I would like to move my electric kiln into this porch I'm going to convert into
a studio. The porch is definitely attached to my house--and although one wall
of the porch is brick, the rest of the porch is not. Can I use some
kiln-insulating material on the walls of the porch to prevent the heat from
burning up the porch---or should I just forget trying to move the kiln inside
the porch? Is this a fire waiting to happen?

Hi Sandy,
Transite board works well for this application......or old house bricks.

one idea...not the only idea I am sure...someone sent me to Home Depot (do it
your self home store) for the fire board builders use behind wall in and
around fireplaces...it seems to be concrete type material which is easy to
score and cut to the necessary sizes and shapes...
lets see what other people suggest...

i would also research venting the kiln to the outside...

Several years ago we had this exact same arrangement. I screwed cement
board onto the wall using 3 1/2" screws. A 2" piece of copper pipe(it was
handy) held the board 2" from the wall. This arrangement worked fine for
me.
One day during a firing about two weeks later on whim I felt the floor
underneath the kiln. OOOUUUCCCHHH! it was hot. I thought the stand was
elevating the kiln high enough so that it was safe. Heat rises
right...wrong. I sat there until the firing was over with an extinguisher
waiting for the floor to burst into flame(slight exaggeration). Using
bricks and some more cement board I created a similar structure. The
bricks placed under the board where the kiln stand legs sat on the cement
board and any where I might step on it. During subsequent firings I
checked floor and wall and they were never even slightly warm. I never
have told my partner how hot that floor was.

how about the panels made for setting a wood stove on?

Sandra- I have a small kiln set up in my frame-constriuction studio, and
have fired it OK to cone 6 a number of times. I NEVER fire it without
being present, but I have had no problems with the system I use.
First- the wall around the area is of heat resistant wallboard ( a gypsum
product) and is not painted. The kiln itself sits on an old kiln lid, from
a larger kiln, to protect the floor. However, the major protection to the
walls is from a metal jacket on the wall. The idea came from a system used
to protect walls behind wood stoves. Even so, the kiln should be away from
the wall as far as is possible.
For the space from about an inch above the floor to about a foot above the
height of the kiln, there is a sheet of corrugated , galvanized, sheet
metal, of the type used for farm shed roofing. This is held away from the
wall at least an inch by using tubes through which the screws holding the
sheets up are run. The bottom edge of this sheet metal is above the floor,
by about an inch, in order to let the air enter the bottom, pass up the
space behind the sheet metal, and out the top. The heat that gets to the
sheet metal will heat the air behind it, and cause the flow to happen
naturally. This air circulation keeps the wall cool.
An additional benefit of the sheet metal is that it is reflective, which
also keeps some of the heat away from the wall. Having a larger sheet of
flat galvanized metal under the kiln also helps by dissipating the heat,
that would otherwise hit the floor.
I do not really like to use a kiln close to wood construction, but
sometimes we pay the price of extra watchfullness for the
possibility of firing at all. KEEP SEVERAL FIRE EXTINGUISHERS handy.
Good luck- Bill

I do not think that transite board is still available since it is made of
asbostos. There is now some stuff called "wonder board"..... concrete board
with fiberglass inbeded in it used in shower walls to mount tile ..... found
in lumber yards or good hardware stores. But do not mount this or any board
directly against any combustable material.....make an air space between the
wood and the board using washers or metal nuts to help keep the hot board away
from the wood. Also mount the board a few inches off the floor to increase
the free flow oof air.
Good luck

An additional bit of information about wonder (concrete) board. I have done
five tile installations and you will need a good bit of support under the
wonder board. Just mounting it on an 18" centered stud wall, it will bow.
I'm sure the weight of the kiln will rip right through it unless you have
carefully placed supports under it. Just FYI
