If I am understanding the concept correctly you build a fire, let it die down, remove the coals, ash, etc, then add whatever you are baking?

Do you have plans available for this?

Have you tried cooking a pizza in the front chamber while there is a fire in the rear chamber?

I think the front chamber is just an exit for the chimney blocked by the bigger vented door.

After the oven is up to temperature, then the coals and ashes are raked out and the smaller door is inserted farther in blocking off the chimney opening, so just roughly a six inch difference in door placement. 

I have a clay oven on my porch I used to cook in a bit but since it was under a roof it was necessary to put a chimney out the back - the chimney allows a draft so it cools too fast.  The above design eliminates that problem and allows a fast hot fire to eliminate the problems with mine - but it is still cool....

Thanks Glenn! I may attempt to build one of these once my cabin is done. Come in real handy in the summer and keep the heat out of the house.

They use the original smokey ones in Mexico - heat them then cook delicious bread in them.  

The kids used to take me around the pueblo to meet their relatives while the doctors worked the clinic.  I was a pilot to get them there.  We landed on the dirt runway when it was not too muddy, dodging cows, horses and people as necessary.  [ouch]

Here is a link to the clinic at the south end of the runway.   Irma's mom's clay oven is near the corner directly south of the runway, and her place is on the edge of the old dry gold tailing pond by the side of the river- with what in it?  Now the kids play all around there.

Irma's mom said Irma refused to work on the Saturdays when I came to town but she gave me a bit of bread anyway.  Irma was supposed deliver bread around the pueblo.  I had about thirty regulars who entertained me but up to 600 or so showed up one month.  I had to quit bringing them candy, etc.

A little freckle faced 12 year old named Lupita was the boss and put in the orders for the contraband from the states when she needed something.  One month I had to buy all of the used roller skates from all of the thrift stores in Fresno and smuggle them in..... [waiting]

Nice pic, Glenn. ...Wish I was that photogenic..  :-\

It looks like your oven door is made of cob.. I'm surprised it would be strong enough.

We made a simple little (uncreative) cob oven as a test a few years ago..


I really want to try making one of these improved ovens, perhaps with an ash chamber below the oven and a trap door in the back, so that we wouldn't have to pull the coals out until after they've cooled.

Must be the hat because I don't like many pix of myself - this one was not my favorite but was all I could find easily. [ouch]

I also would like an improved oven but the cat has an excuse.  I put it there because there is about a 10000 lb rock under it and it was too much trouble to move.  The oven is functional but not ideal.  The door is cob and weighs about 40 lbs.  Not too practical either.  We seldom use it but it is a good conversation piece and was a good venture into the field of clay oven building.
