Which term describes a thermally insulated chamber used for high-temperature processes such as hardening or drying?

Explanation:
A kiln is a thermally insulated chamber designed to heat materials to high temperatures for processes like hardening or drying. The term that best fits the description among the options is kiln seasoning, because it specifically describes using a kiln to dry or season timber, coupling the equipment with the intended high-temperature operation. The other options don’t relate to heat-treatment equipment: knitting and lacemaking are textile crafts, and kiln drying refers to the process of drying in a kiln but doesn’t name the combined concept of the chamber plus its use as clearly as kiln seasoning.
