熯

The application of heat to transform the state of an object, specifically the process of firing, baking, or hardening. This most typically occurs in the context of ceramics, pottery, or metallurgy, describing the transition from a malleable or damp state to a permanent, hardened one.

Can function as a transitive verb (to fire/harden an object by heat) or as a resultative/attributive descriptor for an object that has been baked or fire-hardened.

The rarity of this glyph usually signals a technical process. If the immediate context does not involve pottery, metallurgy, or heat treatment, consider whether it is being used as a specialized technical term or if it may be a scribal error/phonetic substitute for a more common character with a similar phonetic component.
