Hello all, i'm struggling with these and would appreciate any help. There made from thick cobalt glass with some age wear to the base and a snapped pontil, lots of bubbles and seeds in the glass. My first thoughts were Italian due to the shape, but they feel too thick and heavy and the pontil is large not like the Italian glass i own. Then i thought maybe something modern by the Bristol blue company but there bits are normally crystal clear or at least the glass from them i have come across have been, i have drawn a blank.
There 5 1/2 inches in height, 2 3/4 inches across the base and 2 1/2 inches across the rim.
regards Chris.
