Masonry oven and the fire won't burn well. Modern masonry ovens sometimes bear little resemblance to their forebears, and can have just a cast deck (similar to a pizza stone) inside a more conventional oven exterior. Such devices are primarily used in commercial settings, though tabletop models are available. Cob is the British name for what is essentially adobe (from Arabic, "al toba," meaning "the mud;" "cob" is the Anglo-Saxon word for "lump," and is also used to describe round loaves of bread, or small, compact horses). As the most common building material on the planet, earth, clay and "cob" construction have
Earth structure principal directions, based on wall thickness, story height, bracing wall spacing, and the roof, loft and second story weight above earthen walls. Building techniques that are more ductile than brittle, like the contained earth type of earthbag, or tire walls of earthships, may better avoid collapse than brittle unreinforced earth. Contained gravel base courses may add base isolation potential. Wall containment can be added to techniques like adobe to resist loss of material that leads to collapse. Confined masonry is effective for adobe against quake forces of 0.3 g may be useful with earthen masonry. Many types of reinforcement can
