This is my third attempt at an old piece of glass. This one is 11.5cm in height and 5.5cm diameter foot. It has 6 facets on the bowl as well as the stem. The facets overhang just below the lip. A six sided foot that is quite thick at 5mm. The pontil area is concave and smooth. It doesnt have much wear on the base as it sits on the outer edge. Just a guess until I get more time but could it be Victorian ?? A Jelly Glass ?? A cheap buy at £2 and worth a look into. Thanks all.
