Hairline Crack

[Gianluigi]

I finished building my oven last June and by the 3rd time using the oven I noticed some crack inside the dome in 2 different areas. I am wondering if i should leave it the way its or should re-patch them. Any advice?

Thats nothing to worry about, my cracks are much larger than that. YOu have nothing to be worry about.

What did you use to seal the dome? I notice some type of pain over the stocco. I need to do that but never got around it.

Hello, thank you for the advice, I will patch them anyway with home brew mix if I can fit inside? I gained some weight since the oven was built. Regarding the outside I used 2 coats of stucco and 2 thin coats of Venetian plaster stucco in terra cotta color then I sealed the outside with seal krete.

Gianluigi, that's a nice looking oven and stand. From what I could pick up after reading this forum for the last couple of years, a few small cracks are normal. Those look very minor. I just about done with my curing fires and have a small hairline crack. I think that the concern re cracks is large ones (1/8" or larger...) that can let a lot of heat and steam out of the oven.

Gastagg, I am sorry I was just able to read your comments! Thank you for your comments about the build, As time goes by I feel less worry about the crack.
