- noun glassblowing A
punty; a metal rod used in the glassblowing process. After a glass vessel has been blown to approximate size and the bottom of the piece has been finalized, the rod, which is tipped with a wad of hot glass, is attached to the bottom of the vessel to hold it while the top is finalized. It often leaves an irregular or ring-shaped scar on the base when removed called the "pontil mark".

Following the steps of the young wide-awake, Miselle saw him deliver the pontil, with the lantern still attached, to a listless individual seated upon a bench whose long iron arms projected far in front of him, while an idle pontil lay across them.
To the end of this the assistant now touched his pontil, upon whose end he had taken up a little more glass, and this, being twisted in a ring round the foot of the stem, divided from the pontil by a huge pair of scissors, dexterously shaped with the plyers, and finally smoothed with a battledoor, became the foot of the wine-glass.
