lowered into waiting metal mould
which Is then closed with the eXcep-
tion Of a small aperture at the top.
Through this aperture the blow pipe
or rod Is stih IN contact with the
moulded mass. The operator then
forces quantity Of air through the
pipe into the center of the fluid The
glowing substance Is then forced 10
the sides of the mould until from eX-
cosslyo pressure the air conduit breaks
off at the aperture. The mould is
then opened after some thirty seconds

object is reheated and pressed for al

The furnace Of the Sand Springs
company Is fifty feet long twenty feet
With fire brick and cut stone held to.
gcther by steel scaffold Gas burn
crs are placed in the sides and ends at
Intervals Of few feet, dlscharging
constant sheet Of flame. At one end
Of the furnace Is a low aperture,
through which necessary materials are
passed into the glowing interior; here
they become a part Of the liquid fire,
fiery enough TO materialize any school
boys conception of the underworld
An opening in the furnace, for tho
drawing off OF the liquid Is provided
for each pair Of glass blowers These
two blowers work in conjunction with
third who operates a mould. These
three men interchange positions at
short intervals TO relieve the strain.
Each blower possesses a helper, MAX
ing a party Of six men working to-
gether. Large air blowers play con-
stantly upon the men subjected to the
heat, and vessels Of water are placed
in places of easy access as the work
ers must dip their hands continually
in water, owing to the intense heat
OF their tools
The tempering oven is of brick and
is several hundred feet In length, the
bottles are plf ed IN one end upon
slowly moving tramway moving 50
slowly that it requires several hours
for an object to pass from one end
to the other. The furnace Is divided
into several compartments, each one
of which possesses a lower tempera-
ture than its predecessor. BY the time
an object has traversed the entire dis
tance it has been subjected to a heat
varying from several hundred degrees
Fahrenheit to summer heat.
The discharglng end is PLACED in a
separate building. Here the product
is Grated and packed as the conditions
may necessitate. The bottles are us
ually packed in cases containing one
gross, the cases are then sent on to
the shipping room where they are
stenciled and loaded upon the cars
of the Sand Springs Interurban rail-
way, a spur of which enters the yard
of the glass factory.
Connected with the shipping room
are two buildings, In one of which
the cases are manufactured and the
other in which quantities of. supplies
are stored and rows and rows of the
Grated finished product. reaching to
the roof
The fifth building serves as an en-
gine room and the store room for the
raw material. The motis, power here
as in the other engine rooms of the
new city is the famed oklahoma nat
ural gas. Everywhere over the fac
tory sites can be heard the hiss of the
pressure regulator. The power is
used in the glass plant to propel
huge blower which sends continuous
current OF air through the building
in which the glass is made. 1t also
propels a mixing machine greatly re-
sembling the concrete mixers used In
pavement construction. Into this the
materials going together to form the
glass are mixed in right proportions
