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
Ceramic armor These are the motivations for new types of armor plate. These new designs use two and three dimensional arrays of ceramic elements that can be rigid, flexible or semi-flexible. Dragon Skin body armor is one these systems, although it has failed numerous tests performed by the US Army, and has been rejected. European developments in spherical and hexagonal arrays have resulted in products that have some flex and multi-hit performance. The manufacture of array type systems with flex, consistent ballistic performance at edges of ceramic elements is an active area of research. In addition advanced ceramic processing techniques arrays require
