Way to go Nick, nice to hear from you.

Calpollyalli -- can you post something about the bee die-off in the Chit-Chat Section (otherwise known as how are we going to feed outselves without pollination). I'm a big fan of olive trees, and they have small little white flowers that have to be pollinated by insects -- I'd like to learn more.

Hmmmm, out of curiosity, does anyone know how the exterior of the oven (made of cob) is insulated? If it isn't, how hot does it get?

Yes I'm resurrecting an ancient thread. So sue me...

I think I figured out how to do it. I saw a picture of an oven that had been made on a wooden stand - it was portable if I recall correctly - and that gave me an idea. Cob houses sometimes incorporate wooden beams in order to support the weight of the roof. It seems to me that I can do the same thing to support the weight of the oven. Rebar and concrete would form the actual table top (for want of a better term) cob would form the walls and encase the wooden beams.

Hi Archena,
We are hoping to use mudbricks for our stand. These are as strong as block bricks and with a sealant like boncrete, they will last forever.

Re: Question: Has Anyone Ever Used Cob for the Stand?

I have been very involved and have helped build mudbrick houses, and I know the strength of a good mudbrick,( as long as they are made right in the first place) .
I have no doubt the ones we are going to be using will do the job just fine.
Just to add to your confusion ..lol

I once built a pottery kiln out of mud bricks in Carisbrook, Vic. It worked ok. We got it so hot, around 1100 C I would estimate and the inside sheared off in melted sheets from the high iron content in the clay, but the pottery was not affected. Mud is a great insulator. At our temps (450 C max) it's refractory enough.

Re: Question: Has Anyone Ever Used Cob for the Stand?

Actually mudbrick doesn't confuse me all. I've done a good bit of reading about it as a result of all reading I've done about cob.

I'm sure everyone here will be surprised that there's anything that doesn't confuse me...

The very first ovens in history are just basically cob.
