Neal -
What you have there is an old DFC "muffle kiln." The burners direct the
heat through the refractory tubes, from which the heat radiates into the
kiln (in theory). The reason for this elaborate setup was to protect the
wares from the flames and atmosphere. Such kilns are obsolete, except for
very specialized firing in industry, and they are extremely inefficient to
fire. You could probably just remove the muffles and convert the kiln into
a decent updraft.
Good luck -

cool, museum piece! Pre-reduction DFC kiln! Flames went the
tubes and radiant heated the firing chamber.

Hi everyone.

This is my first message on the Clay Art. We have found an OLD Gas Kiln in
a friends house. It was made by the Denver Clay Co. and is called a "Keramic
Kiln" we have not been able to find a date on it yet. I have done a bit of
checking around and can not find the Denver Clay Co. The kiln is about 3' x
5' outside dim. and 16"x2' inside dim. There are pipes running through the
inner chamber and I can not find any gas ports. Does anyone have any clue
when it was made, if the company is still around or any information at all
about it. If you need more information please ask. I will be patiently
waiting.

Bye for now,
Neal

Denver Clay Co, also know as Denver Fireclay is no longer in business. They
made one of the first gear reduction potters wheels with solid bronze or
brass wheelheads. These were AC motors with speed reducers, I used one at
RISD and the foot pedal was atatched to the controller with a chain. Always
wondered how they figured out to control the speed on an AC motor.
Tremendously powerful wheel with a very sensitive foot pedal. Sounded like
a Mack Truck though.

The kiln you have is a muffle kiln. The tubes contained the flames as the
kiln is an updraft with the burners on the bottom shooting upwards into the
tubes.

On the other hand, the tubes could be GloBars and it could be an electric kiln.

It looks like you have found an old muffle kiln. The heat went up through
the pipes giving a good radiant oxidizing fire. The heat probably came up
from the bottom of the kiln. With a little ingenuity you probably could
convert this thing to a regular reduction firing after removing the tubes.
