I agree with James. I see posts about replacing bricks in the floor of the oven if they crack. I can't see any reason for this. They still absorb and hold heat as though they were whole. Replacing them for a new unbroken brick seems lake a waste of time.

Same same for a dome. I can see wanting to fix the stucco, but I think all and all, the cracks will have very little effect on the ability of the oven to cook food, which is what we are building them for.

That's my guess.
