NITRE BLUING PROCESS:

MATERIALS:
1.Steel or Iron container
2.Sodium Nitrate or Potassium Nitrate
3.Transparent Lacquer Spray or double boiled Linseed Oil

Process:
Prep your parts by polishing them with steel wool,sandpaper or buffing wheel etc.After polishing degrease them using good quality degreaser or you can use ACETONE or mineral spirits.Tie your degreased parts with wire and don't touch with your fingers because the finger prints will show on the finish.
Now put your steel container and put it on a stove and start heating it when its hot enough start adding the Nitrate salt and check if it starts to melt keep the heat on medium don't boil the salts keep adding the salts stir !!METAL SPOON ONLY!! don't use wood or combustibles because NITRATES are OXIDIZERS and would instantly burn things like wood,rubber,leather,plastics etc.
BE CAREFUL and keep the molten salt bath away from water sources because a single drop of water may cause an eruption in the salt and serious injuries may occur and make sure there is no moisture on the surface or the part it should be totally dry blow them with a hair dryer to ensure complete dryness .
Only use enough heat to keep the salts in a molten state and keep adding extra salts till you reach your desired level.
as soon as all of the salts melt lower your parts in the salt bath and keep them moving in the bath so the air bubbles would escape.
As you dip and move your parts around you will see the colour of the metal change don't keep the part in the bath for long lift them out and dip them again or you will get the part heated up quickly and you would not get the desired colour.Keep dipping and checking the colours change when you reach the desired colour lift your part out and hang them to cool down.
After cooling wash the part with water to remove any salts present and spray a light coat of Transparent Lacquer to protect the finish.
!!!!!!CAUTION!!!!!!
Molten salts are very hot and due to their oxidizing nature the will oxidize and burn any flamable objects and serious burns may occur if not handled properly after use keep the salt bath to cool down and store it in a dry place you can use it again and again.Whenever you want to reuse the salts make sure there is no moisture present if there is any heat the bath really slowly so the moisture gets evaporated before the salts starts melting.
Do not use this process on Springs/Leaf Springs or flexible parts because the heat will alter the TEMPER and make them useless.
Avoid Barrels because the heat can weaken the barrel structure.
Try to practice on scrap steel before you try it on your own firearm parts.
This process
!!!!!!!!!!!!!!WARNING!!!!!!!!!!!!!!
I am not responsible for any kind of injury or damage caused using the process please take precautionary measures when making an attempt.


You can achieve results like these shown in the pics if you do it right this is my personal attempt on an extractor from a P-14 Rifle Bolt.

These are some pics of my personal attempt of NITRE BLUING
the part used is an extractor from a P-14 rifle I did this back in 2010.
I have shared the whole process in my post "Anyone interested in Nitre Bluing" post #5.

Nice info.
I'd just pay 500/rs to a gunsmith and have it done without going through all this procedure and buying chemicals is getting noticed for nothing and a headache these days.

Brother,if you read the whole comment carefully and ignore 500/rs :

1- I appreciated his effort, very good job indeed.
2- I presented an alternative solution which 99% of ppl. will usually do.
3 -I warned against buying chemicals without knowing their use.
4- MashAllah our law enforcement ppl. are not Chemical engineers or do not hold a MSc degree in Chemistry and using chemical names in English will always raise their eyebrows these days.
5- If ppl. can make destructive bombs (like Oklahoma city bombing) with fertilisers then there are many uses of nitrates ,sodium and potassium and how to filter out them from seemingly harmless compounds in evil ways too.
6 - i am a very much DIY guy myself in Auto mobiles and modifying weaponry (for fun use).

BTW this info is available on net if you search.
Before 9/11 there was a whole published document on atomic weaponry and energy with building design and dimensions.The author's ideology was that everybody should have it to prevent greater damage and use of atomic energy should be diverted for electrical purposes but obviously it's taken down now.

Cheers!

My dear our law and enforcement personels know that nothing dangerous can be done wd potassium nitrate or sodium nitrate .for cheap illegal activity only a close kitchen is sufficient.let us learn more if u have already excelled in bluing pls

I dont think its going to work on opinel or inox because they have stainless steel it wont get the layer of oxidation that colours the steel I have tried stainless and it didnt work

Do not nitre blue your knives only do it if you're making your own knives because molten salts can have temps in excess of 700 degrees it will ruin the heat treatment of your blades.

Blueing kay liye hamesha full disassemly karna hota hai kyoun ke kuch parts ko behtar hai ke na karein kyoun ke un ka heat treatment ya temper kharaab ho sakta hai
