Webster's Dictionary (1913)
Blende (…), noun
Origin: G., fr. blenden to blind, dazzle, deceive, fr. blind blind. So called either in allusion to its dazzling luster; or (Dana) because, though often resembling galena, it yields no lead. Cf. Sphalerite.
Mineralogy (a) A mineral, called also sphalerite, and by miners mock lead, false galena, and black-jack. It is a zinc sulphide, but often contains some iron. Its color is usually yellow, brown, or black, and its luster resinous. (b) A general term for some minerals, chiefly metallic sulphides which have a somewhat brilliant but nonmetallic luster.
