Hi folks new to the site and new to glass collecting. I have carried out some research and enquiries as to the origin of this glass vase. It appears to be close to Clutha glass but has a ground and polished base. The rim has also been polished and has the characteristical scratch marks around the rim. There is no makers mark which makes me question whether it is Clutha glass. However the colours and bubble inclusions indicate Clutha glass. It stands roughly 7" tall and 7" at its widest point. I have read the article in Scotland's glass 400years of glass making. It is informative but it isn't definitive. Any thoughts would be appreciated
