If they are happy with their oven, that's the important thing.

As far as cracking; any oven built with brick and mortar simply has to crack somewhere. The physics of thermal expansion an contraction guarantee it. Some cracks are big, some are small. But they are there.

Even with this knowledge, we all are a little disappointed after we fire our babies up the first few times and discover the inevitable C-R-A-C-K-S.

I promise... Allen Scott ovens develop cracks as well.

Cracking is a result of uneven thermal tension and discontinuities in the oven structure. Stress concentration occure at all discontinuities in the design and when thermal gradients exist (during heat-up). A dome (spherical shell) will usually have less discontinuities than a barrel oven as the barrel have end walls. The main discontinuities in the Pompei design is around the door opening and the dome/floor interface.
