Tag man_made=kiln is used for mapping a kiln - a thermally insulated chamber in which temperature is controlled to change the state of the item placed inside, usually through the process of burning, baking, drying, or smelting.
Kilns are used to turn objects made from clay into pottery, tiles, and bricks, and to turn wood into charcoal. Various industries use rotary kilns to calcinate limestone to lime for cement and to transform many other materials.
How to map
Set a node or draw as an area along outline and add man_made=kiln
The product produced in the kiln can be described with product=*:
If the kiln is large it may have man_made=chimney features, and it may be within a man_made=works (factory) and landuse=industrial area.

Bottle kilns (also known as bottle ovens) were widely used in the pottery industry and some still survive (notably in Stoke-on-Trent), though they are no longer used in the UK, where they are listed historical buildings. They should be drawn as an area along the outline, and tagged:
Bottle kilns in the UK are likely to be listed buildings, in which case the following tags should be added:
- listed_status=Grade I, Grade II*, or Grade II
