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
Nanophase ceramic separation are used to create nanophase ceramics. Synthesizing nanophase ceramics from atomic or molecular precursors are desired more because a greater control over microscopic aspects of the nanophase ceramic can occur. Gas condensation is one way nanophase ceramics are produced. First, precursor ceramics are evaporated from sources within a gas-condensation chamber. Then the ceramics are condensed in a gas (dependent on the material being synthesized) and transported via convection to a liquid-nitrogen filled cold finger. Next, the ceramic powders are scraped off the cold finger and collect in a funnel below the cold finger. The ceramic powders then become consolidated
