Dunno about ITC. When I did chemical patinas on bronze
for 8 hours a day, though, the exhaust fan of the patina
shack would corrode into metal lace in a year or so. So,
the last time I replaced it, I sprayed it with clear
spray paint. (Could've used a color, I guess; clear was
what I had on hand.) It lasted about twice as long as
its predecessors. I don't know about protecting an
actual motor, but I assume it's the fan blades that are
most vulnerable on your vent.

Hi All,
After 7 years of faithfully protecting my kiln elements from multiple weird
experiments, a dreaded fluorspar glaze which I use often on decorative
pieces and normal old run of the mill stuff, my Envirovent bit the
dust.....literally. After a two month hiatus, I turned the vent on only to
hear the most awful clanging of metal and to see bits of something trying to
escape out of the side of the aluminum vent which runs up the wall. The fan
blades in the motor just disintegrated into small flakes of really corroded
metal. What was left on the motor looked like it had been dipped in acid.
I fired all during the Christmas rush without the vent which made me
remember why I got the vent in the first place....the firings are so uneven
without that thing. I was told that the corrosion is common and some
potters replace their motors every 2 or 3 years. Well, I've got to get a
new motor and was wondering if anyone has tried coating the blades of the
motor or any other part of a vent with ITC. Does it stay put or would it
just fly off the blades after a while? Would the vent get hot enough to set
the ITC? I realize I'd have to be very careful to avoid gunking up the
works, but it seems like the ITC would really help extend the life of the
blades which is what seems to really need the protection since the motor
itself is still working. I've checked the archives and found potters
putting ITC on all kinds of stuff, but I couldn't find anything on vents.
Any ideas all of you long time users of ITC?

Carla,
I don't see any reason why you could not coat the fan blades with ITC -
there is 100 and then 213 which is for metal. I had 100 on my elements and
I never did see any degredation on them. I would think that either one
would work but 213 comes in smaller quantities so maybe that would be better
in this case.

They already buy it from Feriz. Its on the shuttle. Also protects other
equipment during launch. Feriz's degree is in Ceramics Engineering. Its good
stuff.

Gayle,
The temp on the front of the space craft reaches 15,000 degrees--I don't
believe ITC would help them, but I could be wrong.
Thank you.
