Long cracks in my dome

[brickie in oz]

As a bricklayer you get to see lots of cracks, I keep telling the guys to pull theirs shorts up to save my eyes, but they just tell me not to look....

I have to say. My oven has cracks on the outside stucco, one on the arch, and some very fine ones inside the dome. I'm a perfectionist at heart, and at first they annoyed me. The simple fact is, there is just no way we can expect to expose these area to the temperatures we reach, and expect no failures. Do what I have done....enjoy your oven! I think if you don't have cracks, you have not used it enough.

Don't think you can get away without having cracks. They are expansion cracks and will open and close. We were so careful seasoning our oven but after lots of cooking we developed several in the joints. One crack is in a small part of the brick but that could be a brick that had a void in it. We are going to point a few up this Spring and re-season. Would make a few small fires regardless because it has been a long cold winter. Keep on cooking and enjoying. Think if it as a Ferrari....they love to be driven.
Enjoy,
Guy

This oven has a nasty crack!

Looks like it stops right there. As long as it still cooks and doesn't get any bigger you should be fine. The keystone will keep it in place I would imagine.

Too bad, it's in the worst possible place esthetically. Unfortunately, that area of the oven has the highest stresses of any part of the oven. It shouldn't affect the performance. Are you going to try to fix it?
