Firebricks are expensive, so I wonder about alternatives. I can get "extreme-temperature cement" and use it to cover an oven floor of regular bricks for a slim fraction of the cost of firebricks. Is this any good?
I've also found a "refractory sealing compound" that's made to "renew the high-temperature resistance and performance of worn firebrick." So, if I've got 3-6 inches of sand, then regular bricks, then the extreme-temperature cement, then the refractory sealing compound, would that not be a suitable oven floor?
Basically, what's the cheap and effective way around spending $250 on firebricks?
Thanks!
