Masonry oven the benefits of a masonry oven without constructing a full oven. The most common method is the stoneware pizza stone, which stores heat while the oven is preheating and transmits it directly to the bottom of the pizza. Common firebricks can be used in a similar manner to cover a shelf. Bread and meat can be cooked in a type of covered ceramic casserole dish known variously as a cloche, a Schlemmertopf (brand name), or the like. Good results can also be had by cooking the bread in a pre-heated Dutch oven with a well-fitting lid. Most expensive is a
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
