Tips

usage
Mostly a traditional-medicine and chemistry term: 煅 is one of the standard ways to process minerals and shells, heating them fiercely in fire to change their properties. It is a fire-radical variant of 锻 (to forge metal).

Components

radical
火 huǒ
fire
The fire radical on the left, the meaning carrier. Calcining is done by intense heat, so fire supplies the core sense.
phonetic
段 duàn
section; to forge
Provides the sound, read 段 and unchanged here. It is the same phonetic that appears in 锻 (to forge), a closely related fire-and-metal idea.
