either that or fireclay as a thin (ish) slurry

Using house bricks in that kiln design is fine for lower temperatures, but
they are not efficient insulators and you will need lots of fuel -
however, it's a great learning tool.

You will need to use some "mortar" to seal the brick joints so that cold
air doesn't get in after the firing is finished and crack all your pots.
Old clay slurry is quite suitable and cheap.

I've been waiting to see responses on this thread in anticipation. I
have a stack of low fired patio type or house bricks and have been toying
with building a small wood fire kiln but thought the bricks probably not
usable. I will now jump in and give it a try. Thanks!
