I recently used the quart of ITC I bought a year ago on my fiber raku
kiln, I used a compressor, the spray attachment I ordered from Alice, and
felt that I did I pretty good job, inside and out, top and bottom....the
kiln top loads. The kiln was a couple of years old, but not pilling, or
dropping fiber of any kind. After 6 or 8 uses with the ITC the ITC is
flaking off if it is barely touched, and small pieces of the kaowool are
dropping off the lid, which is lifted on and off repeatedly.
I see my future as (1) building a new kiln and (2) spraying the new kiln
with ITC first. But in case I am missing something that would insure me a
job well done I thought I would ask the list ( and Mel of course) about
what is going on. Thanks in advance for any thoughts on the matter.

=3ESandra - Late this past spring, the powers that be, at the school
where I teach, actually gave me money to buy a new electric kiln, the
amount I had asked for. So I researched around and found I could get an
electric kiln that I wanted and a raku kiln for the money they were
willing to spend. I got a new fiber kiln, larger than the current one
(that I've replaced the fiber in two times over the 12 years of use -
getting kind of ragged). The kiln was sprayed all over, inside and out,
with ITC. After about 5=9610 firings I noticed the inside was developing
cracks in the surface. Not too long after that I noticed the ITC
coating was coming loose from the interior top, near the flue. I pulled
on it slightly and the whole inside coating of ITC came falling off=21 I
reported this to the kiln supplier and they sent me a pint of ITC to
respray on the fiber. I haven't decided if I'm going to re-spray the
ITC on. I do have ITC on the electric kiln and have not had any
problems with it coming off, but I'm wondering if there has been others
with problems of ITC coming off fiber.

I have a fiber kiln and I was thinking of coating it with itc, I contacted
the manufacturer of the kiln and they recommended against it because of what
happens to the fiber as it changes during repeated firing, and what they
said is what is happening to the fiber, that the itc coating is releasing,
this is happening because the fiber melts back onto itself, the kiln/glaze
gurus will have the proper termology for this process but what happens is
that the fiber looses its ability to hold onto itself, so it lets go,
spraying itc probably just adds weight and makes it happen faster
I am interested in other peoples opinion

Hey y'all,
I have found that using I.T.C. topcoatings on fiber that has been used will
ultimatly fail. I believe that this is due to the friability of the fibers
after high firing.
When I have applied I.T.C. to new fiber using the proper techniques, I have
found that the coating will last a very long time.
When applying the coating always start by spraying the interior of the kiln
with a generous amount of water... not soaking but nearly so. Then, thin the
coating down a bit with water making sure that *EVERY* particle is in
suspension. Then spray the kiln completely with several light coats instead
of one heavy one. After spraying it may be helpful to gently compress the
damp surface of the coated fiber to smooth any fibers that may be loosened.
After allowing the kiln to sit open until dry to the touch, you may fire it
slowly to bisque temp. This will allow the coating to harden before being
exposed to possible damage.
These steps have worked for me, I hope that they will help y'all with your
troubles.

Thank you to all who replied. I think the combination of older fiber and
a particular "shyness" on my part when spraying the water on the fiber
may be the key to this learning experience for me. I will begin again
this winter, once the shows stop , and do it right. Thanks again.
