Here is an exerpt: The products of the Margariteri and of the
Paternostri guilds differ in several important
respects, the first being the gross size of the
beads. The Margariteri produced chiefly seed
beads, and while there is some overlap in sizes,
the Paternostri generally made larger beads. The
chief difference between the two guilds was
how the beads were finished. The Margariteri
finished their beads “a ferrazza” (on an iron pan)
by stirring them over heat, while the Paternostri
finished beads “a speo” (by the spit) (Gasparetto,
1958: 186). Francis was the first to report this in
English (Sprague, 1985: 91; Francis, 1979c: 8),
but it was left to Karklins (1993) to uncover
the details.
In the a speo method, segments cut from the
drawn tube are mounted on a unique tool. This
device has a round metal base held by a wooden
handle. Six or so tines arranged evenly around
the edge of the base rise perpendicularly from the
base in the direction opposite the handle. Several
glass tube segments are placed on each tine. The
metal part of the tool and the segments are held
in the fire and rotated by hand. The segments
began to soften and assume a round bead shape.
