morning Otis. In view of the height of the stem I'd suggest a goblet rather than a wine.
attached is a pic showing a very similar pair of tulip goblets which have the single word 'Webb' backstamp - these bowls also glow - and the suface effect pattern appears to be something called 'Moire', introduced about 1907, although the glasses are much later, I'm sure.
Unfortunately, as we know only too well there is much T/Webb material out there which is unmarked.
The underside of the foot on mine are simply flat with just the hint of a raised area in the centre - definitely not a ground/polished pontil depression.
Regret I can't see the surface pattern on your bowls clearly enough to match with the book - it might be possibly be honeycomb, pineapple or lattice even.
I'd have thought that these things might date to around 1930 or thereabouts, but am really not sure. Backstamps can be a bit misleading and as people have commented previously, date lines for beginning and end are a bit blurred.
I don't know whether Webb used uranium after 1945 or not.
I'd say definitely not Stuart - I've yet to see a piece from that factory with uranium.
Anyway, it's possible that your piece might be T/Webb, but nothing more definite than that I'm afraid.
