Thanks, I think I will go ahead and put the floor bricks on edge.

I may start tomorrow if this guy will let me....

No offense, but I wouldn't do it. My main efforts with my oven are other than pizza and I did as much reading of old and new posts on this forum as I could stand. Every variation (almost) has been tried and tested. The heat originates (after the fire) from the dome. If you want more residual heat add more mass to the dome. I used about 1.75" of homebrew refractory mortar to the outside of the dome. The added mass makes heatup longer from what I understand but I can't say how much because I only built one.
On the 3rd day my oven is above 300F. The bottom and top of the bread are evenly done.

Have fun with your build!

Mark

Thanks Mark. You may have convinced me but it is too late!!! It was a pain cutting the bricks on edge and I am not in the mood to do it over again. Hopefully it will work out ok.

SPQR. With my wife being from Rome, I am hoping to attract the spirits and gods for inspiration/protection.
