hello all
have built a raku kiln out of an old, square electric kiln ... the hole i cut
in the top lid is, literally, crumbling - if i'm super careful when lowering
the lid it's no problem.
....HOWEVER, i am about to do the same thing on a kiln for a classroom
setting... and was wondering if there is anything (besides ITC) that i can put
on the brick and such to keep firebrick dust from falling into the kiln and on
pots?
thanks in advance!!!....hank (in oklahellma - where it's one hell of a
summer!)

Hank,
I'm not speaking from experience here, but I think just
coating the bricks with mortar would help keep them
together.
Mix up a batch of half fireclay and half grog. Ground up
insulating bricks (window screen mesh and smaller) make
great refractory grog and it sounds like you have some wasters.
Add sodium silicate. I don't know exactly how much, about
a tablespoon per gallon, but you'll know if you add it slowly
while mixing. The mix will suddenly become much more
fliud. You may have to add more clay to stiffen it up again.
Wet down your lid and put on a thin coating.Trowel a little
extra around the cut-out area.
Again, I've not actually done what you're wanting to do,
but this sounds good on paper.
Has anyone tried something like this?
