At this time of beer, i actually fail to understand the Question.
I'll read it properly tomorrow.
The Objective is to make a Useful amount, like in a bottle, which you can use some, and there's still some left in the bottle, and not just a drop.
Oh. While we're at it, any process that will take half a lifetime to make 100ml will be a bit pointless too, as by the time the process is verified,
we'll all be dead( 0.5 lifetime * 2 = 1 lifetime).

OK, I'll explain in terms of liquor: If one beer can = one vodka shot = two happiness points (probably wrong) and if the challenge was to produce two
beer cans (four happiness points), then would it be OK to produce two shots of vodka (also four happiness points) and not have to dilute it to the
piss tasting liquid slugged by 41% of Americans on a simi-regular basis.

Yeah I would think so because you could dilute the vodka to beer levels easy enough.

Crude potassium nitrate can be produced from the soluble portion of wood ashes (which contains potassium carbonate) and the calcium that can be
crystallized, as has been said earlier, from fermented urine or dung. Then you can calcine it with the proper minerals in a retort or use homemade
sulfuric produced from sulfide ores and distill out the old fashioned aqua fortis used by alchemists.

We're going all alchemy here. I never interpreted it like that.
I thought the objective was convenience rather than low tech. Correct me if I am wrong, but I don't see any prohibition against nitrates per se --
provided they may be found at the supermarket and are not pure or concentrated. I assumed that pot-plant fertiliser from aisle 19 would be allowed.
Aga, care to clarify?

If it was then so would be sulphur from the garden center or whatever, I think the point being just because you can get X fertilizer from Y shop in Z
isle dosnt mean everyone can. I thought the point of the challenge was to come up with a method that makes it possible for just about anyone. Not
every region or country allows nitrates in fertilizers as such.
The prize is pretty high so I would expect the challenge to be just that, a challenge! As soon as you start using nitrates etc in fertilizers you get
into a situation where someone somewhere wont be able to get it. I see it more like a desert island situation, get creative use whats around you or
easy to get. 250 Eruo is worth some effort surely?
As has been said pissing in a paint can will get you nitrates, ok not everyone has a pot to piss in, but they could use a compost pile.
Just my 1 Euro. Actually I think its pretty clever challenge, its a real test of ingenuity. I can get the nitrates bit but some the other parts are
proving a bit tricky.

Lo-tech will work better.
Just-buy-some-hi-tech will not work at all.
Sulphur is generally pretty pure, so No, sulphur from a shop, or travelling gypsy, is not allowed.
There *are* other ways than to just distill a nitrate with conc sulphuric, or zap the air for a while.
Seeking to make a nitrate and also sulphuric from stuff other than Ebay is a definite sign of Stale Thinking, as if that's the Only Way.
Think Outside what you already know.
Apply what you know to HNO3 and walk backwards from the lab, and out into the real world, with eyes still focussed on the HNO3.
The objective is what it is, so if you make super pure nitric from a car tyre and a bullfrog, it must be diluted to piss-weak strength for the 100ml

I stand in Awe of expert Chefs who can make a delicious meal from almost Any ingredients.
Michelin Stars were originally awarded to Chefs who could make Boef Bouginon from old car tyres.
1 Star was a bit rubbery.

I see you have found a practical application for your wife's horses.
Me, I think I will use bullshit and follow this procedure.
I'm sure to win this one!

Yeah. I think I will forgo the biological waste products route and instead focus on commonly available supermarket products. It is going to be a bit
of a gamble because OTC compounds vary so much from place to place.
Still, the stated goal is to have a simple procedure starting from items that are readily available to most people worldwide. That goal interests me.

If I buy fertilizer that contains nitrate salts, but is contaminated with other stuff (urea, ammonium sulfate, potassium salts, etc.), can I still use
it for this challenge? The fertilizer I'm thinking of is about 40% ammonium nitrate.
Also, I think I have found a way that, though inefficient, should be remarkably easy.

In most parts of Oz, OTC fertilisers are restricted to 7.8% nitrates anyway. Fertiliser just isn't that practical a source for us here.
I have some other thoughts in mind but I still need to do some reading. It might not be practical for me anyway. But I will be interested in the
submissions when they come in. Bound to be some clever ideas.

Think about it this way: If it were possible to make nitric acid out of table salt, one could always have nitric acid when needed. Table salt will
never be restricted or banned in any (normal) country of the world. It has so many uses in the home that it is available in any store. It is also
cheap. Those are the ideas.
One might have access to nitrate-based fertilizer, but what if one's store stops selling it? Availability of nitrates varies widely from one
locality/country to the next. Urea is, as far as I know, the default fertilizer that is available everywhere that ammonia and nitrates aren't. It is
gradually replacing nitrates in various applications. One's instant cold pack might be ammonium nitrate one month, and then something else the next.
I think the idea is to improve the availability of nitric acid to the common amateur chemist. This can be done by developing a usable method that
uses common OTC materials that anyone can practically acquire.
As seen from aga's original post, the idea isn't to make large quantities, or to make very concentrated acid. As such, the ideas
that result from the competition will (hopefully) be of limited use to someone who wants to do damage to something or someone else.
Personally, I use nitric acid to partially oxidize various alcohols, as part of my work in synthesizing imidazolium-based ionic liquids. A liter of
acid every week would basically equate to $100's of dollars worth of ILs. These ILs are generally unavailable unless one does business with Fisher.

Since when? 3 years ago I walked into a fertiliser/agricultural shop in sydney and bought a 25kg sack of KNO3, no questions asked. Have things changed
since then?

I looked at a packet of fertilizer in the supermarket today. It had two separate labels on it depending on sale location. 7.8% for all states except
WA. 20.2% Nitrates if sold in WA. I did not see any other products that had higher nitrate content. (Nor do I recall seeing any recently.) I
inferred that there must be some regulatory restrictions to have duplicate labels like that. It might be a supermarket thing. (I would expect
something a bit different for an agricultural supplier but that would definitely be outside the scope of this challenge.)
I am sure someone more knowledgeable will be around to correct my assumption.

Does guano from the largest urban bat colony in the world count as OTC?
I'm only 4 miles from it and the soil under it is surely enriched with nitrates...

Only if someone gives it you over a counter. Picking it up yourself just isn't OTC!

Regarding the fact that some people can only obtain fertilizers with a low nitrate content (7.8%), as long as the fertilizers can be purified, that's
not really a problem.
I think nitrate salts are pretty much the only viable starting material, since the Birkeland-Eyde and Ostwald processes are out of the picture.
Ammonium salts and urea are the only other common sources of fixed nitrogen, and bacteria are the only low-resource way to get those to nitrates
(chemical oxidation of ammonia requires catalysts that don't meet the challenge requirements).
I'll give away my process, if anyone else wants to try it:
Calcium nitrate decomposes when strongly heated, and one of the products is nitrogen dioxide gas. Using lime made from limestone where I live, and
ammonium nitrate from fertilizer, I can get calcium nitrate. I then can heat it until it decomposes and absorb the gas in water. Using sulfuric acid
and distilling would be more efficient, but this method doesn't require any acids at all.

Hmm... good idea... I
might have to get down there too if it's allowed.
It would be nice if it counts, although it is somewhat of a "local specialty" being as most cities don't have bridges full of bats. Aga?
