WORLD CIVILIZATION

Detailed explanation-1: -A kiln is a thermally insulated chamber, a type of oven, that produces temperatures sufficient to complete some process, such as hardening, drying, or chemical changes. Kilns have been used for millennia to turn objects made from clay into pottery, tiles and bricks.

Detailed explanation-2: -A special type of the high temperature kiln is the hot steam kiln. The hot steam kiln will operate above 100°C (Range:102-110°C/215-230°F) but will dry in super heated steam. Hot steam kilns use heavy duty moistening devices (cold water spray and steam spray), to reach the required high humidity for the heatup stage.

Detailed explanation-3: -Kilns are insulated chambers that reach high temperatures using either fuel or electricity. A kiln uses a process invented thousands of years ago to harden ceramic bodies. In ceramics, modern kilns are used to fire clay and porcelain pieces. Think of a kiln similar to that of an oven.

Detailed explanation-4: -What Is Firing? Firing is the process of bringing clay and glazes up to a high temperature. The final aim is to heat the object to the point that the clay and glazes are “mature"-that is, that they have reached their optimal level of melting.

Detailed explanation-5: -Fired clay is either called ‘ceramic’, ‘bisqueware’, or ‘glazeware’. Clay is normally fired twice. After the first firing, the clay is called ‘ceramic’.
