Glass Message Board

I hate to be a gainsayer, but ...............   the linked article draws attention to grape and vine engraving, imperfections in the glass, and the evidence of a snapped pontil  -  all of which can be found on glass throughout the C19 and to some extent into the C20 - so such features are far from conclusive for dating.            In the 1920 - 30 period, there was a passion for replicating Georgian styles - all of the big glass makers indulged and they made some nice pieces, that are now the best part of a century old and with use will now show all the signs of antiquity, and be difficult to separate from genuine C18 pieces.     Probably fair to say that it takes time to learn how to assess old glass  -  features such as shape and colour can help, but as NevB says handling something in the flesh really is the only way to feel as sure as we can be, and spending much time at fairs handling old pieces is essential.   
I'll just repeat my comment about the engraving - it looks very crude compared to period work, and looks very white  -  not what we'd expect to see on an old glass.          The Georgians were long lived  -  1714 to1830  -  so perhaps we should try to be a tad more specific.

Thank you for the reference link.
Checking my glass against the described criteria, it seems to tick all the boxes, making me fairly confident that it is Georgian.

Found this stopper which i thought was Mdina but i am not to sure on that it seems a little lighter
in weight than most Mdina stoppers i have owned before?? It measures 2 3/4" long and the ball is
1 3/4" in diameter approximate. Any thoughts would be great thank you for looking.

I like it too, the light was fading on Sunday night when I snapped the photos so it looks slightly duller than it might. Yes I got an Alum Bay vibe as well, along with a hint of Aurene from Isle of Wight Studio. However that might have been influenced by my reading that there was some crossover of personnel between IoWSG and Merlin.

The shape sort of echoes one of the Liskeard Knobblies but I may be reading too much into that as well...

thanks for looking in the book.     I've had a number of pieces of Nazeing over the years although they've now all gone, but from memory none had this clear colour to the glass.        I think the bubbles here are too uniformly stretched  -  again, from memory, Nazeing bubbles are more irregular.        Must be patient - hopefully in time someone may recognize this one.
