Historical Definition
Calx Martis is crocus of steel or iron.
Meaning
The historical definition offers steel and iron as the material family and crocus as the prepared identifying term. It does not state a single procedure or modern composition. Preserve both material alternatives, rather than choosing one merely because a later recipe is more familiar.
The neighbouring Calx compounds show why the complete name matters. Each has its own gloss, and their products should not be collapsed into one generic ash. A passage describing the preparation, colour or treatment of iron can clarify the particular crocus intended.
