From Pathfinder Wiki
There are two types of cones:
- a) Small cones that are used in manual kilns. They are placed between a device called a kiln sitter, when they have melted or deformed the kiln shuts off.
- b) Large cones also known as witness cones are used in automatic computerized kilns. As the kiln is automatic they are used to check how the kiln has fired once opened, signalling any problems.
