Hi, I may want to change the design of the base ever so slightly. Are the split (half thick) firebricks ok to use instead of the full thickness bricks? This is for the cooking surface only. i do not want to have any heat issues when cooking the pizza.
I am trying to keep my height down on the cooking surface and hearth for a certain design (aesthetic) look that i am going for so essential the top surface of the hearth can be sanded down with exposed stone and glass pieces etc, whereas the design shows to add brick on top of the hearth. Or can I increase the insulating layer (vermiculite/portland cement) from 2 inch to 3 inch to make up any differences. this is still a 5inch hearth slab. thanks.
