Built one before – was very much viewed as an experiment/learning opportunity since it was our first attempt at building anything with cob.
We failed to prepare the foundation well enough, and also placed th oven too close to wet ground. After using the oven very successfully a number of times, we had some very heavy rains which cause the base to shift – clay swells when wet – which cracked the lime-plaster. Water got into the underlying cob and the oven began its journey back into the Earth it came from…
Its been a couple of years now, but we haven’t got around to building a new oven. I miss it, though.
