Craig,
Tony Winchester made a salt kiln using itc out of an old skutt or something
like it. The pieces were pretty sweet actually. He did it as a test and I
think was pretty satisfied--I saw some of the pieces and they were pretty
nice. I heard Bob Briscoe built a soft brick kiln and sprayed with Smith
Sharpe's special 95% zirconium silicate + 5% binder--I have not seen his
kiln or talked to him--perhaps he will chime in.
I have been working on (back burner presently) on a modular fiber-gama and I
am waiting for the ITC and Smith Sharpes product to improve (accorind to
heard testing) as I will attempt to woodfire in an all fiber setup
eventually. Apparenlty both products currently do not handle the air born
caustic nature of the alkalies (according to Sharpe's data sheets/research)
ash and salt. I hope to test both products in the regular woodkiln until I
am satisfied and then build the fiber-gama for a 30 hour test run. I am
presently trying to get a hold of the tile engineers and some 3M folk to try
to see if they will consult with me regarding a material that will protect
the fiber from salt, wood ash, alkalies, gaseous environment, etc.
You may be thinking, "why fiber." I think, "why not." A kiln you don't
have to climb up into to load--yeah, baby!
Thank you.

Subject: ITC for salt firing?
I've heard that ITC will protect soft brick in Salt Firings. Is this
true? The reason I'm asking is that students of a friend at a local school
used ITC to treat the soft brick in a small updraft kiln in an attempt to
use it as a Salt Kiln. THe results were not good. The brick started to flake
away after the first firing. He thinks that it could possible have been the
application, or possibly the use of a considerable amount of salt to season
the kiln. They used about 14lbs. The salting process was done using angle
iron through ports above the burners and through ports in the door. Does
anyone have any experience with using ITC on soft brick in a salt kiln?
Thankyou

Craig -
No, unfortunately it does not work in salt kilns. It works pretty well in
soda kilns, but that is a milder atmosphere. We get great results in our
softbrick soda kilns, but they are throw-away kilns after about five years
of heavy use. It is worth it to us.
