Historical Definition
Calcitis is a stone from which brass is boiled.
Meaning
The definition identifies its stone through a process and resulting metal rather than by colour or shape. The historical verb “boiled” should remain visible because it is the account’s description of the working. It does not, by itself, establish a complete smelting procedure or a modern mineral species.
A reader should distinguish Calcitis, the starting stone in this sentence, from the brass said to be obtained from it. That simple source/product distinction prevents a lexical gloss from being mistaken for an equation between ore and finished metal.
