If you be cunning tho' you can get house bricks that fire quite high...
Glouscester golds from Ibstock (UK brick maker) will do 1350 deg C + and not
melt.... You can use them and make a fast fire kiln which gets round the
probs of low insulation... (See Steve Mill's super kiln) Alternatively you
can use a double skin and fill the gap with soil (bloody good insulator is
dirt....)

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!
