THE 
REVELATION KILNS 
Especially Well Adapted for 
Glass Firing 
Now is the time to order a new kiln for your summer work. 
Discard the old one, which has given inferior service and which 
has been a burden to operate. By installing a Revelation, you 
will be assured of perfect results, economy and general satisfac- 
tion. 
This is onr New No. 3 
which has largely taken the place of the No. 4. It has 
removable tubes in the door, which insure a perfectly 
even heat all around the oven. They may be used or 
not, at the will of the firer, but are an especially desir- 
able feature. 
This is oar No. 4 Kiln 
This was the first kiln we manufactured, and represents 
the infancy of our experiments. We have discarded it as 
far as possible, because we have proved that the tubular 
construction is inestimably better than a wall of fire-bricks. 
First, the latter are bound to get out of shape by con- 
tinued use. Second, the rounded tubes give two-thirds 
more radiating surface than a flat wall. Third, the tubes 
through which the flames pass are made as thin as possible, 
so that the heat is sent directly into the oven, instead of 
having to first heat through a heavy brick wall. 
The No. 6 is the most popular size for Studio Work.
