If coming from out of country I would make sure it's asbestos free as some places in the U.S. had high concentrations & can no longer be used, I sure wouldn't try cutting anything like that without a wet saw & mask.
Thanks, samhill. From that and from other stuff I'm reading, I'm just going to pay a bit more and get regular firebricks for my stove.
