I would like other pottery ppl's advice as to what to do about this
problem.
I'm sure some of you have quite a lot of good ideas about this.
Every glaze firing, the pots in the top of the kiln have to be dremmeled
and refired because of kiln bits in the bottoms of bowls. Short of buying
and extra shelf and losing the top few inches of the kiln, what can be done
about this?
I noticed the problem awhile ago and i am extra careful when lowering the
lid, but i still get them... nasty little kiln bits.... i tried vacuuming
the lid, but that didn't help.
Is there something i can put on the lid, some kind of sealant?
Thanx for the helpful advice,
Anne,
in Saint-Sauveur, where i am so relieved that Clayart is back, i was really
quite worried that something had happened to Joyce over the weekend!

Anne, Calculate the time wasted (worth $'s), and the actual dollar expense
of pots not made while you fuss with damaged ones, + fuel + +!! not to
mention what else you could profitably and creatively focus on instead of
the frustration you express.
How does one inch lost + the cost of a new shelf weigh in? Or...
A new lid is only a couple hundred bucks and you would make that back first
fireing. Plus you get the satisfaction and pride that you took care of the
problem in a business like and professional manner. This is priceless and
leads to other great creative thoughts and action.
Sincere regards,
David

There are several reasons firebrick pieces fall from the
lid:
Pieces fall out of lid cracks: Stuff the cracks with ceramic
fiber. Use a screwdriver or wooden tongue depressor to
insert the fiber.
Pieces fall from a deteriorating lid surface rather than
from cracks: Lightly sand the lid to remove loose firebrick
particles. Then coat the lid with either liquid kiln coating
or watered-down repair cement.
The lid surface is peeling: When kiln coating is applied too
heavily to the inner lid surface, the coating will flake off
onto the ware. Sand the coating and follow the instructions
below.
Repair cement:
Mix to the consistency of coffee cream. Wipe it on with a
paint brush, and then immediately wipe it back off with a
rag. Though it will appear that you have removed all the
coating, it will actually fill the surface pores of the
firebricks. Allow the cement to dry completely before firing
the kiln.
Liquid kiln coating:
1) Shake the container until the coating is thoroughly
mixed. Pour some of the coating into a bowl. Stir the
coating just before you apply it to the lid.
2) Apply the coating with a large, soft sponge such as the
type used for wallpaper. Moisten the sponge with water; then
squeeze out the excess water.
3) Dip the sponge into the bowl of kiln coating. Wipe the
coating over the lid surface. The coating should be thin
enough so that you can still see the brick seams underneath.
4) Allow the coating to dry completely before firing the
kiln.
Anne, please let us know how you solve your lid problem.

Hi everyone and thankyou for the helpful suggestions.
I thought this happened all the time cause i read in the kiln manual that
lid and floor cracks would develop over time.
As this is a brand new kiln i guess i should contact the maker first and
see what they suggest.
Thanx,
Anne

The kiln may have been damaged in shipping. When you receive
a kiln, open the packaging and inspect the firing chamber.
If the truck driver cannot wait while you inspect the kiln,
sign the bill of lading with the notation "subject to
inspection, driver refuses to wait." If you discover
shipping damage after the driver leaves, you have a better
chance of being reimbursed by the trucking company.

Hi Howard,
the cracks in the kiln lid didn't start to appear until after the first few
firings, same time as the ones in the floor. i fired to cone 10 for my
first glazing and had done the prefire when the kiln arrived and a bisque
to cone 05 after that.
We checked the kiln really well when it arrived and it appeared
pristine.Thanx ,
Anne

Thankyou to everyone who responded on and off-list with their helpful
suggestions.
I had thought this was something everyone dealt with and was a common thing
with kilns and that there was a common fix for it.
Upon careful consideration after reading all the different suggested fixes
for this problem and not knowing which route to go, i put a call in to the
dealer i bought the kiln from this morning, Don Seymour at Clayscapes
Pottery and he was very helpful in this matter. He got through to the tech
person at L&L (Hi Rob!)and the good folks down there will be sending me a
package with some mortar and facing compound. Apparently it is not
difficult to do and will resolve the issue.
Again, thanx for all the help, and i can't say enough good things about
this kiln so i'm glad it will be an easy fix.
Anne, in Saint-Sauveur, where its warmed up to minus 11c... and the
sunshine on the fresh snow is absolutely gorgeous!!
