Arsenic blende or Arsenblende (German: Arsenblende, arsenik-blende) is a trivial name that has partially fallen out of scientific use, used by mineralogists, as well as representatives of mining and craft professions in relation to at least two similar ore minerals — orpiment and realgar, [1]: 135, 239, 438 in composition — arsenic sulfides.
