Cement v. firebrick hearth
In the book The Bread Ovens of Quebec, in the case study chapter, the oven builder indicates that "thirty-five years ago [he] used bricks to make the hearth, but now, [he] uses cement."
I may build a sort of hybrid oven - Quebec-style "half pear" shaped mud oven, firebrick (or cement?) hearth, and concrete block or recovered stones for the foundation walls.
Cement for a WFO floor, even if it's refractory, in lieu of bricks? Anyone have thoughts on this?
