For those of you building a stoneware kiln, my Flickr site has 2 similar
floor systems shown on it. The system makes for good reduction and for
even firing. I have used the floor system since 1966 and have good
results from the first firing in a new kiln..

many will give this same advice...we have already heard from
quality kiln builders. here is a summary:
without question, kiln floors, around flame ports, and flues
are best done with hard brick.
no real economy is gained by using extra soft bricks
in these areas.
the beating these areas take will cost you far more
to replace.
in our plans we have the kiln built with two
layers of soft brick under the main hard floor.
so, the floor is four brick thick.
we suggest using used, even beat out soft brick
for the insulation in the floor.
no need for new.
save that for the roof and sidewalls.
chimneys must be tight, and good hard brick
can be used there...mortar it tight.
ps. never use sand or other material
to fill the cracks in the floor. it just spreads
the brick and leaves larger cracks.
pull everything tight and use good metal framing
to keep it tight. here is where aircraft cable held
together with a screw in clamp/ turnbuckle system works great.
get it at the hardware store.
