THE COLLAR IN THE BALUSTER STEM
“WILLIAMITE” GLASS: NOTE THE “COLLAR” ON THE BALUSTER STEM
Often the stem does not directly join the bottom of the bowl, but has a “neck,” with an outstanding ring of glass or “collar” around the neck; sometimes the collar is double or triple; the neck and collar were often used later, in other than baluster stems. Sometimes the collar is near the foot; sometimes there are two collars. Around some stems a fillet is found; these are very rare.
