It is also used in etching iron, in removing iron scale from forgings, in petroleum refining, etc., and in general its manufacture is the most important and fundamental of all the chemical industries. Formerly called vitriolic acid, and now popularly vitriol, and oil of vitriol. Fuming sulphuric acid, or Nordhausen sulphuric acid. See Disulphuric acid, under Disulphuric.
