The kind of cut glass that Is coun
terfeited is called open work. such as
plates. naples or any fat article
through which the work man can read
lily see when finishing it.
Another help In selecting cut glass
is it's weight. The genuine IS made
from pure lead glass. made chiefly To
America. especially for cutting. This
lead glass is very heavy.
The first step toward cutting is to
mark on the "blank"-that Is. the dish
in the clear glass-in red or other paint
the design that has been selected for
it.
The most common designs are .dia.
mond shapes. stars OF various points,
crosses and squares and other geomet.
rical patterns.
The design must be marked on the
glass exactly to stand the test of com.
pass and rule. When all lines are In
perfect accordance with the pattern
and also fit the blank the ''roughing"
begins. This is cutting the heavy work.
such as the necks of vases and bottles
and the heavy lines on the stars.
This is done on machine called the
''mill." big wooden framed affair. on
top of which is a hopper holding about
half ton of Berkshire bills. sand
This sand is the only kind In this
country that has proved satisfactory
for this work.
The sand runs down through the
hopper, is moistened with water and
comes out of a large steel disk. the
edge of which is sharp. This disk is
turned by power at a very high speed.
The wet sand Of the disk gives it a
''tooth." which when the glass Is held
against the edge of the disk cuts very
rapidly. .
All the coarse and heavy cutting is
done on this mill"

but much narrower and with beveled
edge. These stones come chiefly from
Italy or Scotland. They are very hard
and carry keen edge q long time.
They are used for the tine cutting al.
together.
There is a stone found in Nova SEQ,
tia much softer that cuts quicker and
is used for fiuting GU water bottles
