This clear blown bar bottle or decanter has applied, tooled ribs and applied "blob" top where a cork and pewter pourer would have been inserted (these types of bottles did not have glass stoppers).
You can see the swirls and bubbles where the rings and top were applied and then met. Heavy, clear glass with polished pontil. Early-mid nineteenth century.
These glass workers were certainly skilled, especially when for such a prosaic object. It is possible that the ribs were applied on these items in order to ease handling when wet.
Size: Approximately 9.125" high, 4" bottom diameter.
Condition: Excellent, with only slight interior residue on bottom. No chips, cracks or repairs.
Note that I try to be conservative about condition descriptions, carefully noting any flaws. Of course, with antique items, there will be some signs of usage, and/or manufacturing defects. But overall, my customers have always been pleasantly surprised upon receiving their items, and of course, I would expect a return if I happen to miss anything.
