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.

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.

Horno at Taos Pueblo is possibly the oldest continually inhabited community in the USA. 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. shimercrazytrip.blogspot
