About This Video:
I made 3 furnaces from bricks using different configurations to test their effectiveness. The benefit of using bricks to make a furnace is that it's quicker, easier, re-useable and portable relative to a furnace constructed in-situ from clay. This is because the old furnaces crack and need repairs where as the brick ones can be assembled and re-assembled with any broken bricks being swapped out as necessary. Also, the shape and height of the furnace is easily changed by adding/subtracting or re-arranging bricks.
The first furnace used a square plan with the bricks laid on their sides with a inner cross section of 18 cm square. A 2.5 cm diameter tuyere was used and about 15 g of iron was made. The second furnace was the same but used a 5 cm diameter tuyere. It made about the same amount of iron. The 3rd furnace was a haexagonal plan furnace with a diameter of about 22 cm. The bricks were laid on their ends for this type. The smelt yielded the same as the square ones for the same input of ore, charcoal and effort.
I'll probably stick to using the square design made from bricks in future. Things I may try later would be to increase the height of the furnace by adding more brick layers. I'd put in all the charcoal and ore for the smelt after preheating. Then I'd be able to operate the smelt without the interruption of needing to charge the furnace every 5 minutes with ore and charcoal.
In conclusion, bricks make a useful furnace in a shorter time and with less difficulty than in situ made furnaces, are re-useable and can be disassembled and rebuilt in various locations if needed while the bricks can be stored out of the way when not in use.
About Primitive Technology:
Primitive technology is a hobby where you build things in the wild completely from scratch using no modern tools or materials. These are the strict rules: If you want a fire, use a fire stick - An axe, pick up a stone and shape it - A hut, build one from trees, mud, rocks etc. The challenge is seeing how far you can go without utilizing modern technology. I do not live in the wild, but enjoy building shelter, tools, and more, only utilizing natural materials. To find specific videos, visit my playlist tab for building videos focused on pyrotechnology, shelter, weapons, food & agriculture, tools & machines, and weaving & fiber.If you want a fire, use a fire stick - An axe, pick up a stone and shape it - A hut, build one from trees, mud, rocks etc. The challenge is seeing how far you can go without utilizing modern technology.

This really puts into perspective how _precious_ the earliest metal tools must have been.
Quite so. Smiths in ancient times were elevated to an almost mystical status in their community. They took seemingly useless rocks, and with the power of fire, transformed them into useful tools. Iron tools (and weapons) were *extremely* valuable. Iron was once thought to only be found in meteorites. Tools made from meteoric Iron became relics, as they were extremely strong and came "from the stars."
That's because aliens taught us metallurgy
And it'd get recycled to hell due to that difficulty too. If some tool breaks, you feed its metal into the next batch being smelted.
Bronze even more so. People actually started using iron because it was cheaper and more widely available, albeit of lower quality for tools and weapons.
@@pauljs75 There's a limit to recycling metals, like gross iron. There's always a loss, and primitive techniques were just not efficient. Nothing was discarded, but you still needed an influx over time.
Remember to turn on captions to see a description of what's happening. Experimenting with brick furnaces this time because they're quicker and easier to build than the in situ clay piled ones. They're also more portable, the height is easily adjusted (adding/subtracting bricks) and the bricks can be stored elsewhere when the furnace is not in use if space is an issue.
im curious now about the possibility of making a brick charcoal kiln! i know youve made the classic mud mound type before but that was before you had solidified (ha!) your brickmaking technique; you mention the open pit charcoal technique as good for producing non-dusty charcoal, but how much of that is due to the dousing with water at the end, and could a similar technique be applied to alternative methods of charcoal generation?
Thanks for posting this video! I love the captions, such a good idea. I know you get this a lot, but you're my favorite youtuber and it always makes my week when you post a new video. I love your metalworking exploring and use of things that are very common in otherwise relatively boring landscapes with the Iron bacteria!
I remember watching your videos a couple years ago without knowing this and I was so confused until I accidentally turned them on and got a whole new world

Nice to see you active again on UA-cam, enjoy watching your shows. What iron tool could you make that would improve everything else you've done to date? Axe? Knife? Other?
I'm looking forward to this guy steadily advancing his tech, using the tech he has already created. Eventually he will have to rename his channel to "Modern Technology", and then things get real interesting when he needs to rename to "Future Technology"
" Building a nuclear fission reactor "
He should call it Back to the Future technology.
If he lands on the moon next week he will still be doing old technology. His channel is about "ancient technology" don't be a retard.
looking forward to his semiconductors from sand video

from my research into iron smelting, i believe that you need to scale up your process into a larger furnace with a larger smelt over all. you have the prills, but if you had enough they would congeal into one(ish) piece. also: try adding some limestone dust ir ash to your ore powder, it makes the slag melt faster letting the iron fuze together more
Hope John sees this advice!
I seem to remember him saying he didn't have any limestone on his property, but it has been over a year since i saw his comments
@@chadasmr8304 Just because he doesn't have limestone doesn't mean he can't make his own lime.
@@TheZarric yeah just burn some bone or shell.
Wait, didn't he already make a lime if I'm not wrong
@@chadasmr8304 he did make lime powder before, which is the same thing, from a different source

I'm so happy that he takes his time with these videos. The amount of work is insane, but he can totally make a living from his pattern an a few million views per video. The fact that this get's us one of these absolute gems a video every other month is just beautiful
I think he has said he has a day job. This is a hobby and he only started making videos to demonstrate what he describes in his blog. He did recently turn it into a book, though. So that cool.
I mean he’s been doing this for years so he has already made a living from it lol
Stop being so nosy, it's kind of creepy
And he hasn't succumb to the fad content churning trend either. It's just a nice honest hobby he enjoys and gets good side money from.

I just realized this channel has been going for 7 years. This guy is so OG that he outlived everybody that tried to copy him and is still going strong.
Please keep it going man, these videos are great and always make me want to go out to the bush and mess around!
And he keeps it real. Some of the copycats do absolutely stupid projects that are nothing more than destructive to the environment for temporary enjoyment and video content.
I've seen videos of people making in-ground "water park" slides and pools, and structures that are certainly going to flood and/or fall apart in short time. Primitive technology is much more akin to surviving and being in harmony with nature.
Is also because he's one of the few that actually sticks to the principle and does it out of his own curiosity how things might've worked when we had nothing to do things with
Yep - this is what it is to be an original. Whether an artist, a builder, an athlete - the best ones only care about exploring their talent to please themselves. He's an inspiration.
7 years holy guacamol. That long, feeling old now.
legit, he’s even that good man’s skipped the bronze age
Very very few UA-cam channels I literally drop everything to watch a new video but this channel has had my undivided attention for the better part of six years. It’s a pleasure watching him work
Fantastic work as always! Glad to see you trying new things suggested by viewers.
Having studied metallurgy for Welding, I would recommend making the furnace taller to increase the time the iron spends in the reducing atmosphere. It might also be detrimental to cool the furnace with water. Allowing the molten iron droplets more time to coalesce and ensuring your prills aren't made brittle/more likely to shatter from the shock in temperature.
Another thing that might be worth trying is piling the left over slag in the bottom of the furnace, preferably in an inverted cone acting as a makeshift crucible. After enough firings, you could recover quite a bit more out of the slag alone. My last advice would be to research any sort of naturally occurring fluxes you could add to either your ore powder or the finished prills when smelting together.
I can't wait to see what you end up accomplishing with your growing iron stash!
Very excited to see what you'll use that hard-earned iron for. Love your videos

That's awesome. I started it because of him, too, you could say. Watched a lot of Fritz Meinecke, a German bushcrafter, after i developed this interest, but the beginning was with these videos from primitive technology 😊
I've watched ALOT of UA-cam videos over the years and yet nothing compares to this man and his skills.
This dude has the the crafting skills of minecraft steve, he can smelt iron in a stone furnace without any major problems and make a whole house out of everything around him
Steve is more like a god teaching a mortal here. Steve can use his bare hands to reshape and sharpen diamonds, punch trees down in less than a minute, and carry more than an entire train.
This man can do the things steve does, but must take the longer route.

After watching this new series on iron smelting, I’ve been looking at iron utensils and objects around my house with a lot more respect
It's funny how people don't appreciate where things come from....city people think milk comes from bottles and water comes from taps and have zero appreciation for the effort and energy required to produce things...thus the city people are the "greenies" who just want to turn stuff off having absolutely no idea of how things actually are produced and what affect it will have.
This is probably the most important comment in the whole video. So much technology and human ingenuity goes by people who never stop to think where it all started and how we got here. Most would probably go from "There were cavemen who invented fire" to "I can make TikToks" with nothing in between, except maybe a medieval movie. I find myself constantly in awe with how far we've come as a species and where we might go in the future. Sends chills down my spine it does!
We take most technology for granted. Now iron is made in vast quantities because of how efficient weve gotten and the amount of ore we can extract from the earth. It always starts out slow but as we gain technology, we gain the ability to do what we did before better/faster. farming, killing, housing, calculating, and so much more has come so far with technolgy. And when I say technology, I dont mean electronics, I mean nearly anything as at some point, it was revolutionary. The fork? the spade? everything.
On a related note, people often fail to realize that complex things like ships or cellphone networks are NOT the product of one brain.
I've heard SO many people say "how could anyone do that?", totally missing the fact that almost everything we have is a small improvement on something else.
The explanation of "how to build a moon rocket" really starts with "break a rock with another rock, then your buddy decides he can do it better".
This guy is one of if not the only one that really does things step by step, without tools or a big team behind...
This is educational and if he gather people to make a documentary about this, i am sure lots of people will like it
the only REAL primitive building channel
This is probably the best fire footage I've ever seen in your videos, John. That purple flame is beautiful. And that furnace in the last sequence of dousing at 10:47 looks like a rocket and a volcano had a baby! Definitely worth watching that bit at half speed. Also interesting that you didn't pack mud around the sticks when making charcoal like you have previously. Did you determine that step wasn't necessary to get the charcoal quality and quantity you need?
I think it's just mich quicker and easier to do for these small amounts. The historic charcoal mounds were sometimes multiple meters wide / tall. There it makes sense to cover.
Adding the mud takes more time, building and removing. everything about efficiency and time, semi-same results. I think he "talked" about that in one of the previous videos
The purple isn't visible in real life sadly
only a few more episodes until john has reusable space rockets
@@coro8933 lol wym, yes it is
5:00 - The centrifugal blower never gets old for me. The underlying mechanism is surprising, its role is important, the design is simple, and the resulting pulsating "roar" in use is almost anachronistically industrial, like the sound of a coal-powered train warming up, but in the Bronze Age. A bridge between the primitive and the modern.
This channel is incredible. It’s like being given a portal to the past.
If you use the old meaning of "industrial", it really _is_ one of the sounds of industry.
Cavepunk
It would be amazing to me to see him utilize flywheels for some of these tools, to avoid directional changes being needed. Though he'd also have to make "belts" out of leather or cordage then. Just that having a "bike" to let him spin up a flywheel, an act as a power system for some of his tasks sounds like it could be beneficial. Leg muscles are significantly stronger than arms, and tire less easily.
I feel like pulleys acting as gears could accomplish quite a lot for advancing how automatic some of this stuff is going like for the ore crushing, or for the slag crushing, both steps could benefit from a bike-powered grinder or crusher.

Mate, I just have to say it again, it is SO SO SO VERY GOOD to have you back on YT. Keep up the excellent work.
10:47 - Fun fact, the water is what's actually "burning" here. Charcoal is a reducing agent, and can reduce hot steam into hydrogen and carbon monoxide, which then ignites due to the high temperatures inside the furnace. That's why the flames went crazy when the water was thrown into the furnace. This reaction only happens at temperatures above 1000°C, so the furnace was at least that hot. This mix of hydrogen and carbon monoxide is called "water gas".
The only original primitive tech channel....
Two things to consider, the first is a taller bloomery furnace, the second is you should reuse your slag to get a bigger puddle going sooner so the prills have more time to fuse together. You could also consider adding limestone to make the slag more fluid.
@@Galanchris Does the high surface area of using powdered ore not mean that there is a risk of the resultant metallic iron burning? I know the opposite is happening and the iron oxide is being reduced, and oxygen is limited, but there is air being pumped in and some of it might be reaching the metal as well as the charcoal. Or is the iron forming as the prills, rather than forming prills after becoming iron (if you see what I mean). Ironworks don't use powdered ore I don't think.
Awesome information, I was wondering if there would be any use for the slag that's left over from this process
@@demetrimanasses6240 in a bloomery furnace the iron ore is crushed and powdered too, so i guess it kinda reacts the same way
also finding a way to actually consolidate the iron into a usable billet
Also, making a crucible to keep it from mixing with charcoal, and getting less slag.
I LOVE how refined your processes are!
The new simple charcoal method, the smaller furnace, the leeched ore.
Fantastic.

@@alf3071 nah he's gonna have enough pig iron for that
I love that he keeps building new furnaces every time instead of just reusing the old ones. You really don't miss anything with these videos!
I remember the first time he showed how to make charcoal with all that enclosed mud container and stuffs. Look at him now, he just need a hole and piece of woods!
I love how he avoids saying iron balls at every opportunity. I would find it quite rude otherwise.
This channel is the original PrimitiveTechnology and it is the one worth watching...

Cannot over exaggerate how real this channel feels. Actual techniques applied to a real environment.
Having a semblance of an idea how to make stuff like this can be useful.
Best Minecraft "Let's Play" ever. 10/10 would watch again.
I love seeing your previous developments like pots, bricks and the blower used to accelerate new projects. Insane how much ingenuity, knowledge and sheer effort goes into every inch of technological progress. But at least with every new tool, it gets a bit easier. Excited to see what this iron will be used for.
probably won't be very much of it, it might be used for a blade or an arrowhead or something like that
@@Eralen00 In one of his older videos I think I remember him taking the prills & trying to melt them down into a knife mold. I can't remember how well the blade came out though.

Have you tried collecting the wrought iron prills and smelting them in a crucible to get more pure iron? It would probably be a ton of work, but I'm curious to see if that's possible with just the stuff you can find at your site.
Opposite question: seeing how much slag is produced for each piece of iron, I wonder what that might be good for. Possible to extract any other metals? Or since a lot of it should be various silicates, maybe it could be ground up and used to glaze the pottery?
He took the iron prills from a similar process before and made a mold and made a knife from the iron prills. Not really a crucible but kinda in the same line. Here is link to it if you haven't seen it yet ua-cam.com/video/dhW4XFGQB4o/v-deo.html
@@xcreeseseater38 Yeah, I did see that one. Granted, it was after I made this comment lol. But that was more of a casting, what I mean is using things like lime to remove phosphorus and flux to promote a more liquid product so it is mixed uniformly.
Honestly though, it would be a tremendous amount of work for probably not that much payoff? Maybe he could make that axe he talked about in the casting video or something though.
@@Nannars My guess is, the issue there would be whether he can get his furnace hot enough to melt the iron in a crucible.
It seems this technique of having it all mixed in with the coals and having to pick the prills out later is because direct contact is getting it just *barely* hot enough for that, and the furnace is just a little short of being able to get the inside of a crucible to reach the same temperature. This would be why his knife is a little lumpy -- the melting was incomplete. On the other hand, if he's that close already, maybe it's not out of reach.
(I'm totally guessing all of this, but it makes sense to me.)
@@voidstarq The issue is in fact, getting temperatures hot enough to melt iron. A bloomery furnace (which is what he's using here, just at a small scale) doesn't actually melt the iron. It melts the rocky ore the iron is trapped in because stone actually has a lower melting point than iron, and the iron coalesces into those beads. With more pure ore you'd get larger chunks of iron known as a bloom. This is where the term bloomery furnace comes from. You'd need a coal, or better yet a coke furnace, to actually melt iron.
This dude is speedrunning civilization, he's on record pace to achieve industrialization.

After watching your process makes me appreciate artifacts from Iron Age. Truly appreciate all your work. Thank You
This is the slowest Minecraft playthrough I have ever had the pleasure of watching
I really like the look of that method of making charcoal. Some of the other methods I’ve seen you do seem very labor intensive. But this method looks like something I could do myself relatively easily. Super cool
For my blacksmithing and bbq I go around and ask everyone if I can clean their fireplaces for them for free everyone looks at me weird until I say my payment is the charcoal inside it I get heaps this way because everyone tends to burn hardwood in it I have about 20 people I clean out for once a week and I have 44gallon drums full of it
I make charcoal on my homestead using a similar method, except generally I do it in a 55g metal drum. Fill the whole drum up with wood, light it from the top and douse it when it burns down to coals. It goes to make biochar for the garden and hardwood charcoal for the grill. If I had more time I'd probably play with some smithing but never gotten into it.
If you are in Europe, you are a visionaire
Thanks for you real authentic work, I hate that others are faking their work
You have fulfilled one of my greatest expectations for this series. Thank you for all your hard work
I like how he just speeds up trying other furnace shapes to just couple of minutes, while it lasted 10hrs or more propably and took so much effort.
This keeps getting more and more efficient. I remember the first time you smelted iron it was so little.
He is the most primitive and true survivor, starting completely unpaid and without equipment!
He can survive and live in any environment. That is worthy of respect.

Stone Age to Iron Age, with just the sweat of his brow and the labor of his back.
Brilliant.
Cool! With my limited experience I would still like to propose two things. 1. I think you have a too short furnace. You need at least 50 cm of height (from tuyere to top), so the ore has a chance to reduce on the way down. If I remember right the ore grains needs about 1h per mm thickness in a reducing zone 2. You should roast the ore before smelting to drive off moisture (which cools the furnace) and also make it more porous so it can accept the CO gass. It's also very important to have dry charcoal so extinguishing with water may not be the best thing to do. Just some thoughts.
Very astute observations! I hope he sees this
Indeed he says the charcoal is not as dusty as other methods, maybe that's becasue it's not dry?
Roasting is also a good idea bc you can burn all the organics in iron bacteria so it would also purify the ore
Torbjörn Åhman is an amazing blacksmith and builder. If you haven't seen his channel I'd highly recommend. This video had me looking for iron algae in/near the streams in my area. Haven't found any yet.
I also have limited experience with smelting ore, but everyone I’ve ever seen do it (Japanese tomahagane, African tribal smelting, etc) makes a hole at the bottom to drain the slag, causing the iron to congeal together into a “bloom”. Quenching it at all seems like a mistake and is the reason you’re picking prills out instead of refining a homogeneous ball of iron. I might be wrong tho 🤔
You went above and beyond doing this 3 times with different configuration. Great content as always!
It's nuts watching this for the first time. Seeing the iron ore balls at the start and thinking, "Oh yeah, that's a lot of iron" only to see the absolutely miniscule amount at the end. Goes to show the importance of more advanced mining and refining that gets l developed later down the line. It had to start somewhere.
Question, have you considered using a round furnace with an offset tuyere to create a spiral flame? When I did industry to build furnaces, this was one of the things that was stressed in order to get an even and efficient flame.
Interesting idea - presumably though that would only work if you were using a crucible type setup.. I have thought though about this - would it be more efficient to have a crucible/pot in the center with just the iron ore in it, then the fire around it. That way you keep the iro ore seperate from the fire. Granted I expect there could be thermal reasons why this wouldn't work and I'm a lay man so know nothing but still, I wonder if it would be worth a shot...
@@andyjackson3663 Your take on the circular draft being for use with a crucible is correct. It would normally be fired by gas or oil. It is what you see most home foundries use.
A cupola is usually fired with charcoal, coal or coke, and the metal or ore layered directly in with the fuel. The tuyeres are then normally arranged around the bottom pointed straight inwards. 2-3 tuyeres and usually a sight port. This goes for small hand fed cupolas as well as giant blast furnaces.
I did a casting class at the Metal Arts school at the Sloss furnace in Birminghan, AL. It was a small coke-fired cupola with maybe 1 ton capacity? It was standing about 30' from the 3 story high blast furnace that was used at Sloss many years ago.
@@andyjackson3663 i think the iron ore needs the charcoal to get the iron out of the iron oxide
Respectfully your a nerd
That works when you use gas as fuel. Coal needs to be blasted directly with air instead, according to my imagination

He's also one of the only ones that do it legit XD
@@sabata2 exactly, all the other video on YT were hoax by mostly southeast asian.
@@sabata2 THE only one as far as I know of.
@@sabata2 That makes videos*
Thank goodness he dropped another banger. My mental health was declining before this
Something I feel like you are missing and would be a massive force multiplier for your efforts specifically, is a pottery spinning wheel. It seems totally up your alley as well!
I always like it when UA-camrs do their best to protect their lungs. People! Please take lung safety seriously!
Breathing in wood dust causes cancer, so even when sanding wood, wear a mask
@Not gonna lie Let me guess, it one of those cooking videos
Really really cool seeing you getting more and more advanced with the iron, but at the same time the trebuchet video was amazing too. Keep it up, I hope you're having as much fun doing this as we all do watching.
Yeah I wanna see more videos like the trebuchet. We should provide him with some good ideas.
It's crazy to see after growing up watching him for almost 7 years now how much Older he looks physically, but it's great to see him still out here doing this
*Спасибо тебе Автор за то что ты есть! Очень умиротворяющие видео.*
You should post a 1h long silent video of this smelting process. So relaxing and calming to watch.
Then you’d see him hock up the electric blower😂
Probably not though. This guy seems the real deal
Calming smelting sounds 1 hour
Yeah i'd put that on, don't remove the audio tho!
I wanna hear the rythmic whooshing of the forge blower!
True. I was already beginning to doze off because of watching this. Not because I was bored, but because it was just really nice seeing him work.
I would really enjoy that
Make a clip like this and loop it ua-cam.com/users/clipUgkx1NZpOha_JVMqhARE4J-pA9_GLkAAaYCG
Would love to have a counter on the side which shows how many real-time hours are the equivalent to the amount of footage we've seen so far, to see just how much work goes into the videos! I imagine it's a ton.
yea absolutely agree. that'd be awesome!
"Ton" is not a metric for time.
@@JackFate76 it's a turn of phrase you doof. Also it wasn't being used as a metric of time but a metric of work done.
@@JackFate76 Lol
@dontkillmejay
For reference, some of his older videos took months to finish.
you are the original guy that made videos like this. the others that came up after you just make buildings without really understanding what primitive life is. or what it must have been like before advances in technology became available. they all just want to make pretty stuff.
This is fantastic. There’s no way any of the copycat imitation channels would put in the effort needed to make this kind of project. It really sets this channel apart
Your videos bring me such joy and peace. I had a pretty rough day, I work insurance in South FL and it's been hard this last week with Hurricane Ian.
This was a small moment of joy. The sounds of nature, the rushing stirs of a fire... It brought me back down to earth.
Thank you brother
Alex, you certainly would have your work cut out for you at the moment following the Hurricane. You are entitled to ask for help from the rest of your organisation as you are right in the eye of the damage zone, so don't take it all on yourself.

Be as merciful in your assessments as you can be. People are hurting bad.
Also, thank you for doing a necessary but thankless job.
@@TheInfinitySystem - People who build their house in a flood zone deserve no sympathy. They knew this was coming.
@@person800 those are the people that insurance doesn’t cover… fema does. Ie the government.
@@person800 you’re obviously trolling. No one is actually that cruel or stupid.
I never thought a circular furnace could bring me such joy. The effort you put into these videos is insane!
I know, right? It's so pleasant.
He's making millions of dollars so why wouldn't he
My man advanced to the iron age. Lets goo
I’m so excited for the potential of future metal working videos.
I remember asking you years ago why you never tried to make metal before and you responded with a big list of reasons why it would be incredibly difficult, I'm glad to see you have taken on the challenge now! It's incredibly interesting to see how you use the environment to smash through your limitations 💪👑
Can you find that list :)?
I love this channel! It’s one of the very few channels that I have notifications turned on for. Whenever primitive technology post a new video, I drop whatever I’m doing and watch it.
@don't be surprised this one too
ua-cam.com/video/hr8xus6xi_8/v-deo.html
You are probably the only legit primitive channel.
My favorite channel to chillax and learn something interesting. If they made a Bob Ross award you've definitely earned a few.
Sine hello
2:57 I like how he covers his foot with hand. He deals with extremely hot fire very often without advanced clothing and probably got burned many times.
I can't express the sheer excitement and joy I get when a notification for your uploads pops up. I need to always sit down and make time to sit and enjoy your video and not just listen to it in passing. :)
Как всегда, на высоте! Жаль что видео долго выходят
Imagine hiking through the woods and stumbling into this shirtless fella using ancient tools like he's recreating life in 5000BCE.
When the Ud Reaa moment kicks in.
Haven’t seen ur vids in years. So glad you’re back and making content again. You’re a pioneer in this genre! You started the wave!
These videos could be 6 hours long and I'd watch every second. Some of the best, most unique content YT has.
Seeing as you now have lots of access to charcoal, I think it would be really cool to see an offshoot episode from the quest towards the iron age (like the trebuchet) to try and make some art supplies like paints and paper. It would give you a good way to pass the time while waiting for things to finish drying or burning, and could add a lot of livelihood to the shelters.
Ngl making paper primitively sounds very interesting
@@poorlydigitallydrawngigachad I have a similar interest in primitive tech and have looked into it, but never tried it. You have to find a fibrous plant and process it into shreds, then wet it to flatten it into a sheet to shape it and dry it in the sun. It's not hard, just might be difficult to make a lot of if the local ecosystem isn't meant for it. hard tablets are another option if that's the case.
In terms of the art tools themselves, charcoal could easily be split into thinner shards to be used as pencils, and could even be wrapped with something to prevent staining the hands. Paints are harder to be specific about, but are weirdly easy to produce despite that, since a lot of things (especially fruits and earthy materials) stain really easily. I think it would be cool if he could find a way to produce orange out of that iron-based bacteria from the streams, or mash down super green leaves to use their chlorophyll. The possibilities are endless.
The other interesting things that could come from this other than 2D art are things like pottery or painted sculptures, which would liven up the environment a lot. He could also use the materials to liven up the designs of parts of his shelter, if water didn't reach those parts easily. Considering his recent iron knife development, carving would could even be an option. I hope he sees these ideas and considers them, because art was a major part of the period of history this technology was prevalent in.
There's some pretty neat ways you can make some primitive art. Red ochre was very commonly used across the world for face paint, rock art, etc. Unfortunately, making paper is kind of a waste of time because rocks are literally everywhere and paper takes time and labor to make. It would definitely be a good one off video though
@@psychopiper8224 That's occurred to me too. It would not be hard to sculpt decorative patterns into the outside of his pots; this might even make holding them easier. (Most primitively, by just scratching them on with a stick; later, any number of pattern transfer tools.) What kind of paints would be practical I can't guess, as a lot of that is very specific to the local plants.
he's now evolving into the Golden Egyptian Period.
I like the way everything is generally tidy. Doing such work is a serious activity and it naturally creates a sense of discipline.
If you want to increase the airflow of the furnace then move your furnace blower a little bit back from the funnel intake. The air from the furnace blower will then pull in air from its surrounding, resulting in more total air going into the furnace. Will make it easier to get the furnace even hotter with equal or less effort!
Yeah! Utilizing that bernoulli effect!
Incredible how much work he puts in to extract a bit of iron. Very impressive!
There's a ton more work in his videos compared to people that are just doing "try on hauls" or item "reviews" or anything else basic like that. Quite literally weeks of work for each video. There's all the literature that he combs through in books and on the web, then the trial and error of working out how to replicate in a way the how it might have been done in more primitive times before the industrial era began, recording, editing etc. There is so much work that goes into making just one of his videos. Not surprising that he has well over 10m subscribers.
man i love iron age technology, and its amazing how youre needing to figure out and learn to do jobs that were split between multiple professions
This guy is giving knowledge to the World. Thank You
the only legit primitive technology channel and the first
I look forward to your videos probably more than anything else I watch here on UA-cam. Thank you for coming back and making fantastic content.
There's no question, these are the videos I look forward to the most. The moment I saw a new video was posted, everything else stopped and it was time to watch.
Same for me. Best content on UA-cam, bar none.
the OG of primitive bush craft! I recently watched a video from another channel describing how primitive technology type channels fake their videos, but, this channel was deemed legitimate by so many people. this was the first channel of its category I ever watched & I was instantly hooked. KEEP UP THE GOOD WORK MY MAN!
This channel becoming popular is the reason fakes even existed.
Grrrrr, those fake channels really annoy me. I don't even watch them anymore, they don't deserve the views.
I am in awe as usual. Massive respect.
Primitive and Sam O'nella coming back so close together has to be a sign. (I'm aware prim has been back for a little bit but still)
It's awesome to see you often! No music, no voice, only subtitles and you.
This remind me old youtube times. Thanks
For the first time on this video I kept getting a pop up in the top right corner for the video description while fullscreen. I keep clicking the X and it keeps coming back. Kinda ruins the whole point of me watching his videos. Takes me right back out of it.
From Stone Age to Iron Age. Guy’s levelling up.
Forget Copper and Bronze.
7 fricken years and still watching one of these are great
so much work for so little iron, you are definitely a man of patience
