Historical Definition
Cathimia is the scum of silver.
Meaning
The word identifies a portion or product associated with silver, rather than simply the metal in every state. “Scum” gives its relation to a separation or working, but the entry does not explain which process produces it. A reader should look for that operation in the surrounding source.
Calx Luna gives a different silver preparation, the azure flower. The two should remain distinct unless a cited passage explicitly connects them. Shared origin in silver is not by itself proof of identical material.
Places to Read
Calx Luna. A silver preparation characterized through blue colour and flower vocabulary.
Luna. The lunar name denotes silver.
Scuma. A name referred to squama or scale.
