Historical definition

Fuligo Metallorum is sometimes called arsenic, and sometimes means Mercury.

Meaning

The entry records two uses rather than one fixed identification. The repeated “sometimes” leaves their circumstances open. A surrounding author’s material and operation must determine which meaning is plausible.

Use in the book

Arsaneck is sublimed arsenic, while Guma is directly identified as Quicksilver. These comparisons distinguish a prepared condition from a simple material name. Neither settles which of Fuligo Metallorum’s two alternatives a particular author intends; that decision needs evidence from the passage being read.
