Zinkenite
A variety of Minerals
What is Zinkenite?
Zinkenite is a unique and rather uncommon mineral recognizable by its metallic steel-grey needle-like structure. This mineral was discovered in 1826 and is named after the German mineralogist discoverer, Johann Ludwig Carl Zincken. Though zinkenite may look strong, it is actually relatively soft according to the Mohs scale, which is the measurement to determine the hardness of a mineral.
Uses & Applications
Zinkenite is a mineral specimen that is primarily used by collectors. It is also a source ore of lead in some areas, though more common minerals are more important sources. Lead is currently used in some applications such as car batteries, pigments, weights, and some glass.
