Kiln

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. Various industries use rotary kilns for pyroprocessing to calcinate ores, limestone to lime for cement, and to transform many other materials.
Building instructions
Making an improvised furnace can be as simple as digging a small pit unto the ground, cutting a small groove into the edge to allow air from a set of leather bag bellows and placing a turf cap over the pit.[1]
Temperature
Normally, a natural draft furnace using wood, a kiln, can reach up to 1400 Celsius degrees (or 2552 Fahrenheit), while a furnace that uses fuel such as charcoal can reach temperatures up to 1600 °C (2912 °F) degrees.[2][3]
