About This Video:
I made charcoal in a clay pot by putting wood in it and heat the pot externally effectively making it like a retort. Previous methods of charcoal making directly heat the wood by burning a portion of it to create the charcoal. But this method applies the heat indirectly to the wood with it completely sealed off from oxygen. The wood successfully turns to charcoal on a small scale but fails to scale up due to the larger pot cracking during the firing and letting air in which burns the wood to ash. The theory is sound but more work needs to be done on the pot to stop it from cracking.
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.

The first attempt on a small scale was promising and made good charcoal. But the second experiment failed catastrophically as the method failed to scale up due to the large pot breaking. I've fired large pots before but it was in a solid wall kiln that probably let in less cold air. It still made some charcoal but the mound method is still the better choice as it produces charcoal on scale, or the pit method for quicker low quality charcoal.
Very interesting to see this process. It proves that charcoal is made in truly chemical process of incomplete combustion. Nice from you to share this experiment even if it didn't work out completely :D
maybe I missed something but I was wondering how come you didn't fire the pot first before trying to make charcoal with it.
I'd assume that the wood off gassing would increase the pressure in the vessel (probably what the hole you left was for) but not really sure. It feels like firing the pot first would have been better.
Another reason might be due to the thermal stress from the gap at the top. Every time I've ever seen charcoal made in this way, be it with crockery or with a metal bin, the opening has always been on the underside, similar to the mound method.
i really appreciate you uploading videos where something doesnt work as intended or fails, your stuff is always great to watch. cant wait for the next one mate.
How much extra work was making a bigger pot? Was really cool to see and I would love to see you make the big pots work. Potentially useful for batch processing other products too.
You made charcoal in a closed pot because you need a reliable heat source.
I made charcoal in a closed pot because I forgot to turn off the stove.
We are not the same.
😄👍
😂
Was it a good quality?
I once made charcoal in the pot. Mom was not impressed by it in the slightest when she came home from work. I tried my best to scrub the pot but alas. To anyone who wants to try: soup makes bad charcoal.
@@AlleonoriCat when I was... probably nine... I, for whatever reason, closed kitchen door while playing PC and forgot buckwheat in a pan on small fire for approx six hours. That was best charcoal I ever seen - glossy anthracite. Pan was bent though.
I'm so glad you show everything that doesn't work and not just show everything working perfectly. It shows how much work this actually is and how impressive our forefathers were for figuring it all out.
The little dose of primitive technology every now and then keeps me from deleting my youtube app. There's just nothing comparable.
Have you tried out doing the thing he’s doing though? Mostly kidding bc I know life gets in the way and it seems like it would be much much more difficult to do than to watch. I sure as hell haven’t. But who’s stopping us? 😮
everything stops when a primitive technology video is uploaded
It's a big F if I don't watch it in the first hours. so we all get a W today!
Don't forget to turn on subtitles / closed captioning!!! He uses those to tell everyone what he is doing.
@@tulipalll 💯💯 REQUIRED.
yes, indeed
One of two channels that I have the bell on for!
Often imitated... NEVER duplicated.
Best channel on CZcams.
The original is always the best.
Literally skill issue.
This channel and Escape to Rural France- my two favorite channels.
You a World of Outlaws fan too?
meh he dropped of years ago and just cant hold to the same standard as what he used to it literally just making charcoal that's all he does now...... where as primitive skills yeah its a copy but the guy has a whole farm going on and actually has metal tools.
Everything he does, including making fire, is incongruous with the idea that we are viewing this through high-tech cameras on site. His videos are so entrancing that they just keep you coming back for more.
Imagine we are viewing him as a spirit guide would - congruity restored.
You videos never get old. I simple love that it does not shy away from showing the failures too.
"Multiple cracks appeared and luminous flames now shoot out of them" might be the most relatable sentence I've ever read.
Very relatable. That's how a party at my place ended up after an evening of spicy Mexican food.
I think it will not beat "slowly blow the smoking punk", which until now is my favorite, but yeah, very relatable sentence indeed.
Seeing that made me go "yeah of course people saw this and thought that wood had ghosts or spirits or whatever"
Biblically accurate charcoal making
i am literally in the comments section for that very caption. 😁
I'm always happy when the episode takes a moment to feature a special guest animal. Primitive Technology knows what's really important.
I would love to see a non-standard video just exploring the local geography, plants, animals, etc. I've always been curious where all the structures are in relation to each other.
Don't think it was a mouse, though, looked like a dunnart or something similar to me.
I love it that after so many years I still find it very exciting and soothing at the same time when he ignites a fire with friction. It also shows that all the advancements he made still requires the one key element done the same way!
he has repeatedly shown unedited fire-by-friction to millions of people that have never seen it, who come from unbroken lines of ancestors who could all do it
I actually really enjoy the failures, its so nice that you just post them as a lesson learned rather than an actual mistake. Learn move on, do better, repeat. Good life lesson right there. Bravo
Same, I learned to not go too big and make your clay thicker for something big. That was too fragile to fire without a professional oven.
One thing the imitators lack, even the good ones, is the sense of scholarship. John is partly replicating ancient techniques, and partly exploring them in order to understand them. All of the various attempts to turn his poor ore into iron have been about exploring the possibilities.
It would be interesting to know the Nationality of all these commenters eager to use the word "failure". I assume it is from a country with a low I.Q. and/or an insular outlook.
If the man wants charcoal, he can buy 12 Kgs at his local Bunnings, for A$ 39.95.
People from a Rationalist Society, understand that he makes interesting popular videos for a living.
And has NEVER, will NEVER "fail".
It takes very thick skin to sink that much time into a project, and to see the inevitable failures as lessons and recycling opportunities.
You wouldn't learn much if you don't make mistakes .
Every video feels like a newly unlocked portion of a tech tree
it's the small tutorial video showcasing what you can do before you pick the perk
Don't forget to turn on subtitles / closed captioning!!! He uses those to tell everyone what he is doing.
@@tulipalll NOW YOU TELL ME
😂
@@satormus8263 Think of all the videos you can watch again, reading the subtitles!
During WWII, many people converted car and truck engines to run on wood gas. Very potent, as shown in this video.
Great stuff as always. Thanks for sharing it with us.
I love how even and symmetrical all of the stuff he builds is, even the pit where the clay was collected. I dug a fire pit in my backyard and it turned out so crooked I couldn't believe it.
The evenness and symmetry of the giant pot!
Don't forget to turn on subtitles / closed captioning!!! He uses those to tell everyone what he is doing.
I like watching it without subtitles, it's more engrossing and most of what he's doing is pretty clear.
Thank you, I didn't know that and it made the video more enjoyable the second time around!
@huehuecoyotl2 to each their own! I know a lot of people prefer no subtitles, but every time I post it, it is new for someone who is ecstatic that they are Available, so I keep up the reminders.
@psicologamarcelacollado5863 I'm so glad! He's been doing this, I believe, since the beginning, so it's a great opportunity to rewatch a lot of his older videos! He explains a lot of things in great detail, and I learned a lot more when I went back and watched them all again after finding out about the captions.
@@tulipalll definitely. A lot of people don't realize there even are subtitles. Thanks for letting them know. I urge people to watch it first without, then with. You get twice the entertainment.
Humbled by failure, like everyone is. Love to see it put on display.
Tbh, I think that's what makes these videos, because it really shows just how difficult this is.
Like, there were at least four updates on the different fans he was building for his kiln blower.
Humbled means something slightly different in English, friend.
Trying is a necessary component to success.
I wouldn't call it failure, but experimentation. Even if he didn't end up with a new way to produce charcoal, he gathered data.
Not a failure. Look at all the material he made to mix into the next project.
Каждый раз поражаюсь, как он умудряется уместить столько работы в десятиминутное видео, от которого невозможно оторваться! Обалденный мужик!
Полностью с вами согласен !
Ну ему некуда спешить. Сначала снял то что нужно, потом оставил то что будет логично понятно и смонтировал

Меня только вгоняет в грусть, что он всегда один, молчит и без женщины...
It is almost decade since I start to watch this channel and in those years this guy managed several thousands of years of progress. From mud hat to brick house, from handmashed pottery to ten gallon pot. From stick tool to iron. It is amazing journey and I am glad I can watch it happen.
watching you pour that clay onto the grog and then fold it all together was so satisfying
Interesting how much it immediately looked like dough.
Like a giant thick tortilla
As a kid, I spent a lot of time in Southern Missouri Norther Arkansas where a lot of charcoal was made. I remember seeing setups as small as your big pot up to giant metal kilns the size of connex containers. I actually mad a few pots and tried it with a few of my cousins. What my uncle taught me was to let the clay vessel dry for almost a week before using a low heat fire to further dry it. He said it could take 10 days to 2 weeks to fully dry the clay, then it was fired in one of the big kilns to fuse it or they would place several in a large bonfire. Also in addition to grog, he had us add some sand to our clay mix. I know I only used 2 handfuls of washed fine river sand to a pot about the size of your small one. That was a childs hand, I was only 8 at the time. I would think it would be 1 adult handful.
What was the charcoal made for?
@MrCh0o for sale. A lot of charcoal is made in Southern Missouri northern Arkansas. I know some of it was sold to a distillery yet a lot was also sold to blacksmiths and also for people to use for cooking.
This Primitive channel expands my vocabulary - this time it's "levigation". The irony! (And sometimes the iron.)
One thing I love about this channel is how he never hides his failures. He always shows everything he does, whether or not it works, and is willing to test new ways of doing things.
he doesnt show everything but there has to be some success to the initial theory
Traditionally, fires in Japanese houses did not have chimneys, as the rising smoke helped evict bugs and criiters from the thatched rooves.
It works on 'mice.' (Quotes included because it's not technically a mouse but a southern hemisphere marsupial that's basically a mouse to non-biologists.)
Primitive Tech videos are the only quiet time I get as an adult
That doesn't make sense
7:54 we went camping this weekend and we struggled for 30 mins to light fire with match sticks and a cigarette lighter, just because we forgot to carry starter fluid - and this guy just flexes with 2 twigs.
Last winter I got into sitting outside at night with a little fire in a big way. It was soothing and cozy. Holy hell can making a fire be hard, even with a lighter. You really have to give it effort.
The trick is to get very small kindling (fibrous materials, leaves, very thin twigs broken up) and lighting that, and progressively adding larger and larger pieces of fuel. You never want to add something so big it'll absorb all the energy of the fire you've currently got going without burning. It takes time and patience!
@@static_motion I second this. And also don't underestimate how fast the small stuff burns. Keep adding more until you get to the big stuff otherwise it'll burn out.
Do the "hut" method.
Make a floor out of some medium pieces. Then get some Ys made of twigs and make a little hut on top of the floor, you know, like an indian hut. Leave a "door" open. Then get some kindling, like dry leaves, paper, very small twigs and the sort and fill the hut with it. Light the kindling and presto, easy fire.
Keep adding stuff because the hut burns rather quickly. No need for starter fluid.
It's the method John uses. Of course, he uses two sticks. We have to make do with lighters and matches.
@@static_motion I save dryer lint, to assist with starting campfires.
Genuinely appreciate that you're showing failures along with successes. Really interesting video!
I watch these videos with my young daughters. It is really nice to be able to show them that even "the builder" (as we call you) will try new things and they don't always work.
I am so glad a friend shared this channel with me years ago.
I'm buying a house and a bit of land in an area with heavily clay laden soil, and I plan on making my own levigation trench to make stuff out of clay, just for fun.
Thank you, for that knowledge.
hell ye
John re-invented the gas stove! 🤗
Also, RIP big pot 06:20 - 11:00 🙏
Was so sad the big pot ended up in the grog pile, such an anticlimax end
RIP big pot, May you forever store items in a heavenly warehouse
Achei que iria explodir 😅
I love that you are back making videos.
The chillest ambiance mixed with genuine curiosity is the best.
There’s something so grounding and redeeming about seeing even a “catastrophic failure” go into the grog heap to later be used in bigger and grander projects.
•
Love this content! Keep up the great work!
I known your failures probably aren't your favorite experiences but knowing why one method was so popular when a "better" method exists is so cool.
I appreciate that we also get to see the failures, which makes this all the more genuine.
THE REAL ONE has returned!! I love when the REAL GOAT of the Primitive Technology videos return with new lessons :3
Do not forget to turn the subtitles to see the full explanation of what he is doing.
@2:45 thank you for laying out the result of the first firing so that we were able to see the proportion of good versus undercooked. That attention to detail is very much appreciated.
I think the most important thing I've learned from your videos is there is no need to rush when starting a fire. I think every TV show and CZcamsr, other than you, I've seen has made it seem like it was a difficult process that you had to rush once you see smoke. Watching you, you are calm and relaxed about it, no need to panic, no need to rush.
For the making of charcoal would stacking multiple smaller pots, like the first one, provide the better charcoal without the hazards of the large pot?
Methanol acetic acid and tar can be obtained from deciduous trees
@@user-yy2hb9iz1t Australia doesn't have many deciduous trees, our trees keep and drop leaves year round.
@@phaunaThen what does he make charcoal out of? Made of hardwood trees.
@@user-yy2hb9iz1t turn on captions.
Not all charcoal is made of hardwood.
He used olive
@@DH-xw6jpolive is not an Australian tree species.
0:51 I think that's an antechinus, a little carnivorous marsupial, not a mouse!
yes a slightly longer nose and a tuft of fur on the end of the tail. They like to nibble on hard plastic which is a pain when you go to get your 25 liter water jerry and they have chewed out the bung.
Very Australian animal. The males get too excited when it is mating season, and the ones who do find a willing female, go at it with such hormone-driven fury, they frequently die after the act, from exhaustion and blood-poisoning.
Then their fellow males, who missed out on the jump, gather around the corpse for a snack.
@@uncletiggermclaren7592 yeah i found six dead ones in a bucket , it wasnt that big and or high , we figured that they couldnt find a female . any port in a storm I guess.
Yeah, the boys go on a mental rooting binge and then die, leaving only pregnant females in the population for part of the year. The girls like to give birth in draws for some reason, I’ve found them with babies in my workshop. Open a draw to get out tools and there’s a bunch of gum leaves and a stroppy mum with a load of little ones hanging on her.
@@uncletiggermclaren7592 That's some extreme aussie heat.
Thank you for coming
Your clay looked so high quality here, it’d be cool to see you try making pots by rolling the clay flat into an rectangle and rolling that around something like another pot to form a cylinder then placing in on a circle for a bottom
You win some and lose some. I think your ratio to winning and losing is much greater than most folks. Great video as always!
Even if the ratio was bad, if each loss doesn't cripple you and each win brings you closer to a goal, that's still progress.
@@r3dp9 Very true!
-Pie, BFB 1
that hut shot at 11:16 is a masterpiece
It seemed like a moment of mourning. As though he went to go rest after an emotional setback.
Seeing the process and learning from failures is so inspiring! Can't wait for the next experiment! 👏🔥
This channel is comfy and one of the few remaining channels with little or no talking. You arent gonna suddenly tell me about nord vpn, raid shadow legends, you arent going to tell me your milquetoast opinions about a recent event, you arent going to tell me someone was unaliving themselves, you arent british, etc. I just wanted to say thanks.
Watching primitive technology is is how i pay respect to my ancestors
The people who annoy others with the sound, dust and pollen released when shredding pruned tree limbs could place the limbs in a pile, through a wet season, and picking out the remaining wood, when the weather can dry them, to make charcoal like this and get high quality leaf compost, too.
Primitive technology getting my ass to go "Woah! That's a big pot!"
I know! Half a meter in diameter and height seems like a very big pot! Too big for the structure it had, it turned out, but still an impressive creation considering the manufacturing facilities. Now I'm wondering what else he might create if that could be made a practical size.
My guy, John, owning up to his mistakes and uploading them to let us know that its not the end of the world and he will prosper
It’s always great to see this holdover from the long gone ara of real content on CZcams still showing us these fun ancient tech videos.
i love that you still put experiments online that don't work. The scientific method ensures that, regardless of the result, we learned something from it. Its quite impressive just how much gas from the wood was released and demonstrates just how flammable it is. Love your work as always
I get so much peace watching these. Thanks for posting. Thanks for your channel.
Indeed, kind of a letdown when his videos end
Turn on closed captions for detailed video descriptions. Love watching these videos and with descriptions makes it even better! Can't believe I never noticed this before.
Thank you for every last one of these. Each one is both a window into the past, and a guide to rebuilding if the worst should happen. Thank you and good luck.
I’m sorry to see the pot didn’t work out, but glad that you posted the video. It makes for a great learning experience and there’s still plenty of scrap pieces to use.
It was also cool to see the wood gas coming out and igniting.
But the small pot worked very well.
2:25 without any subtitles i was able to understand that he was showing the wood on the right wasn't burned through enough. he transcends language.
There is a reason, why most cultures ended up with simple charcoal mounds. You have exactly documented the process of experimentation, many of our ancestors went through themselves and decided that it is not worth the hassle. I like this channel as an example of "experimental archaeology".
you know that meme of the people in the bar watching a screen and then they freak out?
someone needs to make that meme and put 'fire by friction' on the screen. Every video I wait for the 'fire by friction' part and I get excited every time it shows up again lmao
Imagine how much grog remnants there are in the ground from failed pottery projects throughout history.
Dig anywhere in England and you're moderately likely to find old pottery. I've pulled up a bunch digging in my garden, though it's all been 18th and 19th century stuff.
@@jake-rg3fd thats cool. I wish we had that kind of history in america
What is the meaning of grog. I couldn't find other meaning than some kind of alcoholic drink.
@@stukker it is an aggregate (made from crushed fired pottery) added to clay to make it stronger. Think like gravel in concrete. It also makes working it much easier, less fatty. And though not obvious in this video, it reduces the chance of cracks.
I'd rather wonder how many "mountains" and "hills" were once bricks and stonework.
The massive pot was pretty cool though! Add me to the long list of people that are intrigued by the failed attempts and the lessons you’ve gained from them. It can be tough to get to a place where you view things as learning opportunities, especially after taking on the risk of losing all the time and effort put in, but what else is life but a series of challenges and mistakes? Great video!
you know it's amazing that even though he's proven time and time again he can strart a fire through friction, that he h's the integrity to continue to do so for all of his projects, we all know he's capable of it, but the fact that he doesn't take a short cut to put out more content is admirable.
May not have been the success you would have liked, but that was a spectacular display. Those yellow flames were vibrant and gorgeous.
The jet of flame coming out of stone-age materials is great
The original clay dragon.
The dedication and perserverance you put into making your projects is such an inspiration. How you casually made the biggest pot ever with that technique is just awesome.
I rarely shed tears, but I wept as I imagined the steady efforts of mankind in the past.
How much time must have been required to create this large pot?
Even while I was making it, I felt that this was an incredibly difficult undertaking. The moment it broke, I was in tears.
You learn more through failure than success. I always drop everything to watch your uploads. It's entertaining to watch and learn the processes you go through.
Two things :
-I'm absolutely amazed at the difference in strength between wood and charcoal, even when heated in the same pot.
- Random question : how thick is your Aussie accent?
Doesn't he live in New Zealand? So it would be a New Zealander accent?
@@LoganChristianson northeastern australia, actually. I've been watching for about a decade now and look forward to the next one.
His accent is so thick, you can walk on it while it mocks you.
He doesn't have an accent, he is still centuries away from inventing spoken language
He's in Queensland, Australia
P.T is the best. Watching this, an idea sprung to mind: Try the opposite of a charcoal mound. dig a fairly deep pit, start a fire at the bottom, fill the entire pit with wood, then place a lid over the pit (When the fire reaches the top).
Alternately, a small ceramic pipe (made from short interlocking sections) could feed in air at the bottom of the pit, and the fire instead lit on top. The lid could then be put on fairly soon after, and when the fire matures, plug the draft pipe and surface vent.
Charcoal is made in a furnace on the floor, which introduces the wood with logs vertically, has a door and about 6 vents, which are open at the start of the flame, then closed and wait up to 8 days to cool down.
One of my favorite things about your channel is that you show the successes and the failures as they happen. Thank you for sharing your journey.
Everything is fine when primitive technology uploads :3
You should try Bisque firing your clay before the high-heat firing! Idk if you have covered this before, but it could help increase the heat and thermal shock resistance!
1. Shape your clay, with your grog mixture (20-30%)
2. Bisque fire your clay
3. Add a glaze of some kind to reduce porous property. You could do this with clay + wood ash. Skip this step if you want a porous clay product!
4. High-heat fire your clay
Can we just take a moment to commend this man for sharing his failures as well as successes? This is how true science is supposed to be done. You're a credit to the human race.
if you put a hole at the bottom of the charge pot the gas would be direct into the fire - less wood as fuel input needed
I lke how you think, put all that "wood gas" to good use.
Might make it difficult to seal off the vent at the end of the firing?
I think the gas would be trapped in the top, accumulating until the flames ignite it and causes an explosion.
@@wallacechui9857 the volume of the gas is many times larger than the volume of the wood, and the chamber is full of wood to around 70% to 80%, which means that as soon as the gas is produced, it starts to displace all the remaining air, which exits through the bottom hole. Once the inside atmosphere is 100% wood gas, there is no oxygen left to burn it or cause an explosion, so it wouldn't really happen.
This applies to any pressurized vessel, such as a gas tank with a hole in it, as long a the tank can hold the pressure without rupturing, the exit velocity of the gas is high enough to not let oxygen in, and in some cases it's high enough to blow the flame out, hence the usual need for a larger flare at the end of a burner, following Bernoulli's equation.
I have designed and built quite a number of burners throughout my life, using different fuels and you always need to account for burnback velocity of the mixture to properly size both the mixing tube and the exit area. So, as long as you keep this particular exit hole below 3/4 of an inch in diameter, you should have enough exit velocity to make a nice jet, a larger hole will also not cause an explosion, but it will give you a "lazy" flame.
Wouldn't work. Gas rises. And the hole would burn the would-be-charcoal wood to ash.
Charcoal is made by heating wood to high temperature in an oxygen free atmosphere. That is why he has to seal it in.
It carburizes the wood, evaporating all the water in it and leaving the carbon in the cellulose walls of the wood cells. That water and some of the carbon react under the high temperature to make wood gas, which is mostly Methanol. You can condense it to make Wood Alcohol, which is really really poisonous, very small doses can cause permanent blindness and even death. Breathing it is also dangerous. Beter to burn it.
Fun fact: PURE methanol flame emits light only in the infrared range. It's literally invisible fire.
Somewhere in an alternate universe, there's a stoneage guy making youtube videos about advanced technology.
And there's you, making iron age/blacksmithing videos. nice channel!
probably a proto-vietnamese making the first hd cam
yea its called joe rogan
I love watching his YouRock -videos- moving stone pictures!
Don't forget to turn on subtitles / closed captioning!!! He uses those to tell everyone what he is doing.
YAY THIS VIDEO IS EXACTLY WHAT I WAS LOOKING FOR
In no way is this a failure. You experimented with a new idea and it didn't work. You still got some usable crog out of it and now you know what not to do when producing charcoal. Lessons learned the hard way are best remembered. Good job, dude.
It might be easier to fire something that large as 2 separate halves that you can join together with mud for making charcoal. Then, once your charcoal is finished, you can simply break the mud seal and pull the pot open like a book to access all of it more easily. Then you won't need to rebuild most of a mound each time!
Even better would be an open cylinder with two lids. That way, the expansion isn't being constrained.
Who else plays these videos at reduced speed to fully appreciate the work?
Also, I was sad when that giant pot fell apart.
I always watch twice -- once just to enjoy the process & 2nd time with captions to understand the what & why.
@@Tooling-Around Same! just watching the work is so soothing
My default is 3x but I watch these at regular speed
showing also your failures and experiences is so awesome. it really shows how many different methods there are to do such primitive things and the amount of time people took back then to find out all that
Man . . . you should be so proud of the things you have made. Huts, new techniques for various things, gardens, cement, forges, and so much more.
Edit: It's a shame that the giant pot broke. I wonder what the issue was? Not dry enough? Too thin walls? Not enough/too much grog?
You really do inspire us all.
Ive been researching steel smelting for a number of years now, i have yet to build a bloomry, blast furnace, or just a furnace capable of melting iron, but i do have lots of magnetite that ive collected.
Its Always a good day when you upload
My dude accidently invented a primitive gas cooker!
Isn't it just the process a rocket stove isolates?
idk how many people are aware. But u can add starch water (like from cooked rice) to clay in order to strengthen it, and make it more malleable. Also when using the "sausage" method to make the pots, by adding a slight lip on the inner side of the layers before adding another layer. Each layer then overlaps virtually more adding addition strength.
I learn more from these videos than any other channel, simply because they don't just show what works, they include the entire experimentation process.
7:03 - "Don't break. Don't break. Don't break. Don't break!"
@Agar-agarpowder Seriously, when he was building it I was thinking, "this thing is huge. It's going to weigh a ton. How in the world is he going to move it?" Then it cuts to him hulking out trying to carefully place it lol
@@jackinthebox301 it's an absolute monster of a pot. It's gotta weigh at least 50kg the way he's straining- dude is a beast.
National Geographic has been real quiet since this dropped
Its nice to also see the "failures" since it shows the true nature of trying somethimg out in your hobby. It makes you very humble and authentic.
You hear a "Hey, listen" in the distance and instantly fear for your pot's safety.
Very cool! But I wonder if your scaling issue is the reason most historic charcoal kilns where more like brick ovens then clay "barrels", would be really cool to see you build a permanent charcoal kiln out of your brick. Stay awesome.
I was going to suggest the same thing, he has the bricks and wood ash cement. I think his goal is and iron axe, so he's going to need a LOT of charcoal.
Shame it was a failure, but great to watch as always. I imagine the first person to get flames like that would have thought it was witchcraft with how intense it was 🤣

Great video as usual! Keep up the good work!
The way that ALL materials are scarce means that even when a project "fails" you're still left with a heap of things that can be used for other projects sooner or later, even if it's just grog.
Appreciate your authenticity, keep being real

He's _always_ been ai-generated.
STOP doing whatever, new video uploaded !!!
C'est exactement ce que je me suis dit, mais en français.
Unless you're John Plant, then keep doing what you're doing 😆
Or in this case maybe not bc it didn't work out, but you know what I mean lol
But I am cooking for my child
Don't forget to turn on subtitles / closed captioning!!! He uses those to tell everyone what he is doing.
@@tulipalll really ?
I'm that comment in every PT video pointing out what a flex it is to show us the fire starting process from the start every time
Tried to make some charcoal in my backyard one summer. That was so fun and interesting. It's really rewarding to understand that I can produce something so usefull.
Now I'm thinking about the giant pot more than the charcoal!
Maybe you just have to fire that thing much much slower? Also I imagine the shrinkage (thinking in horizontal cross-sections here) would be wildly different between the bottom and the sides. Maybe a narrower bottom and sloping the sides in to meet it would help with that.
In the glass industry while making the clay pot of that size they have much thicker walls. Pot have to dry longer too. Maybe that's the way
crazy how a video about a man producing charcoal from scratch is soothing me inside, cleansing me from the sooth that is the tiredness from everyday mundane job
Your videos are very stimulating for my cat, Rocco. We love watching every episode together. Thank you 💜
Speaking of failures, I've been attempting bow drill fire for 3 months. I'm 60% successful now. The first fire is a memory I'll never forget. Hand drill fire in seconds! Wow that is skill.
it's amazing the quality of the charcoal in the first pot, Gonna be interesting to see what he can do to reinforce the large pot, perhaps relief cuts to allow for expansion of the clay, reducing the chance of random cracks? great video!
I think the conclusion was that it's not worth the extra work and he will instead just pile wood up then create a clay mound around that then cook it.
For very tough refractory we mix together ceramic fibres with the main refractory compound. Not sure if you could do that with primitive technology short of liquifying rock with some kind of coke and air blast furnace to make rockwool.
The easier option is to have a more even temperature distribution, that being a draft kiln with solid walls and a ton of thermal mass.
@@K0wfaceIt was but he needs to add some fiber into the clay like shreded dry grass so it helps bind all the clay together and he just needs to let the clay fire for longer since it obviously didn't fully dry thus why it cracked. I'd say a full 24v hour burn then letting it slowly cool down for another day. Generally how people do porcelain.
@@SilvaDreams I have doubts about the lifespan of grass fibers inside an active kiln.
@@WyvernYT It doesn't need to last forever, it's merely to act as a binder as the clay dries. Yes it will carbonize when fired but you aren't using a lot of it in the mix either, just a few percentage of the mass. It's a common insulation method in making your own bronze and early iron age smeltery and used in adobe siding too.
