Topic: Red vase that base fluoresces golden yellow i.d?

[I love all Glass]

Hello to all, I bought this red vase because it looks great, has a gold coloured clear base with polished pontil, quality and heavy. So tried my UV on it and lower half of vase fluoresces golden yellow, from outside mainly, so encased I guess. I took picture next to a regular UV piece for perspective. Measures 14.5cm rim by 14cm tall and just over 1kg. I thought maybe old English, no marks to base I can see, thanks for any ideas    Simon

Sounds like a cadmium sulphide glow that can often happen with red glass. If you search for "cadmium glow" on the GMB "search" you'll find various previous posts where I have explained this.

Yes Cadmium, the vase looks like a Dartington Top Hat vase, probably FT74 as the sizes could vary apparently. What is the diameter at the base Simon?

Cadmium was used to produce Dartington's flame red, turning the glass from yellow to red with the application of heat (called heat struck). I assume the bases stay yellow as they don't get as hot as the rest (just the mechanics of heating the vase while it is still stuck on the end of the pontil rod).

Example of a Dartington vase that was never heat struck: http://www.glassmessages.com/index.php/topic,22159.0.html

Hello John, thank you for great info, diameter of base is 11cm, but not flatterned top rim nearly as much as one in link for Dartington, did they differ in shape that much? Cheers   Simon

They were made in two 'sizes' with the diameter at the base either 10 or 11cm. That would make yours a large but heights and also the diameter at the top varied as they were hand formed.
