Can anyone enlighten me on this glass? Bought in Holland and described as a dram glass it is 11.5 cm tall,. The bowl has the usiual tool marks and striations associated with hand blown glass. The metal, which has aslight greenish tinge, comtains small bubbles and inclusions some of which are quite brown and also gives yellow luminescence under UV. It possessses a domed, folded foot with considerable wear and a rough pontil mark.
Where do you think it was made and when?
