dan,
we got our bricks from the local harbison/walker dealer and paid about
$1.50/brick for K23's they were also from china, but they seem to be
decent bricks. have not fired them in a kiln yet to test, but we are
not unhappy so far, they seem as durable as any other soft brick I
have used. I would use k28's (or hard bricks in a pinch) for the
firebox area of the kiln if you are going to try to bring it up to
cone 9 or 10 temps. the K23's will probably deteriorate pretty fast
if the flame is impinging on them directly as happens a lot in down
draught kilns with forced air burners coming in from the side. I
suspect if you are doing something with burners in the floor you will
have better luck with the low temp bricks around the burners.
