Historical Definition
Calx Solis is calcined gold.
Meaning
The definition gives a familiar material in a prepared condition. The planetary form of the name is decoded explicitly as gold; the action is calcination. A reader should preserve that preparation rather than replace the complete expression with unqualified gold.
Compare Aurum planatum, a worked leaf form, and Aurum vitæ, which is described through precipitation, reverberation and redness. The shared gold vocabulary does not make those products interchangeable. The dictionary supplies separate entries because form and treatment can be central to the intended sense.
Places to Read

Aurum planatum. Gold identified by being beaten into a thin form.
