Definition
Meaning
A historical/archaic term for the mineral magnetite, an iron ore.
A now-obsolete, picturesque name for the mineral magnetite, primarily used in geological and mining contexts of the 18th–19th centuries, referring to its shiny, metallic luster.
Linguistics
Semantic Notes
The term is a compound noun where 'glance' refers to the mineral's lustrous appearance (from the German 'Glas', relating to shine or luster, as in 'silver glance'). It is a classic example of a now-defunct mineralogical name.
