I had a hell of a time finding over the counter KNO3 so far. The only source I have been able to find is from those damm mole smoke bomb things. It is hardly a cost effective way of obtaining KNO3, but at least they come with a couple pieces of cannon fuse.

If you are really determined.....


Very large burlap bags(100 lbs plus) can be filled to overflowing with wet(but not dripping) dung.

Keep the outsides relatively clean of dung.

The bags can be hung from a tree (just keep them from touching the ground)

as the water from the dung evaporates it will leach salts onto the outside of the bag.

These salts contain a high percentage of nitrates but also contain sodium salt.

The salts must be scraped off and dissolved in water and filtered to remove solid impurities, and then boiled and repetitively cooled/filtered until all/most of the sodium salts crystallize out.

The remaining supersaturated will be mostly pottasium nitrate, at least pure enough for gunpowder.

This is the original preparation from the middle ages. (except they usually used very large and long rows surrounded by a "fence" of the homespun cloth).

They wanted to maximise the use of the cloth because textiles were extremely pricey back in the days when it was sheared, spun and woven by hand labour.




Arguing on the internet is like running in the special olympics; even if you win: you\'re still retarded.

KNO3


In the U.S., I bought a 50 LB bag of KNO3 for $19.95 + $20 HAZMAT fee
+ shipping. The total cost was $43 + change. I calculated a per LB cost
of just under 87 cents. This is the link:

I bought a Greenlight stump remover and it has a smell, like fertilizer or something.
Potassium nitrate doesn't have a smell. It might be cotaminated because the cap was kind of messed up. Well is there any way of testing if its KNO3?

KNO3


Any KNO3 I've ever bought or made does have a smell. Maybe my nose
is sensitive to nitrates. The taste of KNO3 is cool and bitter.

KNO3


Sorry for double-posting. Please forgive me. Something I should point
out about KNO3 - don't swallow that shit because it won't kill you -
unless it's a massive dose. But it will definitely interfere with your sex-life !
It's not called saltpetre for nothing !

Just to elaborate on Madhatter's post, Saltpetre was once used as a 'medicine' to reduce the sex drive in men.

Also with ingestion of KNO3 there is also the risk of nitrite poisoning.

In regard to using saltpetre to inhibit sex drive I tried this once as a teenager (ate probably a gram or 2) - it didn't work. It would probably work now.

Huh? Why would anyone want to kill themselves?

anyways I read in this book and it said that saltpeter was actually used as an aphrodisiac. Wierd. They stopped using it after they foud out it was bad for you.:D

Can you send me the analysis of the 99.5%KNO3?


Quote:
May I get a analysis of the product . Then ,if possible I want to some samle,ok?







So, it dissolves more so in boiling water than cold and it wont dissolve in absolute alcohol.
I think I need to put some backed epsom salts into that bottle of methylated spirits for a few days and then wash my stump grinder in it whilst slowly heating it to about 55 deg C. wash rinse wash rinse.
then see what is left. ( I am assuming you have weighed your product before, and will weigh after)
Then a boiling water wash, dissolve, then into the fridge, harvest xtal's boil reduce freeze, etc etc.
This is assuming that the major other ingredient is Urea, which is a HUGE source of nitrogen.
This is because urea CH4N2O is very soluble in Abs Alcohol Pot Nitrate isnt.
These are the solubilitys for urea.
1 Gram dissolves in 1ml water 10 ml 95% alcohol 1ml boiling 95% alcohol 20ml Abs alcohol 6ml methanol 2ml glycerol almost insoluble in chloroform ether soluble in concentrated HCL..
So, there you go, enough info to start purifying your "stump remover"
I personally think that a more effective stump remover using KNO3, whould be to mix it with sulphur and charcoal. LOL

Potassium Nitrate


I have 1 5lb box of Nitrate of Soda 16-0-0 and 1 5lb box of Muriate of Potash 0.0.60. I was wondering what would be the procedure in mixing the 2 for making Potassium Nitrate. What would be the weight of mixture, what would it be dissolved in and how would you dry it out. Is it possible?
Thanks in Advance!

Really off topic but Potassium Nitrate ingestion poses a high probability of permanent reproductive disorders, and not the short-term inhibition of sex-drive. It is investigated also as a mutagen, probably due to its metabolism in the body which converts it to the more toxic nitrite.

The reaction between NaNO<sub>3</sub> and KCl would result in a mixture of two highly soluble salts, which is very difficult to seperate. Fractional crystallisation is fruitful only when small quantities are used. Carrying out fractional crystallisation for large quantities would result in a loss of time. Better use the NaNO<sub>3</sub> as is.




Theory guides, experiment decides.

KNO3


Before I found a cheap source of KNO3, I made it by mixing NaNO3 and KCl in a
ratio of 1.15:1(or 23:20). Mix with boiling water. I use 51 g NaNO3 and 43 g KCl
for every 200 ml boiling water. Chill to 0 C. Yield is 45 to 46 g KNO3 or about 77%
of available KNO3.

A better and cheap way of getting KNO3!


KNO3 is not an expensive chemical.In south asia,specifically in Pakistan it may cost as cheap as US $1 for each kilogram.It is commonly used in greek pharmaocopia as a urinary steriliser.I think you may find it if theres any such clinic around you.:D

Hi-Yield Brand always worked for me.:D I bought it at ACE(R).:D The MSDS says it is 95.5-99.2% PURE :DPotassium Nitrate.

aquisition of Kno3


the easiest way to get high quality potassium nitrate is to by the fertilizer grade, and then process it into the explosive grade, the problem with standard fertilizer grade is that it is often coated in various greasy waxy types of coatings in effort to slow down the release into the soil hence "FERTILIZER".
so anyone wanting pure kno3 will then need to dissolve the kno3 and filter it while hot thru filter paper and then repeat a few times and then boil it all into a super saturated solution and leave to evaporate on a suitable surface, then cook the shit outta it in the oven at its maximum temp (I AM NOT RESPONSIBLE FOR WHAT HAPPENS, IT HAS PROVED SAFE IN AN ELECTRIC STOVE) to drive of any remaining moisture as kno3 is hydroscopic
1/2 an hour should be sufficent.
WARNING: ammonia fumes will be created from this process and while not dangerious can be a extremely overpowering smell, as always exercise caution.

Greenleaf CO is a good source for K-nitrate. It is uncoasted and sells for $30 per 25kG bag. This is explosives grade material if you can power it up further.

licence/ ID needed to buy withing Canada.

Ammonia ?


Miseryland, what else is mixed in with that KNO<sub>3</sub> that would produce NH<sub>3</sub> ?
The greasy shit you refer to is probably wax - I would recommend filtering with
ICE WATER to make sure the wax remains behind. The KNO<sub>3</sub> I get from
http://www.atlantishydroponics.com doesn't have this problem.

I cannot find any good materials in my town, found Grant's Stump Remover however its not very pure and doesnt work that well, i just found Bonide Stump Remover however there are no ingredients labled on it, has anyone heard of it? If so does it work well?

Grant's stump remover is the good stuff. Search around here for the extraction technique. Bonide is completely worthless.

Bonide is sodium pyrosulfite IIRC. A good reducing agent (dissolves in water as sodium bisulfite, so acidic and reducing) but certainly not useful for pyro.

Most drugstores I checked had this one...


Something like 8 out of 10. If you want lots I guess it isnt so good but for general chem 100 grams for about 4 bucks was ok for me and I was assuming it to be pure...
Interesting point.. seems all chems in Montreal drugstores are made by Atlas Labs. Must be nice that no competition thing. Just not for me. lol
