Nitre is an obsolete name foe some nitrates. Nitreis a word derived from the Greek language nitron (a term used in the past for sodium carbonate or the potassium nitrate). But also nitron is very probably borrowed from the old Egyptian netjeri.
The approximate operating temperature for bluing with nitre- blue salt is around 290-310°C (550-590°F). At this temperature, the parts are immersed in a bath of the nitre-blue salt for a specific period to achieve the desired bluing effect.
A method of separation may be the fractional crystallization.
Nitre beds have been used for years to make potassium nitrate, they consist of manure, ash and urine. They stacked the "ingredients" on a bed of clay then left it till it formed a white crust, this was then removed and washed with water, this got rid of the other soluble products. They used then potassium nitrate to make gunpowder.
Nitrogen gets its name from "Niter" (Potassium Nitrate, KNO3) + Latin. gènere,You can use Potassium Nitrate to prepare Nitrogen.From Latin nitrogenium or French nitrogène.Nitrogen had been elementally found in nitric acid, which in turn is formed from saltpetre (potassium nitrate), in Lavoisier's time known as 'nitre'.However, this word in the more ancient world, originally described sodium (Na, Latin 'natron') salts that did not contain nitrate, and so the word is a cognate of natronand nitron.The last part, gènere , means "producing" (from Gk. -γενής means "forming" or "giving birth to" compare 'genisis').
Nitre, also known as potassium nitrate, is a compound composed of potassium, nitrogen, and oxygen. It is not an element mixture, as it has a fixed chemical composition with a specific ratio of atoms.

In Edgar Allan Poe's "The Cask of Amontillado", Montresor refers to "nitre". Nitre is mineraled potassium nitrate that grows in damp places. As Monstresor leads Fortunato down to the wall vault where he will meet his fate, the walls are covered with nitre.
Immortal Night and Nitre. http://www.immortalnight.com http://www.nitre.webs.com But Nitre isn't finished yet. Nitre is a downloadable werewolf game and it is not finished. Immortal Night lets you choose between a Vampire and a werewolf, and it is online. Immortal Night needs Internet, but Nitre doesn't. Here is how they are pronounced: Immortal Night (Imm or toll ni t) Nitre (Ni tree)

Gunpowder is a mixture of nitre (potassium nitrate) , sulpher and charcoal Name of the method- filteration , evaporation and solvent extraction. Steps- 1) Put the constituents in water. nitre will dissolve in water. 2) Filter the soln. Filterate- water+nitre Residue - sulpher+charcoal 3) Perform evaporation on the filterate. Water will evaporate leaving nitre. Solvent extraction- 4) Put the residue in carbon disulphide. Sulpher will dissolve in this soln. 5) Filter the soln. Filterate-carbon disulphide+sulpher Residue- charcoal 6) Perform evapooration on the filterate. carbon disulphide evaporates leaving sulpher.

The approximate temperature for bluing with nitre blue salts is around 600-700°F (315-370°C). It is important to closely monitor the temperature during the bluing process to achieve the desired finish and avoid overheating the metal.
