kiln repair-broken brick

I have a question about kiln bricks. I broke a chunk off of the top brick o=
n my
kiln. I guess i must have habitually leaned over to load the bottom shelf i=
n the
same spot over and over. The chunk is about 2 inches and now exposes the co=
il
element. It did not damage the element but it no longer is nestled in the
"grove" between bricks. The lid still closes fine and as it is the inner ed=
ge of
the brick i figure it will not impact heat escaping the kiln lid. Do i need=
to
fix this? If yes do i need to replace the entire brick or is there cement t=
hat i
can piece the chunks back in?

Thanks
Dana

The simple answer is yes, the brick can be cemented back in place, but if
you will continue to lean over that spot, it will probably break again.

You write: "It did not damage the element but it no longer is nestled in
>the "grove" between bricks." If the element is still laying in the groove,
and the bottom of the groove is still intact, you can probably use a couple
element pins to secure the element in place.

I would suggest leaving as is, sanding off any loose/rough edges of the
broken brick, vacuuming out all chunks/brick dust, putting a thick towel
over the area when loading/unloading to prevent further damage.

You can replace the brick when replacing elements. Just loosing the metal
skin and sliding brick out, sliding in new brick.

FYI - I have several short female students and a couple tallish top loading
kilns. I put cinder blocks on floor both sides of kilns. This allows shorte=
r
persons to more easily reach down into kilns.

I agree with Bill. As long as 1 1/2" of the damaged wall brick surface
is left to contact the lid, you do not need to replace the brick. The
photo at the top of page 3 illustrates this (see link below):

Here is an article on reducing damage to the top rim of kiln wall bricks:

My kiln has had the same kind of chip in the top=3D20
rim for twenty years, no harm done. It was there=3D20
when I bought it, but with a new kiln I might protect=3D20
it. It's a very common phenomenon for top-loading=3D20
electric kilns. I don't think it's loading that does the=3D20
damage in most cases, but rather the way that the=3D20
prop is set when keeping the lid partially open=3D20
during candling.
