Southwest Adobe Oven - 1938:  Hornos (pronounced "or no") are traditional pueblo, beehive shaped, adobe ovens.   Unlike large earthenware chimineas, which are movable, hornos are massive and fixed, so, be sure it's where you want it when you start to build.   While they are sometimes referred to as kiva fireplaces, (no one knows why, hornos are outdoor structures never found in kivas) this is a misnomer.   Often benches, braziers, storage, work areas, etc., will be attached to an horno.   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 place in the oven and the smoke hole and doorway sealed.   An horno can maintain a useable, though slowly dropping, temperature for several hours.  This Linen Era postcard, published in 1938, is in good condition.  Genuine Curteich-Chicago.  “C.T.
