Historical Definition
Callena is a kind of saltpetre.
Meaning
The expression “a kind” gives a class but no distinguishing properties. The entry therefore directs the reader toward saltpetre vocabulary without determining a source or a prepared form. A passage’s description must supply the difference that makes its Callena a particular kind.
Nitrum and Sal petre provide related entries. Their connection helps readers navigate historical names, but it should not become a claim that every named saltpetre in every text was a chemically standardized material.
Places to Read
Nitrum. A name for saltpetre.
Sal petre. A salt described through cold air and growth on stone.
