blende etymology

Etymology of "Blende"

The word "blende" has roots in German and Swedish.

  • German: "blende," meaning "to blind" or "to dazzle"
  • Swedish: "bländning," meaning "dazzle" or "deception"

Meaning and Origin

"Blende" originally referred to a mineral that had a metallic luster but was not a true metal. This included minerals such as pyrite (fool's gold) and sphalerite (zinc blende). It gained this name because it often "blinded" or fooled miners into thinking it was a valuable metal.

Over time, the term "blende" has come to refer to any mineral with a metallic luster but is not a metal itself. These minerals typically have a high percentage of sulfur or selenium. Examples include:

  • Sphalerite (zinc blende): A mineral composed primarily of zinc sulfide (ZnS)
  • Galena (lead blende): A mineral composed primarily of lead sulfide (PbS)
  • Chalcopyrite (copper pyrites): A mineral composed of copper, iron, and sulfur (CuFeS₂)
  • Pyrite (fool's gold): A mineral composed primarily of iron sulfide (FeS₂)

Today, the term "blende" is mainly used in mineralogy to describe these types of minerals. It is also occasionally used to refer to other substances with a metallic luster, such as metallic paints or coatings.
