This is a beautiful example of pillar mold glass. Pillar molding combined free-blowing with the use of a mold to give the basic pattern of ribs. The piece, while still hot, could be expanded and finished.
Although also made elsewhere, it is predominantly a product of the Pittsburgh area glass makers during the 1835-1870 period, with heavy production particularly for commercial use.
Clear, clean with a wonderful bell tone.
Pontil scar on bottom, polished pontil on top of cover finial.
Examples shown in Innes' "Pittsburgh Glass".
Size: Approximately 9 3/4" high (with cover), 7 1/4" diameter.
Condition: Excellent. 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, returns are no problem if I happen to miss anything.
