Primitive Technology: Iron Bacteria Cement (no fire/water insoluble)

[@primitivetechnology9550]

I came up with the idea of iron bacteria as a cement when I read that bog ore (a solid mineral) was formed from iron bacteria. So I shaped the bacteria into pinch pots and dried them to see if they set hard and wouldn't dissolve in water afterwards (remember no fire was used in this whole process). Surprisingly it worked and formed these water insoluble pots . I'm not sure on the chemistry behind it but I think it's due to water soluble iron 2 oxide in the bacteria becoming water insoluble iron 3 oxide when they dry out and oxidize. This reaction probably causes the material to cement together. It might be a useable mortar where iron bacteria is abundant.

Bog ore is common in areas of Sweden and Norway. It was an old source of iron for norsemen. The technique for accumulating and smelting it was nearly lost, but got passed along to a few people who were able to write and draw out the fundamental pits and tools necessary to accomplish the task.

Your video unlocked a core memory from my past that I had almost forgotten, and it was such a powerful and emotional experience for me.

Truth

[@Salbren_boi]

The unique variety of cement the guy has made on this channel is amazing to me. not only has he done actual cement in the video where he makes lime from shells, but he also came out of nowhere with a recipe using woodash, and now he's doing this. When will we have enough lol.

[@wesleyrm]

Yeah, seashells are basically calcarium. He never did it with calcarium from rocks, limestone, though. Maybe he can't find them nearby? Also, bones are calcarium too, don't know if it would work to make mortar from it. It's all about decomposition of limestone, CaCO3 to quicklime, CaO, to be slaked to Ca(OH)2, lime. What truly surprised was that potash/woodash could be used instead of lime. I think his is the only channel that showcases it and I saw the video by chance while searching for limestone/seashell cement. No sources mentioned using ash in my searches. Well, K2CO3 is probably a good substitute for CaCO3. Thing is, Ca(OH)2 is a liquid, which makes it mix well, then it slowly recarbonates back to CaCO3. According to some sources, what makes it a better cement is its restorative properties when rains come. It makes the Ca(OH)2 enter que aquous solution, fill the cracks and slowly solidify back to CaCO3, restoring the material. Fixing cracks. Don't know it that's only theory, though.

[@Salbren_boi]

@@wesleyrm I don't have alot of knowledge on chemistry like this, but this kind of reminds me of the discovery people found about Roman concrete a while ago, where they had small chunks of lime or limestone in the concrete that would repair the concrete when it cracked making it last way longer then modern concrete.

[@wesleyrm]

Oh, my blabbering is actually right this once, the cycle is limestone, quicklime and lime, then back to limestone. The steps are calcination, slaking (hidratation) and recarbonation. In portuguese, calcination is a pyrolisis, that is, burning without reacting with oxygen. That is, decomposition under fire. NOT COMBUSTION. Combustion requires oxygen and produces energy, the fire. Pyrolisis reactions consume energy, using the fire, the opposite. But pyrolisis in English is for organic compounds only. Makes no sense for it to be restricted to organic compounds! Etymology: pyros, fire, lysis, breaking down. Portuguese wins this time lol. French is on the same "wrong" bandwagon. Maybe Portuguese is the odd one out on this haha.

[@ludi3444]

Iron is technically easier in almost every regard except capability. However, bronze rose as an improvement to copper tools, and copper is easy to melt, to the point where it can happen by accident.

[@knightshousegames]

As I understand it, it's a misconception that all of humanity progressed on the same linear tech tree everywhere on earth where humans ended up early on Apparently some places just skipped the copper and bronze ages entirely and skipped straight to iron If anything, given that Copper and Tin were generally sourced thousands of miles away from each other, that was a far more impressive discovery

[@torg2126]

@@knightshousegames you're missing the developments of the Copper Age. Arsenic hardens copper immensely, and also works on bronze. Chromium can give a bronze blade one hell of an edge, far stronger than work hardening will. Zinc, of course, makes brass. There's plenty of alloying metals that strengthen copper, allowing the use of copper alloy tools all over the world. Iron, however, is extraordinarily hard to refine without charcoal, requiring far more heat to refine. It was probably the discovery that iron ore contains the same material as iron meteorites that allowed each localised jump to the iron age to happen.

[@knightshousegames]

@@torg2126 Interesting I mean, just in general, not everyone had the same linear progression, like "first we have stone tools, then we have bronze tools, then we have iron tools" Like some groups went from stone to copper, some skipped straight to bronze through trade, some stayed with copper and never went to bronze, before skipping to iron, etc.

Something I wasn't aware of until recently (was reminded of this since you showed it on the video) is that a slime mold is one giant cell with hundreds if not thousands of nuclei.

In one experiment, a slime mold was used to create a theoretical mass transportation map in Japan by using sources of food to represent population centers. The shape of the slime mold ended up being quite similar to the actually existing mass transit map of Japan.

@@boretrk Not entirely true, the amount of iron in regular soil and rock is so incredibly tiny it’s functionally impossible to extract.

Here's a thought for you. Filtering water, you'll need 2 pots and some rope. Place one pot with the bottom, higher than the top of the bottom pot. Place the rope in the top pot, overhanging the side and over the bottom pot. The water will wick up the rope, then when there is enough water in the rope, it will syphon the water out of the top pot, filtering it on the way. Perfect if you need to remove sediment without actually worrying about pouring the water.

I'm curious to see if firing the pots further in this current state would make them stronger or weaken the bond. I'm unsure of the science behind it but it seems like it might be a viable way to make upgrades to your tools like ceramic iron arrowheads or a drillbit to dig into wood easier for when you want to make holes for structural reasons.

Don't forget you can turn on the closed captions to get an explanation as the video plays.

Siempre es un gusto ver tus videos. De lo mejor que hay en KZbin.

[@juandavidquiros3521]

ehmm si

[@eaglethefox]

you should be awarded a phd in primitve technology for all your work and research

[@thatcanuck5670]

Certainly an interesting medium for pottery, any project plans for it?

[@mattparker9726]

5:12 what would happen if you fired these pots? Or if you mixed in 50% clay by weight and then fired them?

[@OfficiallySnek]

Today I learned that "cementitious" is a word

[@agriyantoemilio2453]

This man really took a science to another level

[@theavaliengineer]

Do you think it would be possible to form some form of culture of the iron bacteria using the equipment you have? It would be an interesting experiment - if it works, you might be able to get a more available source of iron.

[@joda7697]

You'd certainly have to provide something for the bacteria to accumulate, something that dissolves in water and contains iron. But yeah, would be really interesting to see!

Um dos melhores canais do you tube

[@MrVajco666]

You are the best. I wanna do something similar so badly.

Многие не понимают, но суть видео глубже чем вам кажется, у вас на глазах пример трансмутации элементов до железа. Алхимия простыми словами. Т.е. все месторождения железа могли быть ранее болотами, где жили эти бактерии и где они тысячи лет в качестве отходов производили железо.

Always love your videos glad to see youre back. Will you be using this method/material in future projects?

[@elitster]

Wonderful! Thank you for your content!

[@jakobpueh1091]

0:30 is a big powermove on those fake "Survival Building" Channels who somehow always build swimming pools. Gotta love it

[@gath1986]

Cementitious, 50 years old native English speaker and never heard it before! Love that!

[@simonnordberg162]

I'm so happy you're back uploading videos again!

[@bergerle]

Don't forget to enable subtitles!

[@ulysandres]

Amazing as always 😮

[@charlesguffy56]

Man I love your videos! For the part where you're waiting for the bacteria to settle--do you use any natural clarifying agents to induce flocculation? I know lime/calcium oxide and hydroxide can be used as clarifying agents, I was just wondering if that would help speed up the collection/separation process Thank you for the incredible videos!

[@AutoNomades]

👌gelatina and some water weeds can do, also

[@mickgatz214]

Good to see you back! Hope you got things sorted with YT. Cheers!

[@TheNowylepszyszatan]

I am impressed how patient you are for all those primitive works.

[@thepersonwhocomentz]

I'm interested in the impact and fracture resistance of this versus typical cement. Would you be able to make, say, a hammer head or a mallet out of this? It would be nice to bypass the need to make something like that out of solid iron.

[@Videoswithsoarin]

it make be stronger than cement but it and cement are both too brittle theyre just break anyway

[@lukasuhlenkamp9850]

I wonder if there are any historical examples of this iron bacteria being used as cement. I'd imagine it would be pretty useful as a mortar for underwater construction, though i don't know enough about masonry to guess if it would have been strong enough to be a useful alternative to other mortars available in the past.

[@AutoNomades]

It seems to need to dry to work, so i don't know if the mortar can take underwater....
