Topic: Vase, milk over light blue with amber trailing on rim, Stourbridge ?

I certainly think our vases were made by the same company; the watery amber and blue... And they're late 19th C IMHO
Have you tried shining your UV light through the glass, rather than on to it. Sometimes the opacifier seems to reduce the effect when UV light is shone onto the surface

Yes, the blue & amber both look the same to me , and if the pontil mark looks the same,  then they must almost certainly  be made by the same company, as you say . In that case I can't understand why mine isn't responding to this UV pen. There isn't any colour change in the purple light anywhere, even when shinning it trough the glass.  I guess the uranium would be in the blue colour and not in the milk glass .

No the uranium is in the milk, but it's not unknown to find U and non-U versions of the same design

though it's generally more common is pressed glass made over a long period

Thanks Christine,

That's interesting ! The uranium doesn't seem to make any difference to the look of the milk glass so there is little point in adding it , it seems !

[Lustrousstone]

Sometimes it does. With the baskets, the uranium one is a richer cream - like the difference between full-fat and skimmed. With pressed glass too it gives richness and depth of colour

Thanks Christine,

That's a good analogy , mine has a definite semi-skimmed look about it    Cheers, Mike.
