    Cracks happen. We have seen far worse, I think you will be fine.

      I've got a crack in my dome that is a bit larger than that. I will put some hi-temp caulk on it someday. It doesn't affect performance.

            As I said Dave, cracks happen. There really isn't much you can do about it and I don't think it will be a problem. I have seen one oven that had a 5/8 inch crack - that is huge! He was still able to enjoy his oven and it didn't come crashing down.

                dsm,

                That one looks about like mine, though mine cuts through a few bricks (doesn't stay in the joints). I have found that it expands a bit when hot, then closes up to just larger that yours when cool. I wouldn't worry about it. If it will make you sleep better, try and seal it, and when you figure out how to get grout or hi-temp caulk into that tiny crack, please let me know

                  I would only worry about it if bricks start to fall out onto your pizza

                    No worries, I have a crack just like it! Your oven created it's own expansion joint exactly where it needed one. The oven will continue to use this same crack each time it's fired to expand and contract. Do NOT fix it. Chances are it's the last one you'll get.

                    Your work looks great! Time for pizza.

                        Thought of something could it be that I hit the temp in the oven to high to soon would that have anything to do with it? Is it normal to pile a lot of wood when starting the oven up?

                          Once your oven is cured it really shouldn't matter. It's not like you can go from 0 to 1000 degree's in a second. Your bricks needed to find their happy place - the crack shows you where that is.

                            Nope. Every oven cracks. You built a solid structure that WILL expand and contract with heating and cooling. As Les said, your oven found it's happy place.

                            I promise, in a few months you won't even notice the crack.
