Maximum dome height of cob oven

Hi,
Has anybody had any experience building a large cob oven?

I'm not sure how to define 'large' - perhaps 'large enough to bake 3 large pizzas at once'.

I'm asking because most of the of the ovens I've seen on the web are roughly the same size.

I have not seen anything with a big baking surface.

I've only worked with the regular size ones.
This one looks larger...info about it is on small-scale.net
I can smell those pizzas already!
All the best

Thanks Kate. That is exactly what I was looking for.

I had been to that site but had not found those pictures.

Aside from the large oven, the pictures show a way around building a large based for a large oven - lower the baker instead of raising the oven.

nc dirt farmer - did you end up building a large cob oven? A friend of mine who is a baker was looking for designs for an oven for three+ pizzas or 10+ loaves of bread, and I was just wondering how your experience with building this was, or if you came across any other good resources for large designs. Thanks!

I built a LARGE one. It will hold a full-size commercial sheet pan or 3 normal home-sized sheet pans or 3 16 inch pizzas.

The dome is a little taller than normal, but not that much. As long as you keep the door height/dome height ratio right it will draft just fine.

It is a LOT more cob (and work) to build than a normal size. And the base was a HUGE job--I did a rammed earth base and it was enough material to do a whole cabin wall!

Thanks for the info R Scott. This particular project fell through, but I'll be helping out on a moderate-sized cob oven this summer, as well as probably tinkering with building a barrel oven in the fall.

Kiko Denzer has done quite a bit of work with cob ovens, including a mammoth commercial piece. My iPad does not want me to copy and paste links, or I would ofer the link to Kiko's blog. A quick google for his name will produce lots of good cob oven related material. His book was my gateway into making them
