Dear Mel,
How does Itc work as a release agent on the shelves? Should kiln wash be
used over it? I use Lee's kiln was and love it for both its lack of
flaking and it's ability to help stuck things release.

Linda : Please don't put kiln wash over ITC 100. Use it as the kiln wash.
You won't need to use Lee's kiln wash and you'll get the added benefit of
a reflective surface- hence energy savings!! We use ash glazes almost
exclusively and hence often have runny glazes. if we have to chip a pot
from the shelf, we paint on some ITC l00. patch the hole and smooth over
with ITC 200 patching compound and spray some ITC l00 over again for kiln
wash. While you're at it, I would recommend that you spray the entire kiln
with ITC 100. We did and we wouldn't have a kiln without it.
Long may your chimney smoke!

Dear Shiela,
Thanks for the info. I did spray the kilns with ITC 100 but had not done
the shelves because I wasn't sure it would release in case of a run.
However, I must say that lee's doesn't release well either. I guess I am
wondering about this. Regular, flaky kiln wash was a problem, however,
stuck things usually released better. When something runs and it removes
part of the shelf when you get it off, there is obviously a trade off.
Shelves for saved pieces that don't get flaked on. Probably when it comes
to release, the ITC 100 might be equal to Lee's. Any thoughts from your end
on the question of release and ITC? Sounds like you just fill the pits. I
have the filler from ITC and just hadn't thought to use it this way.

Dear Linda: Yes it is a trade off. With some of ash glazed pots where
there seems to be built in areas for the glaze to run we have taken to
wadding the pots as if for salt glaze. Also a generous footring or a
profile rib has helped some. If the ITC is sprayed it won't release very
well since it is such a fine coat. A painted coat might be more suitable
for releasing the glaze drip. The ITC is expensive so we all tend to be
frugal. But then shelves are even more expensive and our pots are worth
something too! We just tried using the ITC 200 filler compound intead of
Bray patch on a jug handle that had pulled away. Worked well in the
bisque but we have yet to glaze fire it! No we haven't
tried the ITC on dessert yet. However I am going to try mixing ITC 100
with feldspar 50/50 for salt glaze.

Hi Linda,
Can you elaborate a bit? If the kiln wash doesn't release (as in Lee's),
and part of the shelf comes off, what do you fill the pits with? Is there
an ITC filler for that purpose?
Thanks. --Gail Dapogny in Ann Arbor

Dear Tony,
I am still thinking about this kiln wash/Lee's/ITC for shelves. As I said,
Lee's doesn't release. Sure it doesn't flake, but by not releasing,
doesn't that (Lee's lovers, I am asking all of you) make it about equal to
no wash? I was also noting Tony's note that the ITC is a thin coat. I had
sprayed both of my kilns wit it and in the gas I sprayed the fiber layer.
It was a little stiff but you could break through the coating. THen a
friend got a sample of sprayed fiber from ITC and it was HARD. You could
not break throughthe coating to the fiber. So the directions that said to
spray a thin coat meant a medium coat? Anyway, it is apparent that I
didn't spray enough. Anyone else figure out what a "thin" coat is? I
guess if nothing is going to release, then the reflectivity is an
advantage. I will use the ITC patch for the holes once I grind off the
glaze around the edges of the pits. The four inch angle grinder is a
ceramicists best friend.

Linda,
The Lee's kiln wash does seem to release for me, at least with a bit of
effort. I had trouble at first, but just assumed I had put it on too
thin, so I reapplied for a thicker coat. Glazze drips do need to be
chiselled off, but the wash seems to come off without pieces of the shelf
coming with it. Maybe you need to apply it thicker :)

yes, go for it.
i use a paint brush.
just slather it on.
thicker is ok.
i use a mix of half and half/water and itc 100.
on silica carbide it won't sink in...it will just dry
on the surface.
when you bisque the shelves it gets as hard as rock.
remember to do the edges, top and bottom.
the entire thing.
you can second coat as needed...i do not bisque
the touch up second coat.
just paint it on.
we sprayed the shelves at the farm.
just line em up...hit em hard.

joyce/do those shelves...itc does not work in the can.

there is a great two part photo in nils` book.
he fired his wood kiln with a kiln shelf sitting
in the fire box with a block of 25# clay sitting on the
shelf. a brick holding it up on each end.
after the firing it was bent in half. shelf was a total U
another, same shelf, coated with itc, another block of
clay, fired to cone 13 or so in the fire box.
not a bend. flat.
does it work...???you bet. look at the pix....
we coat all of our shelves.
as i told steve slatin.
i really don't give a p about doubters. i will not argue
with them. use or not...not my issue.
it just works great for us.
we tested it now for 15 years.
i coat everything...thin coat of itc 100
(google it, or axner it...it is in the archives
by the thousands.) a gal coated her muffler.
doubled the life.
kiln coils double in life.
thermocouples last forever.
shelves go forever.
nothing sticks.
i do not need to coat advancers.
but, i did. works fine. long slow bisque firing
to dry them totally.
the best use is spraying fiber.
makes a really nice coating..tough.
nothing gets to your lungs.
itc leaves a coating of hard brick on a soft brick.
makes a micro surface of hard brick, reflecting heat
back into the kiln.
increases the k factor.
it just does...and i don't have a big secret to share.
it works.
nasa thinks so, the u.s. military thinks so.
alcoa thinks so.
and we do not care if some potter thinks it is phooey.
their loss.
