Ok, been gathering material for my upcoming build and (perhaps stupid) bought 300 unseen fire bricks (far from home) which my relative picked up along with 100 kgs if fire clay.
Everything seemed to be fine, except that the bricks were not really rectangular but instead had a more “slightly triangular” shape going in thickness from 3 to about 2.5 inches. Stacking 2 on top of each other indeed creates a flat surface although the thickness of the brick layer would be 5.5 inch. (I also have about 1 sq metre hand made terracotta plates for the baking floor if I can’t find real biscottis.
My dream/plan is to build a neapolitan oven, but for the floor - stacking 5.5 in of bricks on the vermiculite iso layer feels like a bit to much (unnecessary) thermal mass.
But would that be recommended compared to build the floor with sand/clay and then try to “level” the triangular shaped bricks into a flat surface?
(I read that terracotta plates isolates a bit from the fire bricks but there is a bit of uncertainty here..)
Not sure that I managed to describe my issues here (I am Swedish) but please ask and I’ll try to give a better explanation.
