kiln on wood floor

updated mon 15 apr 02

 

Anne Wellings on fri 12 apr 02


I have a 7 cu. foot electric kiln on a wood floor. I'm sure the way I deal
with it isn't the best, but it works in a pinch. I have piled up two layers
of old soft brick pieces under the kiln so that none of the floor is
exposed. These are mainly sections of a broken kiln lid with other soft
brick pieces from a blown-out gas kiln arch on top of that, so it's all
recycled materials and nothing I spent money for. I have felt the floor
often to see if it's getting hot, and it doesn't. However, I know it would
be better if this arrangement extended further out from the base of the
kiln, so I am just very careful and never fire the kiln unattended or
without a fire extinguisher nearby. (Hot peep plugs can fall out, etc.)

I'll be moving my kiln soon to a place with a linoleum floor, which I guess
is better, but I will still pile up the soft brick under the kiln. Or maybe
I'll try one of the suggestions below.

Anne, this is a truly bad idea. On the premise that the floor is checked
and it is not getting warm, the idea at first sounds reasonable. I was
in a four person studio many years ago with a bisque only electric kiln
sitting on a thick layer of insulating firebricks. This kiln was fired
fairly regularly by us and checked fairly often, but the wood floor had
dried out to an almost spontaneous combustion state. One night before
leaving I smelled a very slight smell of something smoldering. I looked
everywhere and could not find a source. The kiln had been off for
several hours. Still smelling the faint odor I looked in the basement
one more time and when I got directly under where the kiln was, the
floor was a glowing circle, funny about the diameter of the kiln
upstairs! We moved the red hot kiln and poured much water on the embers
to successfully put out this dangerous situation, made more critical by
the fact that two renters lived on the third floor. Please put this kiln
on a stand with air between it and the wood or linoleum. I would also
recommend a non-combustable reflective shield about 1 inch above a layer
of insulating firebricks on the floor and a several inches below the
kiln bottom. Sincerely, A very lucky, Robert Briscoe

> With some white grogged stoneware clay I've been using recently, if I want
a smooth, satiny finish, I will first prepare slip that has the grog removed
by settling. Then I wait for the pot to dry to a soft leather hard, then
smooth the surface with a flexible stainless steel rib. This compresses
grog particles into the clay. I then let the pot dry almost completely, and
brush on three or four layers of the slip, wait for it to harden a bit then
smooth the slipped surface again with the stainless rib. Finally, I burnish
the surface with a piece of polished stone or glass. When the pot is bisque
fired, It will lose its shine, but have a very smooth even satiny surface.

Thanks, Robert,

I guess I should have been more clear in my description by saying that the
kiln is indeed sitting on an official metal kiln stand, and the layers of
soft insulating firebricks are piled up on the floor under that, with
several inches of air space between the bricks and the bottom of the kiln.
I guess I assumed everyone used kiln stands and it didn't occur to me that
anyone would use the soft bricks themselves as a stand, especially on a
wooden floor.

However, your account is a true horror story, and it's good that you told
it. I now feel like going under my house and checking the bottom of the
floorboards for any sort of circular discoloration. Also, your idea of the
non-combustible reflective shield is very good, as are some of the other
suggestions given recently.

When I move my kiln, I will give serious thought to a different plan.

Anne
