Gorgeous "Fire Blue" Colors & No-Scale Tempering - A Master Metal Finisher's Secret Useable In Any Shop
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.
