A kiln is a thermally insulated chamber designed to reach and maintain elevated temperatures for the purpose of firing ceramics, sintering powders, or calcining materials. Its parameters are: (1) a combustion chamber or heating element that generates controlled heat; (2) refractory lining that retains thermal energy; (3) a means of temperature regulation (damper, vent, or electronic control); and (4) a load chamber where the workpiece sits. The persistence mechanism is physical construction — built from fired clay, brick, or stone, and sustained by fuel (wood, gas, electricity). Once built, a kiln persists as a durable artifact until destroyed. [formal: clibnum | substrate: matter | horizon: a life | explicit: yes | epoch: 0.01]

Definition
Why it is in scope
A human-made oven constructed for firing ceramics, brick, or other materials at high temperature. Built from refractory materials, it is an artifact of the fired-materials tradition — the controlled application of heat to permanently transform materials through sintering, vitrification, or calcination. A human-made construct, not a geological feature.

Kiln is a specific kind of tool (Law 9): an artifact designed to extend human capacity for high-temperature material transformation. Competent-speaker test: 'a kiln is a tool' is straightforward — it extends thermoregulation capacity to fire materials. No ladder rung exists between kiln and tool that would make this a leap.

Per Law 8d: the kiln is built and maintained for the sake of craft — it is the specialized high-temperature firing tool for ceramic and metalwork craft. Its designed purpose is to serve the craft domain. The servant (kiln) points at the master (craft). Remove craft and the kiln has no purpose.
