Historical definition

Folia daure are leaves of gold.

Meaning

The definition identifies a form of gold without stating a preparation or further property. “Leaves” should remain visible because it distinguishes the description from a bare metal synonym.

Use in the book

Aurum planatum is leaf gold or malleated gold, and Orizeum foliatum is also glossed as leaf gold. These parallels make the naming relationship useful for searching across authors. They do not supply a particular thickness or manufacture under Folia daure itself.
