Usually, Wine-glasses are made in three
pieces; those in two pieces, like the following, have the stem drawn
out of the bowl.
The first gathering is as usual,
A; it is then expanded,
swung out, and elongated, as
B; from the thick part,
C, at the bottom of the bowl, the stem is drawn out with
the pucellas while rotating, until it gives the form,
D.
Of course, during the drawing, it has to be rubbed by the pucellas
on the inclined plane of the blower's chair, and rewarmed as often as
necessary; when whetted off at the dotted line,
E, it
is prepared for shearing, as sketched in the former diagram; so soon
as the foot is added and opened, as
F, and sheared, the
bowl is flashed and finished, as
G. This form is often
adopted for hock and claret glasses. When made very slight, the stem is
so attenuated as to be scarcely thicker than a straw.
Between every operation, as before described,
the Glass must be submitted to a fresh heat in the mouth of the pot,
that the parts required to be shaped may be pliable, soft, and easily
impressed by the pucellas. The re-heating is also essential to the
welding of one piece to another—viz., the stem to the bowl, and
the foot to the stem. After the bowl is
