Can confirm that I have now had a reply from Alum Bay Glass (Isle of Wight - UK) - as below - and I would like to record my sincere thanks to Colin Green for taking the time and trouble to reply, with confirmation that this is one of their pieces. It goes without saying that I'm extremely pleased that it is indeed almost certainly one of his own creations. ""Hi Paul it is our glass and is a small round pot probably made by myself in the early 90s.
I designed the shape and the colour was pure glass onglaze metal oxides and not the safer to work with ground glass we now use.
The colour name is Aegean .

Grateful if the mods. can now move please to British Glass. thanks Paul S.
