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.
