I'm rebuilding an old salt kiln and need some resource information.
I am looking for bricks for my salt kiln door. I used to buy Babcock &
Wilcox K-23's which resisted salt fumes. Does anyone know if they are still
available or if some other manufacturer makes bricks to that formula now?
Also can anyone supply a good recipe for home-made castable to use on top of
the kiln. It will be above 4.5 inches of hardbrick and 1 inch of fibre
insulation.
Thanks,

Why would you want to kill the insulative properties of the fiber
by covering it with a compacting element like castable??
Hmmm.

I wrote a few days ago asking for a recipe for home-made castable to put on
top of my old salt kiln, and got the above thoughtful response from Alex
Solla.
Thanks for the question, Alex. Here's my situation. My kiln and kiln shed
are old and leaky, and I have neither the money nor gumption to take
everything down and start anew right now. So I'm trying to make due with
patch-up repairs. It's hard to know how much to put into this -- a bit like
deciding whether to replace a transmission in a ten-year-old car with 150k
miles...
Anyway, we peeled off the old cracked and messy fibre and insulation from the
walls and arch and put on a new inch of fibrefax on top of the 4.5" hard
brick arch. Now I'm thinking that a layer of castable will 1) protect the
new fibre from the inevitable leakage, wind, and weather and 2) reduce the
flame and salt leakage from within through the multiple cracks in the kiln
walls.
So I'm still looking for a recipe for castable to use on the kiln walls --
and I also want advice/comments on whether you guys think it's a mistake to
use castable on the arch on top of the 1" of fibre. (The new fibre seems
quite dense; it doesn't compress easily to the touch, unlike my old stuff).
Know anyone who's done it? What do you think?
Thanks.

Nan,
Sounds like you might want to check out the cermamic coating from ITC. They
have an ad in CM. Their phone # is 904-285-0200. I've purchased a gallon of
the stuff, but haven't applied it yet. According to ITC, it will provide a
thin, protective coating over fiber and provide additional insulation.
