Name of Wolframite

The name "wolframite" is derived from German "wolf rahm" ("wolf cream"), the name given to tungsten by Johan Gottschalk Wallerius in 1747. This, in turn, derives from "Lupi spuma", the name Georg Agricola used for the element in 1546, which translates into English as "wolf's froth" or "cream" (the etymology is not entirely certain), and is a reference to the large amounts of tin consumed by the mineral during its extraction. Wolfram is the basis for the chemical symbol W for tungsten as a chemical element.
