Outdoor Ovens with Earthen Veneers

Examples of pure cob and adobe, and refractory castable cement over bricks.

There are two common ways of building cob ovens: one is to make a mold of sand, upon which the oven is built, and after which the sand is removed through the oven door. The other is the Quebec-style oven, in which the form is built of saplings bent into a hemispherical shape, upon which the oven is built, and after which the saplings are burned out in the first fire. Another less green option, castable refactory cement, can withstand temps to 2200º F.

horno

Hornos are traditional pueblo, beehive shaped, adobe ovens. Used mostly for baking and roasting, other cooking can take place at the opening while the horno is being fired. A fire is built inside allowing the thick adobe chamber to absorb heat. After two or three hours coals are removed to a nearby brazier for other use or to reheat the oven as needed. Whatever is to be baked or roasted is placed in the oven and the smoke hole and doorway sealed. An horno can maintain a useable, though slowly dropping, temperature for several hours.

Many adobe walls, domes and vaults are made of individual sun-dried mud bricks, bonded together with mud mortar. Cob construction is hand formed by shaping thick layers of mud directly on the wall or object.

wood fired outdoor oven

Start the fire in the front - shift further back once established. When roaring, push it to the back, so the roof of the chamber heats evenly.

Hi Laurie,
Sounds a fun project. As to the marble, I personally do not know anyone who used marble as a cook surface in an outdoor oven. But all kinds of questions arise as to the idea: how thick is the marble? Are there extreme temperature changes in your area? Will there be stress on the edges from the upper part of the oven? I have googled the idea and see people use marble as bread cooking stones...but see no use as a base...sorry I could not be of more help!

marble slab
Reply #2 on : Tue June 04, 2013, 00:07:25
I am building an adobe oven and I was wondering if I could use marble slab for the floor of the oven as the cook surface. I am putting the slab on top of firebrick. Have you heard of this being done

One of the keys is complete combustion...
