About This Video:
I smelted iron from iron bacteria and then cast the iron in a mold to form a rudimentary knife, making this the first iron tool I've produced yet. The ore was a species of bacteria that lives by oxidizing iron dissolved in ground water. It appears as an orange/yellow cloudy precipitate in creeks and ponds. It's a very common natural occurrence and can be found on all continents. I collected the diluted ore and poured it into a large, porous ceramic pot I made. The water leaked out, leaving behind the concentrated iron bacteria "mud" like substance. I dried it out until it resembled rusty earth. It took a month to collect the ore for one 2 hour smelt, from a stretch of creek about 20 meters long.

Charcoal was then made simply by burning a pile of wood in a small pit and then extinguishing it with just enough water once it had visibly carbonized. It was quicker to make than the charcoal I normally make in a mound (1hr vs 2.5hrs) and took less preparation time making than the mound from mud. A small furnace was made and the multiblade blower (made in the last episode) was attached to it for air supply.

The furnace was preheated for an hour with wood and filled with charcoal at the end, using the blower periodically but not full blast. Then over the next hour, 3 double handfuls of charcoal (about 500g) and 2 single handfuls or ore (about 200g) were added every 5 minutes while blowing air into the furnace to burn it at this rate. Then there was a 30 min burn down still using the blower till the charcoal reached the level of the air entry. The total operation took 2 hrs. A lump of slag was taken from the furnace and broken up. Iron prills up to about 1 cm in diameter were retrieved. For the sake of experiment I weighed the iron produced on modern scales= 40g iron from an estimated 1.2 kg of ore. Even though this is a low yield by modern standards it is a marked improvement over my previous smelts that produced much smaller and fewer prills over all. I did another smelt that almost exactly reproduced this result (80g of iron stored). The increase in efficiency is due to the much better blower design (8 blades vs the original 4).

Next I cast the iron in a mold. The melting point of pure metalic iron is 1538 C. However, the iron prills I produced are cast iron, an alloy of iron and carbon where carbon is about 2-4% by weight. Cast iron has a relatively tepid melting point of 1150 C. Such a temperature is easily attainable in an open hearth with charcoal and a forced air supply. So, I put the prills into a triangular clay mold and put it into a simple pit forge that took very little time to make. Importantly, I made a special flat air pipe that spread the incoming air into a sheet that blew over the width of the mold to heat all of it evenly, a round one would only heat the middle of the mold and not melt it completely. Charcoal was then put on top of the mold about 12.5 cm deep and the air blast started. The fire became white hot, exceeding the 1150 C needed to melt the iron. The iron melted filling the mold and the iron triangle was taken from it.

Initially, I was going to make it into an axe head, but decided it was too brittle (cast iron is actually harder than pure iron but brittle) so I sharpened it into a knife. It took many hours of sharpening to bring the end to a point. It's not a sharp blade it works well for drilling holes in timber (like for making fire drill sockets). This represents the first iron tool I've made completely from scratch in the wild. Future experiments will focus on obtaining greater yields of iron, exploiting richer sources of ore and ultimately making better iron tools.

This isn't quite bog iron, but it's on its way to being so. Bog iron is specially when this same phenomenon has occurred in particularly low oxygen environments for a very long (potentially geological even) time period. Layers upon layers of these bacteria build up as a scum on the bottom of a bog which hardens over time into bog iron ore. These are also the environments in which peat moss lives, hence the term peat iron as well. So in short, what he harvested isn't bog iron, but if the water flow was slower and it was left to sit for a few thousand years then it would slowly become bog iron.

@Aaron B Fascinating, isn't it! Back when the lands of germanic people had a lot more swamps, it was how the "barbarians" in the north got a lot of what iron they did had. Most viking swords, for instance, were made from bog iron. They did know about mining, and some mining was done, but I guess this was a common man's way of getting some iron too, and probably cultural and/or convenient.

In terms of production, usually bog iron is already present in little lumps in the peat and so it is easier to harvest. I believe they would go and harvest peat from a patch of land maybe once or twice a generation to get the next formed iron out of it. (And probably use the dried peat as fuel etc)

These videos are genuinely so helpful for fictional world-building (not to mention fun to watch!). It's one thing to read about how to make clay or iron or tools etc from scratch, but it's different to actually watch someone do it. Plus the insight in the subtitles provides details that aren't mentioned in written sources. It provides an entirely new perspective that makes more basic world-building a lot more interesting to think about. Honestly inspiring, and I think it's helped get me out of a writing block, so thank you!

Primitive Technology
This is the first iron tool I've made. The method I used is reproduceable and relatively simple so the viewer should be able to get similar results to what I have. Watch the video with captions on to see information on the steps in more details. The ore I used is iron bacteria and it lives in soil everywhere though it only becomes visible when it becomes saturated with water. The viewer has probably seen it before when out hiking along streams but may not have known what it is. Any questions about the process let me know. Thanks.

There's 495 comments so I posted it on the main section too, but do you know what the reduction in charcoal to achieve pure iron would have been , roughly, and whether a clay crucible is viable for the same or a greater quantity?
BlightyBog 17 dias atrás
@Primitive Technology something you can do, is EVENTUALLY, that carbon will burn off, so long as once you get it cast, you don't liquefy it again, even keeping it at a red heat for... myabe 30, 40 minutes? (i'm unsure as i've never INTENTIONALLY tried doing this, usually i just accidentally turn carbon steel into wrought iron.) that will lower the carbon count significantly, even more so if you do some very gentle forging, as that "squeezes" the carbon out. maybe use a purpose-built mallet? i wouldn't use stone at first, as that might be enough force to outright crack the casting, but if it does you can always just recast it.

@Dokk Stigvel "That isn't cast iron. That is closer to wrought iron and very close to what mild steel is." It is cast iron. There are a number of reasons to believe that: 1) He used a lot of charcoal meaning that probably a decent amount was incorporated into the iron making it cast iron. 2) He says it's cast iron. 3) He was able to melt it suggesting a high carbon content.

I love this stuff. I made my own forge once out of modern materials of course. Got fire brick from home depot and ordered some furnace mortar, my design ended up looking like an engine block almost haha lower cavity to blow forced air and a hole in the back and split in the center of the upper cavity to direct air flow. I used an air mattress inflator and some black iron pipes to provide the forced air and mesquite charcoal for the fuel source and It got hot enough to melt good steel. Melted more that a couple half forged pairs of rebar tongs in that one haha. Love the content keep up the awesome work my dude.

@james grist It’s unfortunately not quite that simple. Cast iron doesn’t refer to just the shaping method, it also has a very high carbon content, which makes it very hard and brittle. This makes it unsuitable for forging, it’ll just shatter upon impact even when heated (hence why it has to be cast). To truly enter the iron age, he’ll need a better smelting process (mixing with the charcoal adds a lot of carbon), and possibly a better source of ore (the bacterial ore is very impure).

If you want to know how silly they were and how popular -> just read your comments. Exactly the same super low level of logic or consistency was in them and all that likes for your comments are a solid prove that ignorance and not using too much logic is as popular nowdays as it was in medieval times!

@Big Mike Bog Iron is my personal likely first forged iron candidate, as it feels much easier to stumble on than the bacteria goo. It is totally possible someone collecting clay for pottery collected it in a particularly gooey place, and when the eventual pottery was fired the goo turned into little iron pellets along with their pottery, and they went from there. Either way, it's amazing how much iron is in these bacteria colonies, and how it's an actually useful amount.

Well... Where do you think we got iron from? Lol there's a reason it took humans tens of thousands of years to go from the stone age to the bronze age, and then thousands of years from bronze to iron. We basically just did this stuff until we had enough materials to spur a new wave of technological development (which requires a surprise of material to work with).

It is so interesting the fact of a living metabolism that eats metals 🤔 even more knowing that you use that in your advantage to make a primitive knife 😌 ... man the honest and simplest idea of making something out of nature and seeing that work in the most humble way without being pretentious makes me feel happy and calm 🙏

@Justin Robertson Bronze is actually a lot harder to create than Iron, i can make Iron right now with a pretty basic understanding and easy to find ore. To make bronze i'd need to find copper and tin and i don't even know where i'd start going about that...

@D Murray Even if that is true (which it isn't), is that really a good way to judge how advanced a country is? Singapore is a world financial and economic hub, a pretty advanced place. 50 years ago it was a backwater port where a bunch of criminals and pirates hung out. They became advanced not because they invented a bunch of things, but by reforming their politics. It's not like countries have to independently invent everything they use. Africa in general is underdeveloped because it has been relentlessly exploited by colonialists for 500 years, first Europeans, now China. Hard to become an economic powerhouse under those conditions.

Hi, Iron smelting would have been much more efficient if there was some limestone next to it. (The melting point can also be lowered with other natural additives and the efficiency of the reduction can be increased.)

I believe this method of iron gathering was used even quite far into the renaissance. To my knowledge the majority of iron for the peasantry was bog iron usually forming under wet grassland by the same or very similar bacteria. Tooling got a bit more sophisticated of course, but mined ore was not particularly affordable for the poorer strata

@Extra Crispy Merriam-Webster gives "deviation of the expected value of a statistical estimate from the quantity it estimates" and "systematic error introduced into sampling or testing by selecting or encouraging one outcome or answer over others". Things like "unfairness" are not relevant to how bias relates to what I've been saying. "You arbitrarily conform to personal conjecture based on an opinion formed through personal history." History is *one* factor which *may* indicate degree or reliability but it's just one among many. "even a broken clock is right two times a day" I've only been saying that some sources are *more* *likely* to be correct than others. I've never claimed that some source should be expected to be correct with 100% or 0% probability.

@seneca983 We're talking about the definition of the word 'bias.' Webster defines bias as such, "an instance of such prejudice." Cambridge defines 'bias' as "the action of supporting or opposing a particular person or thing in an unfair way, because of allowing personal opinions to influence your judgment." The Britannica defines 'bias' as "a tendency to believe that some people, ideas, etc., are better than others that usually results in treating some people unfairly". You arbitrarily conform to personal conjecture based on an opinion formed through personal history. Whether or not it the legitimacy of the person's ideas are given credence through them having a golden ticket for the chocolate factory - or a membership at the local police station, you evidently prefer the opinions of 'certified authorities' over that of all else, in spite of the fact that this authority is not objective itself, and may - and almost certainly might have - private interests that potentially compromise their output by way of skewing it toward the things that they deem more important. AKA: you are biased, and no amount of hemming and hawing about it will change this fact; you might as well just skip to the point and go back to mooing and chewing on grass all day. Leave the big thoughts to people who can realize that even a broken clock is right two times a day.

@Extra Crispy "wikipedia is not the only source of information on things, and generally speaking when you resort to definitions on english words, you resort to dictionaries as opposed to public forums on information." Well, Oxford Learner's Dictionary gives the following definition: "the fact that the results of research or an experiment are not accurate because a particular factor has not been considered when collecting the information". Credentials and other indicators of reliability of a source is an example of one such factor; neglecting to consider it can result in bias. "Your bias toward favoring your preconceived notions" Considering the reliability of a source is not related to preconceived notions. You can evaluate the reliability of a source e.g. *before* you know whether the answer/information it gives supports the notions you have beforehand or not.

@seneca983 wikipedia is not the only source of information on things, and generally speaking when you resort to definitions on english words, you resort to dictionaries as opposed to public forums on information. Your bias toward favoring your preconceived notions is something that will inevitably lead you toward skewed perspectives, but I imagine this is something that you'll either intentionally ignore or fail to recognize for the rest of your life. I don't expect that you'd be capable of, let alone be willing to do your own information gathering anyway
seneca983 7 dias atrás
@Extra Crispy "Bias means the same regardless of what you're talking about. This is simply a case of you not knowing what you're talking about, and consequently your definition deviating wildly from the standards of the english language." You're mistaken here. E.g. on Wikipedia one can find the definition "a systematic tendency which causes differences between results and facts" which is basically what I've been using here with slightly different wording. I'm not sure how you'd use the word in the context of subjective matters but that doesn't matter here because that's not what I've been talking about. "Every single source that exists is literally all flawed in some manner." But often they're not flawed in equal amount so it's rational to give them different weights accordingly. "You look at different sources explicitly for this purpose" Yes, it's often useful to look at different sources but it also often makes sense to give some of them more credence than others.

@ShadowkillZ theory is nothing else but their collective experience for a few millenia in a scientific language. People like to think medieval people were brutes that had no idea of confirming their theories. That reflects in the view of science as "standing still since the Classic Period". In truth, the info they accumulated over centuries has birthed the theories and practice we use nowadays.

Ancestors had better sources of iron then bacteria infested mud. That being said, the thought+experimentation that goes into discovering the technologies is also a luxury, so it balances out

I'm a biochemist/microbiologist and I was like "oh he's utilizing iron oxidizing chemotrophs, that's cool" and then it hit me--someone figured out that this weird slime in a slow moving stream contains a useful element and, while such iron was rarely used to make implements, it was often used in creating primitive pigments. That just boggles my mind. Before the written word, someone figured this out and put it into practice.

Congratulations dude it's been a long road to get to this. HUGE respect. I love that this is scalable, you could just as easily make a full sized iron axe by increasing the volumes of everything. Maybe even a stream dam with miniature water wheel direct driving a furnace blower to get consistent airflow and higher temperatures.

@Magne M The superior durability of steel would have been the selling point. As far as weight goes, it's the same, because of course steel is just iron with a wee bit of carbon added. But that little bit of carbon can do wonders for strength and the ability to hold an edge. IIRC, even once the making of steel became widespread knowledge, simple metal items were usually still iron, but a weapon was going to be steel - because your life literally depended on it.

@7. 62 _"what i am saying is they probably wouldntve bothered with the extra work"_ Well, it's obvious you're not a tradesman of any sort. Or anyone who builds anything for a living. Certainly not with an attitude of "I'll do a comparatively quick-and-easy job now that'll just make for more difficult maintenance down the road rather than putting in the work of a proper job the first time around and have easier maintenance."
