Rare. In the text, Mentzel compares the luminescence properties of the naturally occurring Bologna Stone (phosphorescent barite) and a newly discovered preparation called Baldewinian Phosphor. He notes that the compound more easily absorbs light and emits at a stronger intensity than the natural stone. However, the theoretical reasons behind these observations are disguised in the language of alchemy with no rational reason provided.

Gatterer says this work was reprinted in Ephem. Nat. Curios., 1 (1676), 158 ff.
