I'm looking for the optimal hearth firebrick or slab material for high heat pizza baking.
At 900F+, Fibrament (thermal conductivity of ~0.8 W/mK) burns the bottoms before the top is done. K23 insulating firebrick (thermal conductivity of ~0.2 W/mK) leaves the bottoms underdone, and also is dusty and crumbly.
I haven't tested them, but standard duty firebricks all have thermal conductivity >1 so it would seem they would also burn bottoms at 900F+.
I believe I need a food safe material between 0.2 and 0.8 W/mK that could handle abrasion from a pizza peel.
Terra cotta is one potential material with thermal conductivity in that range. I was also wondering if the higher density insulating firebricks like K32 at ~0.5 W/mK would work.
