Very old antique one pint size aqua blue glass mason jar with a zinc metal lid. This jar is embossed with "Mason's Patent - Nov 30th - 1858". The jar is also marked with an intertwined "C G Co" logo. We were told that this is for Clyde Glassworks Co.
This is an original period jar and not a newer reproduction. It in nice vintage condition with wrinkles and bubbles to the glass.
