Just got my hands on some used hard brick. Horror stories abound locally
about Canadian fire brick failures at cone 10R and my local (helpful)
masonry supplier cannot find specs for some of the brick.Can anyone help
with:
1) C 1 0 6
1-XL
Canada

2) CANADA
FLAME

I ALSO HAVE "AMERICAN XX" AND "IDAHO" BRICKS. Any suggestions on which
bricks hold up better as posts/kiln furniture? Veronmica

The easiest and best thing to do is to make a test. Break a small portion
of the brick. Isolate it so that it melts on no other pieces. Perhaps place
it in some saggar or similar. Fire away! If it is still in the same
shape/form when you open the kiln, it should stand the test. Test at one or
two cones above and one or two cones below the desired cone limit.
