Well it can't have been that great a weapon if he had to resort to the old hitting-over-the-head-with-a-big-rock technology! :)

Definitely a superior life-form though - never lost his sense of humour whatever the universe threw at him [8D]

Hi
Phorphoresence is produced by phosphorous.

Has anyone tried to extract salt petre from dung?

best wishes

Actually Phosphorus isn't a Phosphor, just to be really confusing. It does glow in the sort of way that phosphors do but this is actually due to it burning very slowly in the air.

I have tried extracting it from Compost *home made, generally veg waste and plant matter* it was about 2-3 years in the making so i just put it in a plastic tub at the bottom I put some holes but in order to keep the stuff from dropping out I used an old cotton T Shirt that I had spread about 5 desert spoons of wet ash from the fire pit. So it now had an ash filter, also I now had a VERY stong cotton T shirt as UREA strenghtens cotton when wet *saw it on shanghai noon and had to look into it*. I put about 1 letre of water through the mix of compost and then finaly it got through the ash filter, leaving a nasty looking and smelling water   [xx(]. So I then Boiled this down to about 1/12 of its original volume, left it to cool and then poured it into a ceramic bowl to evapourate the reminats of the water. End Result a very low yeild mix of Nitrates, practiality 2/100 id say, on a large scale the yeilds could be potentially fantastic. My compost could have been better if I had left it soaking in piss for a week or so, but i really dont want to smell boiled piss when I fire a cannon and hopefully neither do you lol

yes but really why the hell do you want to make it that way, just buy it.. you will also get a load of impurities such as other nitrates potassium carbonate from the wood ash and if urine was used you would get urea left too.

You can buy this from store who sell supplies for making sausage.  I think it is used to preserve meat.  We used to buy it by the pound from our local drug store.  It's a real cheap oxidizer.  We used to make smoke powder from it too.  You could mix it in equal portions with sugar (a hydrocarbon) and light it with a match.  Large amounts of thick white smoke.  We are all lucky to have lived long enough to talk about this stuff.  How many of us were very lucky in our backyard chemistry classes?  I was.  I found a source for magnesium once and decided to light it up along the side of my parents home.  It was a night of course so nobody would see us.  Right.  My parents home lit up like the mother ship was overhead.  I was grounded for weeks after that.

hey, i was bored and i cant sit still for 5 minutes so i gotta keep busy or i tend to break things hahaha, besides its cool to see what old BP would have burnt like compared to the new compositions. Think i might try and refine some Nitrate again this time on a bigger scale so i get somthing worthwhile. Big mug if you think Kno3+sugar smoke mix is good you would cry at the perfection of a 1g flash charge in a lighter case, its a good container due to the fact its built to withstand preasure 1g wont come close to filling the container as we all know you need to give it some expansion space for it all to ignite. i like to burrie them, but i have set one off under a baked beans tin *empty and cleaned* it fired it somthing close to 40ft in the air and penetrated the metal of the can Mucho Funo

Dude!
Saltpeter(KNO3) is found as a mineral and is common in China.
Chinese might have gotten it this way

"The people who will succeed are those who see the invisible and do the impossible."



There are actually two forms of saltpeter:  regular saltpeter and Chilean saltpeter.  Regular saltpeter is potassium nitrate and is primarily found in India, with smaller deposits in Bolivia, Italy, Spain and Russia.  Chilean saltpeter is sodium nitrate, and is primarily found in (you guessed it) Chile.

These natural sources are no longer industrially important, since we can now make the saltpeters more effiiciently from other sources.

I belive that at one point there was alaw that said you had to collect all the urine made in your house and give it to special urine collectors who would then make saltpeter with it.

Re: potassium nitrate. Here in England, in bygone days, they used to collect urine and then, I think, turned it somehow into alum, used as a mordant in the cloth-dying process. I think they turned the alum into potassium nitrate, tho' my memory's poor. Gunpowder was first used by English at the Battle of Crecy in 1346(?)-- crazy what one does remember.

Wikipedia states " A major source of Potassium nitrate was the deposits crystallising from cave walls " and also "A popular misconception is that potassium nitrate is an anaphrodisiac and was added to food in all-male institutions. In fact, potassium nitrate has no such effect in humans."

Potassium Nitrate manufacture:

1. Place a charcoal filter at the bottom of a large strainer. You can make a charcoal filter by spreading fine wood ash  between two pieces of cloth.
2. Fill strainer with nitrate-rich earth. The best sources of rich earth is well tended farm lands and decaying cellar floors.
3. Pour boiling water slowly over the earth.
4. Collect the water that drips out of the the strainer.
5. Strain the sludge out of this water.
6. Boil off half the water allow to cool.
7. Add an equal measure of alcohol to the water.
8. Filter through paper. (i.e. Coffee filter)
9. White Saltpeter crystals will collect on the paper (if you couldn't guess this is the potassium nitrate.)

I don't know if this procedure works, never tried.

I saw this on Tv. it involved getting a bucket, filling it with soil from your garden, peeing on it, then waiting a while. when it dries there are small white crystals left behind. and apparently this is saltpetre. never tried it though. kinda ties in with whats said above lol

Urine is extremely high in potassium and nitrites, so the creation of potassium nitrate from urine is very possible.  I think that it was often filtered through buckets of straw in order to be synthesized.

Yes. I would worry very much in that case!

I think you need to use stale urine - it was made in a heap of manure kept moist, but not wet so it is oxygenated. It is also mixed with wood ash which will provide the potassium. Bacteria then oxidise the urea to nitrates and you then after about a year you wash out the potassium nitrate with water.

you are correct, Dave. Also the morning urine of heavy drinkers was prefered. Saltpeter is produced by bacteria that feed on decaying organic matter; the ammonium-rich liquid produced by heavy drinkers enhanced/s bacterial activity

I once heard when I was a boy (1946) that in the past, in Tudor England, when they cleaned out their Mansions, the straw on the floor was collected by the Saltpeter man.  I can well believe that.  However I was talking to a real 'expert' on Tudor England & he hadn't heard of it.  Can anyone out there enlighten me on it

I think at one point in Paris, the citizens were required to dump their urine into pits for this purpose. I have not been able to find a reference to confirm this.

Saltpeter is a mixture composed of many substances extracted with fire and water from arid and manurial soils, from that growth which exudes from new walls or from that loosened soil that is found in tombs or uninhabited caves where the rain cannot enter. It is my belief that it is engendered in these soils from an airy moisture that is drunk in and absorbed by the earthy dryness..
