Found this lovely little wine glass today, yep in the same charity shop, and I kinda fell for it. The glass is very thin and delicate, with a number of inclusions, even more when viewed through a loupe, small bubbles and a few little black specks. Twisted stem, very thin foot and engraved design with a small applied panel of ruby glass which has been gilded with a coat of arms. There is a very small pontil scar which is difficult to see but can be felt when running your finger over it. Some signs of wear to the base of the foot and a few scratches on the upper surface of the foot. I'd guess at a European origin, possibly Bohemian but other than that I know nothing about it. Would love to hear your opinions on it.
Measurements are 9.5cm in height, 5.7cm across the foot and 5cm across the top of the bowl.
