2004 Saltpetre - More Interesting Than You Think

I have been meaning to repost this for absolutely ages - I finally got round to it

[@gardencompost259]

As a teen , I tried my hand at making fireworks. The local pharmacy had most of the chemicals I needed. However, I ran the pharmacy out of saltpeter, so I had to turn to my homemade stuff. Fortunately I lived in an agrarian area, and a neighborhood sheep pen needed cleaned. And you get the rest of the story. Thank you for sharing this bit with us. I enjoy your posts, a lot.

[@ogi22]

Hahaha, What young people do to make things go "boom" 😁 Don't worry, i had my fair share of fun with saltpeter and sugar propelled things (we loved to put this stuff in hard liquor caps, poke a couple of holes and light it with a bit of match head stuff used as an ignition source). We even made competitions, who's cap will fly higher :)

[@joecrowe7062]

When was that u cant buy that from the pharmacy anymore, the good old days are gone

[@ogi22]

@@joecrowe7062 You still can buy saltpeter in a bulk in gardening stores ;)

[@CCoburn3]

In medieval Europe, there used to be people who made a living collecting urine. There were so many uses for urine. But to make saltpeter, they used the saltpeter beds you described. It's interesting that people used to know how to use "waste" products to create useful materials. We certainly need to do more of this. For instance, we COULD be using sewage sludge to create biogas instead of burying it in landfills.

[@WarkWarbly]

Interesting you mentioned this, as the county I live in is testing this as a renewable/green energy source. They mostly just bake into charcoal briquettes and then burn it in coal reactors. Kinda like a steam train.

[@VojvodinaNet]

khm, khm...they might be already doing just that :) And the water too :)

Biosludge - in US sold as 'organic' contains all kinds of chemical pollutants. So be aware that profit plunder operates any ruse to dump out toxic consequences to the masses as green virtue. 'Solutions' that are real become an effective mask or marketing pitch. fake 'solutions' are problems or toxic debts repackaged and sold as 'appreciable assets' or credits. Human ingenuity set in war & plunder - or getting for self-at expense of others (& whole) seeks always to game or hack the system, and the minds of all who depend on systems.

[@turkeytrac1]

In the part of Canada I live in, the sterilized sewage sludge is used as fertilizer on non root crops. It's used to amend the soil in which wheat, rye, and peas are grown.

you can also change the sheets for straw or chaff. If you make this mostly a waste reprocessing system, you can get more than salt peter out in some builds, but even more, after the leeching you can compost it, with most ash, and remaining materials are almost all fertilizers. leftover nitrogen compounds, broken fiber materials, rare earth oxides, and if you were careful about the lime amounts, useful calcium salts.

Nitrification bacteria convert ammonia into nitrates in aquaponic systems as well. The first bacteria turn the ammonia into nitrites, then the second turn the nitrites into nitrates.

Back in my early Internet days I had a thing for potassium nitrate. I used to watch how to vids on smoke bombs and had a go myself. Occasionally they fell over and shot across the garden lol. I'm much more grown uppy these days though. But I like to imagine theres still a file on me in some government department with the heading "harmless nutcase" due to the copious (probably not that much comparably) amounts of potassium nitrate I used to order on ebay.

[@TheBaconWizard]

It's also what traditionally makes cured meats (eg bacon!) pink when cooked. It is reduced by good bacteria (lactic acid bacteria) into potassium or sodium nitrite and then into nitric oxide, which binds to myoglobin in the muscle in the same way as oxygen does, thus, the same colour: Pink/red. This reduction process preserves the food while it's active, enourages good vs bad bacteria, and generally provides a safe environment while salt removes the water from the meat, the salt makes its own way-in (osmosis) and while the meat is air-dried or smoked. If anyone is concerned about nitrites remaining in bacon that they eat: It's a fermentation process, where none is remaining at the end. Vitamin C is added to be sure of this, in modern production, and anyway the answer would be to have a glass of orange juice or some tomatoes with it. Nitates and nitrites are also present in vastly larger quantities in green leafy veg (eg spinach) Don't BURN the bacon, however, or a lifetime of doing-so hightens the risk of cancer. Here endeth the bacon lesson, but between preserving food and gunpower, one can see that civilization has been founded on this substance in a big way, alongside several other important ones of course.

[@Hawkewood]

Nice, interesting tidbit.

[@exploreseafaring]

I'll never look at a bacon butty the same way ever again.

[@AlyxGlide]

using sodium nitrite & nitrate in food preservation is not traditionally from antiquity it is via our rather new additive curing process around the 1900s & is debated in safety as they are listed to generate higher nitrosamine carcinogens listed across food safety regulation .. & to say that they exist in higher quantities in leafy greens than processed meats is bizarre

[@AlyxGlide]

& if you believe that sprinkling sodium nitrite equates to sprinkling fennel seed then I hope you're not a chef..

[@TheBaconWizard]

@@AlyxGlide It is a fact. Nitrates have been in use for hundreds of years at least, as Potassium Nitrate, almost certainly thousands as my research in The Dead Sea and the production of salts for curing during Roman occupation lends further evidence for. And green leafy veg contain more of it than is used for curing, especially if they are somewhat light-stressed such as winter spinach. Not just slightly more. VASTLY more, like perhaps 6000ppm vs the 80ppm that is the minimum needed to cure (although unreliable at that level unless using NaNo2) note how some products are sold with this as a marketing point; beetroot juice for example. You maybe be confusing it with the fact that THE MECHANISM of conversion from KNO3 to KNO2 or NaNo3 to NaNo2 by bacterial action (respiration) was discovered in the late 1800s leading to artificial fertilizers and curing compounds. It is entirely possible although not always desirable to cure meats using only vegetable powder as I showed DEFRA while in consultation for them concerning proposed regulation of nitrites in organic curing. Celery seed power is one of the most reliable but is a common allergen and of course has a flavour although not as strong as one might think after curing. Furthermore, the final product in curing is neither nitrate nor nitrite but nitric oxide. This is ALSO produced during smoking from the combustion process itself and is the reason for a traditional "smoke ring". It is possible to cause that smoke-ring to cover the entire piece of meat all the way to the centre for smaller cuts as was a source of research I did for did for Danepak, but proved too expensive to do commercially (in their market) as special equipment is needed and it is a slower process. ALSO viable in technical terms is the direct addition of Nitric Oxide, however it is very dangerous as any leaks will result in Nitrous Oxide which is deadly. Not to mention that it is not approved for food use.

I came into this video with questions. I leave with them answered, but with more scientific enlightened questions on the brow of the hill. Safe to say, I have learned something, and left with the thirst for more knowledge on production and history of saltpetre. Thats a great format and enlightening!

[@JehuMcSpooran]

Farmers still do that thing with peas. My uncle who was a farmer was telling me a lot of farmers would plant a crop of peas and then mulch them back into the soil before they started to produce any pods as the pods growing depletes any nitrogen in the plant. Then they would sow their wheat crop soon after the mulched the pea plants.

I once went out in an old BMW car of a friend of mine, it was winter, we went walking in the snow and ice and after many hours arrived back at the car just as it was getting dark, on getting into the car I was astonished, has he started the engine, instant hot air came from all the vents, in a few seconds the ice just fell off the windscreen, when I asked what was going on, he said it had a Phase change heat store which dumps 45000 watts of energy instantly into the engines coolant circuit. After doing some research it was basically a box surrounded by Aerogel insulation containing a eutectic mixture of Potassium Nitrate and Lithium Nitrate, I would love to replicate it.

[@schinderiapraemeturus6239]

A topic of interest to me as well, it's crazy that we pay sewage plants to actually reduce nitrite and nitrates back to N2, would it not make sense to arrest the process once nitrates are formed and extract them? The Ostwald process is great but quite energy intensive. Thinking an aquaponic digester would speed up the natural process a bit, and nitrosomonas bacteria can be found in the brown slime algae that forms on the surface of rocks in a stream, especially where the stream pools a bit.

Thanks for this video. Very interesting. 30,000 chinese labourers in the early 19th century were tricked into believing they were travelling to the gold fields of California and were indentured on the Chincha Islands off the west coast of South America to mine guanno. A huge number died of accidents and lung diseases associated with the hellish conditions on those islands. Sailing ship crews would spend their off duty hours high in the rigging while the ships loaded, rather than suffer the horrendous fumes below decks. Small wars in the Americas were fought over possession of this stuff.

yes, sulfates and sulfites can be reduced back to elemental sulfur, and sulfides can be oxidized similarly. Calcium sulfate (gypsum) would be a readily available source. However for making black powder, I prefer modern substitutes that contain no sulfur whatsoever, i.e. Triple 7, Blue MZ,

Both nitrates and sulphur can be had in one form or other from a garden centre anyway as both are used as plant food. Nitrates I believe are used for strong leaf growth. Nettles will often grow where theres nitrate rich soil as well so as well as the soil beneath nettles are probably high in nitrates.

Who was it, I wonder, and why was it, that someone thought, we should kill a new baby lamb tip out it’s stomach, dry it, break off a bit, grind it up and mix it into fresh milk.
