THE RAISED FOOT
Because of the pontil-mark being often a knob, or protuberance, the foot of the glass must not wholly rest upon the table, but touch it near the circumference of the foot only, lest the knob at the end of the stem should prevent the glass standing level, or should scratch the mahogany.
THE DOMED FOOT
Some of the oldest glasses, in which the pontil-mark is quite a large protuberance, stand upon feet which, flat upon the table at and near the edge, rise domelike in the centre. These dome feet are seldom symmetrical; made by hand, the flat part is usually wider on one side of the dome than on the other.
DOME-FOOT
HIGH INSTEP FOOT (TWO VARIETIES)
THE HIGH INSTEP FOOT
As the pontil-mark became smaller and not so rough, the dome foot gave place to one which is mainly flat at the base but slightly conical, rising like a low round hillock, to join the stem: seen in profile, these somewhat resemble a leg and a foot with a high instep. No seventeenth-or eighteenth-century stemmed drinking glass except a “firing” glass has a foot with an uniformly flat section.
