Hi all,this glass is 13cm tall,why is 13 the magic number?,with a lovely long ring and polished pontil,it has wear to three places on the foot it sits on and some to the rim, i guess hinting it was kept on it's rim at times,the stem is green and the foot a lighter amber with the green showing through on the polished pontil,there are a few air bubbles and i think a couple of lighter coloured seeds in the foot plus a couple of small black bits,any thoughts on this glass,many thanks.
