Funny you should ask...

I'm in the middle of building an electric kiln. Not the easiest
project I've undertaken.
The overriding problem I've encountered thus far is dust. But the dust
is due to the fact that I elected to build a round kiln. This would
be alleviated completely by building a square kiln.
If I were to build a square kiln without a metal frame I would without
question use mortar. But mortar is very hard to use. You must only
use it in the final position of the kiln. Mortar the bricks in the
final resting position, then fire. THe mortar has virtually no
strength before it has been fired (such has been my experience).
Regards,
Mark.

Hello,I am experimenting with clay and simple kilns,had some succes with a
small simple gas fired kiln,but because of some considerations,I find that a

Here is my question.I have seen that electrical kilns have some kind of
metal frame.I suppose its purpose is to hold all bricks in one form?Can a
kiln be made by only assembling bricks without mortaring them and without

The biggest problem I see is that if the kiln doesn't have a frame, then
things will be loose and shift easily. The electric elements tend to become
brittle after firing and moving them around might cause them to fail sooner.

A few pointers on cementing bricks:
Apply cement to both brick surfaces by
dipping the bricks into a large tray of
cement.
Slide the cement-dipped bricks together back
and forth to get a tight seam. The seam
should be about 1/16" wide. Thick seams tend
to fail.
After the brick pieces are pressed together,
do not disturb for 24 hours.
