I found a local fire brick supplier for $1.05/brick. Composition is as follows:
66.9% SiO2, 25.6% Al2O3, 2.5% Fe2O3, 2.6% alkali, 1.5% TiO2, etc. Recommended max operating temp is 2000 deg F.
Does this look like the right stuff? I assuming SiO2 is silica of some sort and Al2O3 is Alumina of some sort but I really didn't pay too much attention in chemistry (it was an 8:00 am class)
