Stephanie- With your lid down before a firing, simply dribble liquid
collidial silica into the crack(s), do the firing, and voila! The lid is
fixed! If it cracks again, it is unlikely it will be at the same location!

Take note that "collidial silica" is "sodium silicate" which has gone
through a negitive ion process and is at least 100 times more effective and
durable.

A classmate of mine recently got an old electric kiln. She said the
company that manufactured it is supposedly no longer in business (Stewart,
she thinks). The lining of the kiln needs repair, as it is cracked and
chipped in several spots, especially on the lid/cover. She has looked at
several patching compounds meant for this purpose, but the directions all
say specifically not to use the compund on the kiln lid. Does anyone know
what she can use, or another way to repair the kiln that is safe and cost
effective?
Thanks for any suggestions!

Gouges and cracks in the brick walls and floor can usually
be left unrepaired. They rarely affect the firing results.
If an element is bulging out due to a damaged element
groove, you can secure the element with a pin. That takes
only a moment.
Dust can fall from cracks in the lid onto the ware. If you
fire only greenware, the dust won't matter. To prevent
dusting, press ceramic fiber into lid cracks. (This is one
of Mel's remedies.) Vacuum the lid. Then roll the fiber into
a pencil-like strand and press into the crack with a knife.
This works only for cracks at least 1/16" wide. Thinner
cracks won't accept the fiber.
Finer cracks can be vacuumed and treated with sodium
silicate. (Has anyone on the list tried that?) It leaves a
gray discoloration but hardens the brick surface. Squeeze
sodium silicate up into the cracks with a syringe. Or remove
the lid, turn upside down, and drip a small amount into the
cracks.
Smooth gouges in the lid with sandpaper to remove loose
brick particles. Vacuum. Mix brick cement to the consistency
of coffee cream and brush onto the gouge with a paintbrush.
Immediately afterward, remove the cement with a rag. This
will leave only enough cement to fill in the surface brick
pores to help prevent dusting.

What is the lid made of? If its just an insulating brick, I have a mortar
that would be perfect for that. I sell 4# of it for $7. That should be more
than enough for a repair. Please advise I'm sure I can help her.

I used colloidal silica mixed 2 parts CS to 1 part each kaolin and flint,
by volume. This made a creamy less watery material to fill cracks in
my kiln lid. It worked beautifully.
