Historical definition
Sal Calcotharinum is salt made from the colcothar of vitriol.
Meaning
The preparation is defined by its relation to a residue called colcothar. The named starting material matters: the entry does not identify the product simply as vitriol or as any salt whatever.
Use in the book
Compare the separate vitriol headwords Vitriolatum and Vitriolum Novum. The dictionary’s qualifiers distinguish a liquid condition, a color designation and a preparation obtained from a particular material.
