Some formulations include the use of nitrates and nitrites (sodium or potassium), thus "nitriting". The temperature differences depend on the chemical formulation, finish desired, etc. True blueing normally involves extremely high temperatures (300 degrees F), is very dangerous, and should only be done by experienced professionals.
