  Think it is out of print, but check Amazon- Professional Care and Finishing of Gun Metal. Covers rust blue, caustic blue, and hot water (nitre) bluing- including making your own. But you will not find "Spirits of Nitre" at a drugstore anymore.

  Turn parts and small pieces a deep, rich, lustrous blue with a finish that's tougher and prettier than most of the cold blues. The process is really quite simple: Heat the salts up to 570? F. - 650? F. (they are NOT dissolved in water, they're used straight). Dip the parts in, watch for the color change. Lower temperatures give a "straw" color like the older Luger parts. As an added bonus, the salts can be used for the drawing operation when heat-treating springs and parts.
  
  SPECS: 10 lb. (4.6kg) or 20 lb. (9.1kg) in plastic, resealable plastic pail. 1 lb. of salts will take up approximately 15 cubic in. (245 cubic cm).
