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 capacitor as precision oscillators and timers. On the other hand, for general applications such as non-critical filtering or coupling circuits, for class 2 capacitors the tolerance series E12 down to E3 are sufficient. Capacitance of ceramic capacitors varies with temperature. The different dielectrics of the many capacitor types show great differences in temperature dependence. The temperature coefficient is expressed in parts per million (ppm) per degree Celsius for class 1 ceramic capacitors or in percent (%) over the total temperature range for class 2 capacitors. Most discrete capacitor types have greater or smaller capacitance changes with increasing frequencies. The dielectric strength
