Hi,
I wanted to report on my ITC experience. I have a 40 cu. ft. softbrick wood
fired kiln. Two years ago I sprayed the interior with a zirconium oxide wash
because I intended to start salting (5=23 per firing) . It lasted pretty =
well but
the bricks near the firemouth started to spall. It looked like I would have =
to
rebuild shortly. Then I read about ITC. I scraped down the crumbly brick to
solid material and sprayed the whole interior with ITC100.
I just unloaded my 3rd firing yesterday and a couple of the bricks are =
starting
to spall again. The ITC made a nice hard coating on the rest of the kiln but
some of the damaged bricks are continuing to crumble. The chunks coming off =
have
a hard shell on them. I dabbed the exposed areas with the zirconium again. =
(I'm
out of ITC).
I'm sure the kiln will last a lot longer with the stuff. Maybe I was asking =
for
too much for it to arrest the spalling problem.
I was also told (by Axner) that it couldn't be sprayed over previously =
salted
bricks. That it wouldn't stick. It did fine on the soft brick. I'm not sure =
how
it would do on hard salted brick.
About brushes: Citra-solv (the citrus solvent) cleans both kinds of wax from
brushes. (It's amazing goo.)
That's it for now.
Cheers,
