Origin of pontilFr: see punty
Origin of pontilFrench, possibly from Italian puntello, diminutive of punto, point, from Latin p&umacron;nctum, from neuter past participle of pungere, to prick; see peuk- in Indo-European roots.
- (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".
