Great question…and the answer is still up in the air. We were considering a cast type dome and I have been looking at recipes on this.
I found the below link… https://www.traditionaloven.com/tutorials/concrete.html

UPDATE:
I spoke with Dave, my friend first and expert mason second, and we both agree that using the cast refractory cement is the way to go for this project. I saw that this site, brickwoodovens.com, states that a homemade recipe will certainly fail and it says to buy a pre-mixed solution.
Thoughts on that, especially after seeing the previously mentioned recipe I found?
