regulated with the pucellas. The whole is re-warmed and made ready
to receive the handle, which is prepared by the servitor, and consists
of a long piece of soft Glass, A. It is allowed by its
own gravity to fall and to weld on the upper part of the neck of the jug,
B, exactly opposite the lip; great care being taken that
the part receiving the handle is free from dust, or the sulphur which
arises from burnt coal or damp wood, which would render the adhesion
incomplete.
As soon as the handle welds firmly, it
should be separated from the iron,
F, sheared through;
and the workman instantly takes it with the pucellas,
C,
and throwing it a little back, and then forward, he slowly draws it
back again, and gently presses the other end upon the lower part of the
neck of the jug,
D. When this part likewise adheres,
the handle is shaped by rotating the jug and distending the handle
by centrifugal motion, as
E. The handle side is then
turned upward, and the pucellas gives the finished form to the handle.
The jug is, lastly, warmed all over, and placed in the lear for annealing.
The adhering parts of the handle (technically called sticking parts) need
gently pressing to assist the welding; and at each sticking operation,
quick rotation f the jug and re-warming are essential.
