fire brick oven heating issue

[segalano]

Hi , I recently made a brick oven with a gas burner it works fine but if I try to increase the heat above 150 degree Centigrade it starts to rattle and feels like its going to crack open . Can any one suggest whats wrong ?

I think the lack of replies to your questions is primarily because everyone here is working with wood fired ovens. The entire design of a construction of these Pompeii style ovens surrounds wood fired cooking. Unless you built the dome to the correct specs, a number of problems can be occuring that would cause it to "crack open". Do you have any pictures of your build? Or explaination of what kind of materials you used?
