kilns, where it is heated 
and then allowed to cool. 
After the annealing the 
glass is dull, so it is then 
ground and polished and 
smoothed. Leather and 
felt are used to give the 
final polish. 
It is made from 3/16" 
to 1 Yi" thick, and the other 
dimensions vary according 
to its uses. 
Plate glass differs from 
other glass because of its 
different production proc¬ 
esses, its freedom from 
waves, blisters, streaks, 
hills and dales, its uniform 
flatness, brilliancy of pol¬ 
ish, clearness, strength, 
luster, and unique beauty. 
Because it excels in these 
qualities it is better for the 
eyes than any other type. 
Here there are no hills to 
be hurdled by the long suf¬ 
fering and jumping eye. 
Therefore, the landscape seen through home 
or motor plate glass is enriched and the car 
and house beautified by the invisible sep¬

P LATE glass has for¬ 
merly been looked 
on with awe! You 
have known of its existence 
in store windows and heard 
of it being smashed by re¬ 
calcitrant autos. You have 
seen it in home windows of 
fine dimensions, you have 
noticed it in limousines, 
yet few realize that it is a 
useful thing inside the 
home. 
Plate glass is made by 
casting and rolling, not by 
blowing. The materials 
for its manufacture are 
chosen with great care. 
The better the glass, the 
better the whole process, of 
course. It must be so made 
as to be almost free from 
color. The great thickness 
of this glass would make 
tint undesirable. The ma¬ 
terials are usually pure 
sand, pure form of car¬ 
bonate of lime and a sulphate of soda, with 
the addition of carbon in the form of coke, 
charcoal, anthracite coal and arsenic. 
These ingredients are all melted in cruci¬ 
bles and when free from bubbles and when 
viscous, the mass is poured on iron casting 
tables and rolled into sheets. While it is flat 
it must be annealed, and it is rolled into the
