Sam,
Take a small sample of each kind of brick and fire it to cone 10. That

Hi Sam
Get a water saw cut a chunk off and test fire it to say cone 6 or 10, put a
test plate under it in case it melts down.There are many bricks available
and too many variables to say what is and what is not test a strip and
conclude your results :)
