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
Compaction of ceramic powders depending on whether the starting materials involve a gas, a liquid or a solid. Examples of methods involving gases are: chemical vapour deposition, directed metal oxidation and reaction bonding, whereas examples of methods involving liquids are: sol-gel process and polymer pyrolysis. Methods involving solids, and especially powder methods, dominate ceramic forming and are extensively used in the industry. The practical realization of ceramic products by powder methods requires the following steps: ceramic powder production, powder treatment, handling and processing, cold forming, sintering and evaluation of the performance of the final product. Since this process permits an efficient production of parts
