Cheers , odd one- dont know anything about glass but its very heavily cast- the base it about 1" thicj in places but varies , cant see it being from the recent past- its quite imperfect and 'wavy'.
Anyway it cracked badly while just stting on the coffee table here tonight- just went bang all...
Hello folks,
found this old jar and cleaned it up, it approx 12" in diameter- any ides on age or function. its got no markings except a vague 'o' or 'Q' underneat.
Its got a very thick base and bubbles in the glass.Thanks Alan
