Where do you get Salt Peter (potassium nitrate)???? Answered

Does any body know where to get Salt Peter (potassium nitrate) but not from uni's or from the internet?? If not how do u make it?


It's not difficult to get Salt Peter at all. It can be purchased at your local pharmacy, but they sometimes ask too many questions. Visit your local Farm Supply, or feed store. Salt Peter is used by folks who breed horses, but want to control the lust amongst their stallions. You can buy it in 5 -10 lob bags much cheaper than you can purchase it at pharmacies.

I have made Black Powder. It's perfectly legal. A friend built a "mortar" that will hurl a fourteen pound bowling ball two miles, using Black Powder. We'll soon go for three miles! I think he would do well in competition.

It's perfectly legal, provided you are building a cannon/mortar that is muzzle loaded, has no breach loading capability, and uses Black powder. I bought a five pound bag of Sulphur today. The only other thing you need are charcoal briquettes. That said, some formulas recommend the urine from a wino. I'm good in that department! LOL Enjoy! The briquettes must be ground very fine. Mix equal parts in thirds. Wham!

Not to pick on any one individual here but I see a very deep misunderstanding of Salt Peter, "NAo3."
Many of you state it is dangerous because it is an explosive.
Not true!
It is used in the making of explosives yes.
It reduces male randiness. Not true. Complete myth.

If you will note the O3 part of it.
This is what when mixed with the proper amount of fuel, charcoal etc it can become an explosive.
Charcoal must have oxygen in order to burn. You remember, burning is a reaction of something with O2.
So if you were to put charcoal powder in a closed container, "cartridge with a bullet in front." It won't burn! YA GATTA HAVE O2!
Throw in the right amount of NAo# with the Charcoal and wala, you now have fuel, "Charcoal" and O2 in the NAo3.
When you ignite it, the Charcoal reacts with O2 and it burns at a fantastic speed. Since it is contained in a closed container it builds up a great deal of pressure in a very short time. We call it an explosion.
Example in one muzzle loader 45 cal 22 inch barrel black powder rifle the measured pressure is over 12,000 psi in less than one tenth of one thousands of a second.
This is an explosive pressure in a chamber with a given weight of shot, powder and blah, blah. It is far short of being a completely closed environment.
If this same powder was in a chamber just large enough to hold it and completely sealed the pressure whoul far, far exceed the stated pressure of the weapon.
Other things other than Charcoal can be use for fuel with the NAo3 as the oxidizer. Example on the farm when I was a kid we mixed Ammonium Nitrate with Coal Oil or other slightly heavy fuel oil. NOT GASOLINE!!
This was put in a coffee can and inserted into a hole under a stump.
The hole was dug with post hole diggers very close to the diameter of the coffee can. Then the spaces were filled with loose dirt and water poured in to compact it. When ignited thee stump became a projectial and the small hole dug becomes a crater. It is very dangerous and should not be done by anyone I've seen the writings of on the blog.
I see no one stating anything even remotely showing enough knowledge to do this safely.
Don't learn this by doing. Learn it by reading and from some one knowledgeable and practiced in this art. In other words don't do it from instructions found on the Internet or a book. Learn from someone who has done this a lot.
Be safe, keep all your digits!

From what I've read here

btw saltpeter is KNO3, not NAO3. NAO3 is sodium nitate, saltpeter is potassium nitrate. Although, they are very similar.

first off you're credit went down the drain when you typed NAo3 which does not exist also i think you meant NaO3 which also does not exist and is far from saltpeter (potassium nitrate) which is KNO3 also it's an oxidizer which means that it help the fuel burn without the help of oxygen.

DONT'T USE CHARCOAL BRIQUETTES!!! Those contain a large concentration of clay and cause much more residue and less of a potent mix. Use any hardwood LUMP charcoal... this is all natural charcoal (oxygen deprived burning wood). You'll have much better results.

This is very good news for me! me and a friend are looking to make some smoke bombs, so we are using the 3/2 ratio of Salt Peter and sugar. Thanks for the info!

CountryGun Thanks for the Information on where to Get the Salt Peter but we Are talking Chemistry here. You DO NOT want anything in the mix that is not needed because of that Charcoal briquettes are not the best idea as companies add all sorts of things to the mix to make them burn hotter and longer not to mention start Quicker. For best Quality I would suggest Making your own Charcoal. I think we have all seen the Char-Cloth Videos on you-tube. Its simple to do. You're just scaling up the idea. Use a old popcorn tin drilling a hole in the lid big enough to let the hot water Vapors out without letting in oxygen to feed combustion of the hard wood. AND DO USE hard wood. Soft woods such as pine contain resins most of the time that contain Turpin's where we get turpentine. If you really want to go big you could look at how others actually produce their charcoal for their Metal Forge's. I've seen some as big around as a small pool the size really is limitless as long as you can release the water vapors while not allowing combustion of the wood used. I Would NEVER Use Black Powder produced with briquettes in one of my fire-arms.

Are you kidding? We should have a meeting and swap world domination plans.

I'm kinda young but I'm smart :D
I'm in :D

Lowe's, Home Depot, or just about any garden center. Look in the herbicides or stump removers.

Easier way (in case you are not a farmer and live in middle of city)! :D


Get an instant cold pack that clearly says it contains ammonium nitrate, cut it open and pour the contents into a container. If it's unused there will be a water pouch that you can discard. The rest of the pack is ammonium nitrate. Usually its coated in an anti-caking agent so it'll be off-color.

* If you're using an already used instant cold pack then filter out the liquid and let it evaporate until it's dry. The crystals will be ammonium nitrate.
Take 80 grams of ammonium nitrate and dissolve in 70 milliliters of hot water. This will take some time so be patient. It will take even longer in cold water, so use hot water when you can.
* If it has an insoluble anti-caking agent, you need to filter it off through a coffee filter after mixing.
Measure out 56 grams of potassium hydroxide, separately (see tips for procurement info). Add just enough water to completely dissolve the potassium hydroxide.
Add the ammonium nitrate solution to the potassium hydroxide solution, when both solutions are clear and ready. This step will produce large amounts of ammonia gas and must be done outside or in a fume hood.
Leave the solution in a very well-ventilated area (outside is best) for all the water and ammonia to evaporate. You can also boil the solution to dryness, just remember, it is still producing ammonia!
Now you have potassium nitrate! To test it, mix a small portion with an equal amount of sugar and set it on fire. Normally pure sugar does not burn but if the potassium nitrate works then it will flare up in a purplish pink flame.

whered u get the potassium hydroxide it sounds more dangerouse then saltpeter

I went to lowes and they had Spectricide stump remover there for 6 dollars :)

where cuz they dont carry in toronto lowes
or walmart

lol i almost want to tell you how to use it to make a missle, but i dont want anyone to get hurt ;-)

You can get it nonlinear from -ihaveadotcom.com-
I have bought from them and the pottasium nitratr worked great.

If you live in ChinaPotassium nitrate is more dangerous, limit the amount of purchasePotassium nitrate 99.4% of Shanxi 50kg / bag Colorless transparent prismatic crystal or powder Uses: used in making gunpowder, glass, matches, and used as fertilizer and analytical reagents, potassium nitrate, KNO3, a molecular weight of 101.11, is colorless and transparent rhombic or diamond The white crystalline powder, soluble in water. Mainly used in fireworks, gunpowder, matches, fuses, candles, tobacco, color TV picture tube.

Stump Remover! Home Depot! Go Now! But It Is Very DANGEROUS. Dont Let It Touch Your Skin And What Are You Using It For?

Someone told me that the absorbent crystals in diapers contain this. Is this fact or crap?

Umm diapers and crap... Kind of odd don't you think?

Potassium nitrate is one of the active ingrediants in smoke bombs and pyrotechnics im 17 and live in the uk i dont want to make bombs but i do want to make a smoke granade. if you want ill send you the ingrediants and methord and you can make your own

Hey! reckon u can send me some ??? that'd b ACE cheers.....

When I was a bit younger (30 + years ago) it was a main ingredient used by the country folks around these parts with pickling spices, and could be bought in 8 oz, one pound, and "barrel" amounts. I can't find it in ANY grocersy store anymore *sigh*

I need a little to make the sparks/smoke/lava for a volcano for a demonstration and it is just so hard to find.....

can u send me that recipe?also would organic hemp wick work as a wick?

if it has a an ember and stays lit

:( oh great, you make him sad!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!: ^ l

yea i use to make fireworks and stuff, but then i grew up and realized that blowing ur hand off isnt worth hearing a few bangs

you have to keep making bombs UNTIL you blow off your hand... and then you THINK about not making anymore.

And sometimes you don't learn your lesson, and make more!

What the hell kind of accent were they trying to do there? L

you can get jobs for making fireworks and earn alot of money doing it
