is completely unhelpful as to attribution  -  absolutely no idea as to maker.

It's definitely uranium glass Paul, it glows really well and also gives a strong reading on a Geiger counter. I've found if there is an additional colourant to the uranium, in this case the dark green, it tends to make the glow opaque. Having checked the two types of UV torch, the 395 nano meter one, used to detect uranium glass produces just the faintest glow in glass which contains manganese. Using a 365nm torch produces a much brighter glow, particularly in old clear glass. I'm pretty sure my vase isn't Whitefriars.

Lovely vase Nev. check out my post https://www.glassmessages.com/index.php/topic,72147.msg401592.html#msg401592.
My nephew sent me this picture from a museum on Murano a while back.
I would love to believe my vase was Italian but who knows?

Sorry i forgot to load the picture.

very devious these glass makers    -  the daylight colour of this vase is unusual for a uranium piece, but then again I recall Christine has some pieces that don't appear as uranium green, but do contain this active element and glow well.         Assume this is an optically moulded vase.

Thanks Tim, yes it's quite an impressive piece of glass. I suppose, like yours, it could be Italian, but I think more likely English. Yes Paul it's a sort of vertical fluted optic pattern, difficult to describe.

As was discussed with Tim's vase I believe my vase is more likely to be Stevens & Williams but unlikely to be a Keith Murray design. There aren't many of this type of vase with the vertical ribs online but there are a few in the Rainbow pattern which are definitely S&W. They also have the base with the same sort of bumps formed from the making of the ribs and the large polished pontil. Of course this may be just a coincidence but I think it's a good pointer. Mine also has the prominent internal ribs.
