At a Glance

The word. A vitriol-derived salt identified through transparency and preparation.

Historical Definition

Citrinulum is a transparent salt made from calcined vitriol.

Meaning

The entry states a sequence: vitriol is calcined, and a transparent salt is made from it. The starting material and the final salt should not be treated as the same state merely because they share a source. Transparency supplies an appearance clue, not a complete composition.

Calcanthum provides a direct route to vitriol vocabulary. Citrinula and Citrinulus are important spelling comparisons, since one names an herb and the other a pale crystal. Reading the final letters carefully prevents a material identification from drifting into the wrong neighbouring entry.

Places to Read

Calcanthum. A historical term identified with vitriol.

Citrinula. A plant name with an attributed blister-producing effect.

Citrinulus. A crystal identified through a pale appearance.
