My first post and well involved in the pompeii construction.
I have decided to go through with 2" of ceramic board installation over the supporting concrete. My questions is, how much of the ceramic board do you need as surface area, e.g, do you need just a circle under the oven only or do most people make a rectangle or square that is bigger than just the dome? My second question is since you place the ceramic board 2" tall, what is placed around the rest of the remaining supporting base that does not have the ceramic board on top of it. If I was using the vermeculite insulating concrete, the entire surface would be elevated rather just a circle or rectangle.
Thanks in advance,
Charles
