I am, after all these years, building my very own raku kiln as opposed
to using kilns of others. I have encountered many different types,, and
have settled on making mine using the upper half of a 55 gallon drum.
The bottom part of the kiln will be stacked brik - a combination of hard
firebrick and K-23 refractory firebrick. The upper part will be the 55
gal drum with refractory fiber as the liner for the sides and top.
Question:
Would it be worth the trouble and expense to spray the fiber in the kiln
with ITC?
Thanks,

If you opt not to use ITC then consider using sodium silicate as a
rigidizer. It has worked well for me.

John,
In one word absolutely. Do treat it with something; untreated fibre whateve=
r its type degrades rapidly with a live flame, putting Fibre Dust into the =
air and potentially into your lungs. Whether it is the so-called "safe" or =
unsafe one, it ain't going to do your breathing system any good at all.
Here it the UK we use a colloidal silica which can be diluted (though I don=
't!) and sprayed onto the fibre. It contains a wetting agent so that it com=
bines with it, unlike a lot of other "treatments" which sit on the surface =
and ultimately fall off taking some of the fibre with them. Here it is call=
ed Kaowool Hardener.
Usual disclaimers, I just find it's the best stuff for the job, and the sur=
face can be re-sprayed when (inevitably) it starts to get a bit worn with u=
se.
