Hey all,

I built a form for my insulating layer which should closely match my oven floor.

The forms allow for about four and a half inches of perlcrete.

But I have decided to pour three and a half inches of perlcrete followed by about an inch of high temp mortar.

This should make for a very smooth and level surface to lay my bricks.

And it will add a bit of thermal mass to the oven floor, which should be beneficial.

Opinions?

I've included a picture of the forms and part of the perlcrete pour.
