Kiln

A kiln (originally pronounced “kill,” with the “n” silent, however vocalizing the “n” has become popular.) is a thermally insulated chamber, a type of oven, that produces temperatures sufficient to complete some process, such as hardening, drying, or chemical changes. Various industries and trades use kilns to harden objects made from clay into pottery, tiles and bricks. Various industries use rotary kilns for pyroprocessing—to calcinate ores, produce cement, lime, and many other materials.
