fwd: treating new elements with itc 213: exactly how?

just a word of caution - if you don't do it right stuff will flake off
everywhere and ruin lots of pots.
i dipped my elements for my bisque kiln - i didn't really care if it flaked
off since i never fire glazes in there.
i bisque fired the elements first (still wrapped in coils on the bottom of
the kiln) then followed all the instructions - diluted the itc just right,
etc. Didn't seem to be on too thick but i had black stuff coming off for a
long time - at least a year, maybe more.
It's a pain to do, time consuming and rather expensive.

on the other hand, i sprayed the inside of the kiln and also my gas kiln
with the 100HT and it seemed to work just well - none of it came off and
the bricks seem to be in good shape after hundreds of firings. My old
bisque kiln had well over a thousand firings before i coated it and was
basically shot and since then i have done hundreds of bisque firings (and
also re-wired all of it, replaced the kiln sitter and the lid!) and it is
just fine.
