A tip for baking in a wood oven: the fire will always burn your food. What you want to do is get the oven really hot with a fire, then put it out and cook with the residual heat.
Also, you want all the walls of the dome to be as hot as possible. It can take several hours. Then, as @zinckensteel says, you wipe down the floor with a wet mop to get rid of the ash and cool the floor, so that it doesn’t just burn the underside.
This sort of underscores what has been a long-running issue with Andy's methodology: he tries to test or use the tools he makes with methods he doesn't know how to conduct properly. This always leads to things not working the way they should and would if he knew what he was doing. If he actually knew, for example, how to properly cook something in a wood-fired oven, the pizza test would have been far more successful and the end results he's going to get from his oven/kiln would be far better than what I'm guessing he's actually going to get. If you don't know how to properly conduct the testing process, your test results will be wrong and so will your final results. Many of the failures or marginally acceptable results he's gotten on this journey can be traced back to incomplete knowledge of the actual process and making assumptions on how to do something rather than finding out how to really do it.
@@wickideazy Well I imagine that he is intentionally trying to do things manually, on his own. Just like how these "First people" would've done so. The first people to cook in a brick oven probably didn't have all the techniques down either, they probably would've burned something or broken another thing. That's part of the learning process of these "new" technologies, the very thing he's trying to figure out.
Probably relays first. They're a lot easier and serve the same purpose. But he needs to discover electricity before all of that and maybe make a leyden jar and eventually a voltaic pile.
@@nightfox6738 Well relays can't amplify a signal, they can only replace vacuum tubes in computers, but he could build a carbon amplifier, which is probably good enough for everything that doesn't involve radio frequencies
@@nightfox6738 I'm pretty sure he could technically build basic logic circuits with bronze and the previously unlocked iron file, that stuff can be made out of lego, but I agree that it would be great to see some kind of computing done on this channel in the future!
I must say, I'm really impressed. The moment you arranged the bricks in a circle I was like "Here we go again", then you corrected yourself and made a really good square furnace. The arch was also skillfully built. I'm really impressed by the effort you put to do it right this time
OMG I love your little kiln design! As a ceramic artist myself, I might have to think of making a little kiln like this for myself. One tip I would give though as you refine the kiln, don't use mortar. A LOT of pottery kilns today and in the past didn't require mortar. This allows for easy improvements and maintenance but also makes it so you can reuse old bricks, saving on money. Even with an arch, tension is usually enough to keep them in place without mortar. What you will need though is some metal framework to counter any shifting and that will also help with constructing a solid door. Same with the shelving, you can use brick shelving inside but you probably would better to not mortar them in place either in case you need to change arrangements for larger items. Another tip, unlock different brick types. Some really good kilns I've used have different brick types layered together. The best I've seen use soft bricks on the inside and hard bricks on the outside. You seemed to have mostly used hard bricks. Layering the two types will dramatically even out and hold in more heat, allowing you to upgrade your kiln to higher temps that are much easier to control.
You should look into Raku firing! It's a lot easier and more movable way of firing at home. Just need to build a sturdy metal cage, add fancy fire proof material (ceramic fiber) for insulation, then add fire. When I did it we used what was basically a propane tank flame thrower. It only takes a few hours at most too vs days. Looking online, there are a ton of resources on how to do it too. Although they seem to opt for using preexisting metal objects to make the kilm instead of making it yourself from rolls of metal netting. Which is probably even easier
I know it. Like dude always builds everything so sloppy and gets either cement, caveman glue, or mud all over everything and everywhere. I know people will say it’s easier said then done and I say back to that construction! Which I’ve done the last 12 years. We do almost everything he builds on a daily basis and it’s neat. Only reason I’m complaining is because of the results. He would have far better results if he took his time and made them neat. Do you think the Roman who based his entire livelihood off pottery or glass built his ovens like that?? Hell nah and the work is still around to prove it.
@@dylanbennett958 Survivor bias, to that last comment. Other than that I agree. Roman concrete was softer than normal concrete when the Romans were using it; it wasn't a miracle material, it took thousands of years to harden up and become better than our concrete, but thousands of years is too long of a set time. Roman concrete is another great example of something people who talk about the Romans believe.
@@IseeDeadLlamas The pottery wheel showed that really well. Even the basics of smoothing out the top and using a sealant that wasn't going to flake off immediately made a massive difference. It was simple, sure, but it showed that some effort went into making a finished product.
@@5avan10 Doesn't even need coals. A wood fire that heats the oven then you can cook on the residual heat for several days before you need a fire again.

Grog is great to add to clay to stabilize it as it dries out and is fired. It does tend to effect surface finish, but it is great to use otherwise. Plus for civilizations in the past, finding broken pots to make it was super easy. Your cob is way too wet and less grass in it. You should be able to pick up a couple of handfuls once it is mixed, work them into a ball (also called a cob in some cultures) and then slap the ball into the location you want to put it to attach it. After you have a few balls in an area "thrown", you can then smooth it out some. After the cob has set some, you can then smooth the exterior. A lime or cement plaster then goes over the top for water proofing and protection against damage, including highlighting where damage happened. Once a month or so, go around and inspect it, patching any cracks or holes. There will be cracks and holes. As easy and effective as this building style is, it takes a lot of maintenance when compared to other materials. This is why important structures were made of bricks at least and vitals structures out of stone.
I would like to see Andy and crew take some time to focus on craftsmanship. I have to say I’m surprised we’re this many years in and it still feels like everything is done in a sloppy way. I think they would have a lot more success with their products if they took some time to develop technique. (Watching them fill the brick molds, I’m not surprised their bricks weren’t more successful; it looks like a lot of air is getting trapped in there.) I love this channel and have watched every single episode; I click on every new episode the day it comes out so please don’t take this the wrong way.
Somebody that's actually worked with mortar might know that better than me. But wasn't his especially watery? I feel like it should be just barely more liquid than cement. If at all.
@@Briaaanz Yeah definitely looks like clay slip, and honestly makes sense; you want to use the slip to fire-harden into more ceramic and basically weld the kiln together, after all. Sure, cement-as-mortar can work, but it still deteriorates with heat, nand the rapid heating process of the kiln would likely introduce cracking and possibly even spalling from thermal shock, and eventually at higher temperatures, molecular decomposition as it can no longer hold its hydrated form and begins to crumble into powder. This is why firebrick is its own thing, and not just concrete cement, too.
Making a frozen pizza in there is gonna be a roughy. You need proper freshly made dough, a pizza like that just needs about 4-7 minutes in an oven like that and will be crisp without burning the toppings. Gennaro Contaldo got a good youtube video for the dough and oven use.
Me and my friends have been working on making our own oven out by a lake from the clay in the lake. You guys were the inspiration! Keep up the amazing work 😁
Andy: guys, we need refractory bricks for a kiln. HTME team: but our brick making abilities are nowhere there yet! Andy: alright, we’ll use a new “recipe”, fire them and show on the camera that they won’t miserably break, and we’ll call this “unlocked” to get the rest from the hardware store. HTME team: (thinks about switching to Diresta channel)
It has already been explained that this is the standard procedure. On a youtube video specifically about addressing the challenge of making things "from scratch". Years ago. The whole team came up with it and agreed on the rules.
When we do Wood fire pizzas at our Winery we usually get the ovens around 600-800 degrees and a pizza will cook in 30 seconds to 2 minuets. The trick is once you've heated up your floor and pushed the fire back is to surround the cooking area as much as possible and pre cook the crust.
i must know, where do you get all this clay? do you have a giant clay cleaning setup? or do you buy it online in bulk somehow? or have you just found an area with lots of pure clay you can use straight away?
Its amazing to see how different Andy looks nowadays... Way more muscular, kinda more grown up in a characteristic way. I'm so glad I can be here for this whole journey
In Uni, we used a rack to cook several pizza's in one of the department furnaces. It was only used to heat treat steel so we guessed it would be ok.. and with a perfect control of temperature.... those were some good pizzas for lunch while we worked on a project.
To control the temperature you can add a chimney on top of main fire chamber that has is the same size as a brick inside. You then leave a brick sized hole in the side of the chimney and slide a brick in and out to control the flow between this chimney and the kiln.
Some other have commented on it already: the problem is not just the oven but how it is used. In a wood-fire oven (don't know the right term in English) you don't keep the fire alive, you have to burn it beforehand and then cook when only embers are left and you have to move the food often or it'll burn quickly
My inner chef was screaming in pain when he started pulling out the pizzas. Granted, i probably couldn't do much better, but dear god man never take your eye off the food! That's, like, rule number one in the kitchen!
If you end up trying out ideas to raise the temp in the main chamber, I'd like to suggest a modification. Have the heat come in at the top of the chamber and keep the outflow to the chimney low. I would imagine this will slow down the hot air from going straight out while building the hottest pocket at the top and letting out the coldest air. I hope you try this idea. Great video BTW
I love this, also i think a better way to adjust the flow will really help. Maybe as simple as a stick on the chimney with a cap attached at the top you can rotate around over the hole?
I make absolutely KILLER pan pizza by first cooking the bottom until it starts to slightly brown, and then putting the pan and pie in it in a 450degree toaster oven to cook for around 11-13min. I know toaster ovens aren’t ancient, but for that old method or modern ones I don’t think 500-1000degree ovens as being necessary at all if you like a nice pan pizza, and I’m sure a steel pan could be subbed out for a clay/ceramic one. :)
I'm not a mason or anything but that mortar looks a little too watery? It should keep its form better and not be runny when you're laying bricks I believe?
I think the mortar becomes a weak point at high temperatures thats why it's kinda runny to better get into the pores of the brick and to remove the surface area for it to crumble away. Just a guess though
You are right, but also not. Cement has diferent thermal properties than a brick. When you are building a kiln you want as little cement as possible, otherwise the thing will deform and crack terribly.
It’s not actually mortar, it’s slip so dries and hardens just like clay would so as it gets used more and more it hardens, whereas with mortar it would depend on the sand and mixture used. Slip just reinforces the kiln
So if you want to cook pizza in a wood fired oven you have to get the fire to one side and have quite a bit of space between where the fire is and where the pizza is, you’d like to also have the flames to not go towards the pizza but away so that you bake it more than blast it with flames. You want a thinner pizza so that it cooks quickly and doesn’t burn and a very wet dough for the same reason, turn it quickly and in less than 60sec it will be cooked perfectly. Last thing is to not cook it near the entrance to the oven because one side is going to be extremely hot and the other extremely cold so it will not heat the stone on the bottom and not cook the pizza
I feel like I may have missed something, is there a fully laid out tech tree that you are following? or are you just loosely following a structure based on what we discovered throughout our history?
i would like to see what you could make with scratch in the wilderness with the natural elements and luke can actually build a house from scratch like it is so amazing to be kinda primitive
For firing a pizza or bread, you typically heat the oven, then when the flames are gone, put the pizza or bread in. Makes it more like an oven than a campfire
For the crushed ceramics, you don't need to make ceramics from the clay, you can bake the dirt directly, and it will turn into ceramics. Just shove piles of loose dirt, and crushing it will be much easier. And modern pizza is right, but how about you make your own pizza, from scratch? You can even use different sauces, instead of ketchup. it just has to be something which is sweet and sour, and to which to add salt, and you've got a tomato paste replaccement. *Contrats on the permanent setup!*
A great channel called tasting history has recently done a great video on the history of pizza (including the "original" pizza, and the american version)
@@DH-xw6jp True. There are more discussion on the Discord server. I wonder how long it will take Andy to make an actual printer (block printer made from wood and/or terracotta), and a treadle-powered fan, and treadle-powered lathe, and a treadle grindstone, and a few other things I kept suggesting since a year or two ago.
The issue you have baking a pizza is that you still have the fire going. Heat the baking area with the fire and then put the pizza in, the brick will hold heat. Kind of like pre-heating an oven.
How we used to bake bread in medieval Europe is by having a brick or stone oven. Which we would set a fire in. Then once all the wood was reduced to ashes, we would place the bread on a wrack close to the bottom and close the door quickly. Letting the ambient heat evenly bake the bread. Some times it took 2 fires to bake it just right. Especially if it was a large baker's oven. But keep an eye on it if you need 2 fires. You do not want to burn your bread. Back then, baking was more of an art form than a science. One door for a oven that might be easy is a stone/concrete wheel in a groove. That you roll into place tightly infront of the entrance.
Heyy, i wonder if the stove being only applical for a certian amount of uses per build is what gives take to 3 meals a day. I have always been curious why 3 meals a day? Im hungery all day lol
If you want to cook a pizza in it, my top tip would be to let the wood all burn up, leaving hot embers, heat cooks, flame burns, I learned this while doing various bushcraft courses
why did you upload it for a long time ?? 😭 :) I really like your knowledge with sophisticated editing :), I really like it Why are there no subtitles Edit: btw why are there no subtitles? i come from Indonesia bro so sometimes you have to need English subtitles to automatically translate into Indonesian :), and yup I type with the help of google translate :)
Nice kiln, but one thing that sticks out to me is that cob is a terrible material for insulation. Cob gives thermal mass, aka retains temperature for a while, but does not really insulate. For insulation you should probably use something like a fluffy mix of straw, and pure clay on top of the cob layer, and after that maybe another cob layer once it's dry, just to be on the safe side.
This one didn’t age quite too well… all jokes aside, I’m glad to see that you’re making the most out of an extremely shitty situation and I respect that.
For baking pizza in a woodfire oven you need to first of all make it very hot, also preheat the plates on which you put your pizza and lastly keep it inside for a very short time, usually just a few minutes
for what it's worth, pizza ovens usually have the fire above the bricks so as to warm the bricks and make the bottom cook. since the bricks are insulating, having the fire under the bricks will mean the heat never reaches the pizza.
A bread oven is designed differently, not fancy just different. It would make a nice video, as you have plenty of good bricks. And you could trap wild yeast,(easy!) to make it time period appropriate.
The rule is: once they successfully made something with ancient technology and tools, they can use modern versions/store bought for future projects. Otherwise everything would take years instead of weeks.
@@Geeksmithingno that was the rule established in episode 1 of the relaunch the issue is he hasn't mentioned that rule since episode 1 so even if he isn't "cheating" it looks like he is because new people watching aren't aware of that rule
@@exilestudios9546 I was referring to the OP stating he needs to make EVERYTHING required to make a thing, including tools. I am aware of the relaunch rules.
If you want to use a bit of modern knowledge, for ceramics and metallurgy where you are operating close to the maximum temperature, preheating the intake air using either the exhaust, heat gun or separate, secondary fire will increase the flame temperature and therefore drastically improve fuel efficiency and process time (if your refractories can handle it). Some steel plants use natural gas to keep the steel molten. Due to the low flame temperature (and high water content in exhaust) this wastes 85% of the available energy.
Adjusting the desk and chair to fit you is the best. At least for gaming its ideal for your legs to be at a 90 degree and the desk to be at the right height so that your arm rests comfortably and slightly over 90
Am I the only doubting that the bricks at 3:20 are the same bricks as later shown at 3:40? The later ones look _way_ more uniform and even than the ones shown earlier did. Edit: Yeah, the later bricks are clearly store bought, as evidenced by the giant pallet of them in the background. I don't get why the first part was even necessary when you are just going to go straight to store bought bricks.
to unlock the bricks in the tech tree. They deemed that their brick making skill and technique was at such a level, that it is then "unlocked' and then they can use commercially available bricks. They are not trying to pass off the DIY bricks as the ones later in the video.
@@Geeksmithing So far, I haven't seen any bricks of a quality similar to those commercial bricks. Let us be honest here, they made a brick that looked "good enough", with its only test being whether it cracked in a fire, and then went straight to the far superior commercial bricks(which also comes with pre-built angular bricks, as shown at 8:23)
@@Geeksmithing and you don't see how that can mislead people? Especially when they have not reminded people of that rule since episode 1? Face facts this channel relies on people thinking they are doing this 100% themselves and of they break that illusion then they lose money.

@@Briaaanz Yeah definitely looks like clay slip, and honestly makes sense; you want to use the slip to fire-harden into more ceramic and basically weld the kiln together, after all. Sure, cement-as-mortar can work, but it still deteriorates with heat, nand the rapid heating process of the kiln would likely introduce cracking and possibly even spalling from thermal shock, and eventually at higher temperatures, molecular decomposition as it can no longer hold its hydrated form and begins to crumble into powder. This is why firebrick is its own thing, and not just concrete cement, too.
Making a frozen pizza in there is gonna be a roughy. You need proper freshly made dough, a pizza like that just needs about 4-7 minutes in an oven like that and will be crisp without burning the toppings. Gennaro Contaldo got a good youtube video for the dough and oven use.
Me and my friends have been working on making our own oven out by a lake from the clay in the lake. You guys were the inspiration! Keep up the amazing work 😁
Andy: guys, we need refractory bricks for a kiln.
HTME team: but our brick making abilities are nowhere there yet!
Andy: alright, we’ll use a new “recipe”, fire them and show on the camera that they won’t miserably break, and we’ll call this “unlocked” to get the rest from the hardware store.
HTME team: (thinks about switching to Diresta channel)
It has already been explained that this is the standard procedure. On a youtube video specifically about addressing the challenge of making things "from scratch". Years ago. The whole team came up with it and agreed on the rules.
@@PixlRainbow Exactly.
When we do Wood fire pizzas at our Winery we usually get the ovens around 600-800 degrees and a pizza will cook in 30 seconds to 2 minuets. The trick is once you've heated up your floor and pushed the fire back is to surround the cooking area as much as possible and pre cook the crust.
Maybe the flames are the issue
Radiant heat should be better for pizza i guess
i must know, where do you get all this clay? do you have a giant clay cleaning setup? or do you buy it online in bulk somehow? or have you just found an area with lots of pure clay you can use straight away?
2030: Andy makes a Nuclear Reactor that makes pizzas faster than a microwave.
This must be done
Now I wonder if that can happen. Imma bust my calculator out now
it also gives you cancer
9 years to go
Somewhere a mason is having a mild heart attack and dead ones are spinning in their graves LOL
If you have limited access to technology, Celsius really shines compared to Farenheit, 0°C water freezes, 100°C water boils.
Its amazing to see how different Andy looks nowadays... Way more muscular, kinda more grown up in a characteristic way. I'm so glad I can be here for this whole journey
Construction worker: "Andy, how much lime do you want?"
Andy at 7:16: "Yes"
First few seconds and it already looks like ur probably going to burn the pizza lol
This channel is so underrated and deserve more support
What was the final brick recipe, with the powdered ceramics?
In Uni, we used a rack to cook several pizza's in one of the department furnaces. It was only used to heat treat steel so we guessed it would be ok.. and with a perfect control of temperature.... those were some good pizzas for lunch while we worked on a project.
To control the temperature you can add a chimney on top of main fire chamber that has is the same size as a brick inside. You then leave a brick sized hole in the side of the chimney and slide a brick in and out to control the flow between this chimney and the kiln.
You need mor mass in your kiln. Triple the wall thickness and fill the wall with sand.
As others have mentioned, you're supposed to get the oven hot, then extinguish the fire and cook with the heat radiating from the brick.
Some other have commented on it already: the problem is not just the oven but how it is used.
In a wood-fire oven (don't know the right term in English) you don't keep the fire alive, you have to burn it beforehand and then cook when only embers are left and you have to move the food often or it'll burn quickly
My inner chef was screaming in pain when he started pulling out the pizzas. Granted, i probably couldn't do much better, but dear god man never take your eye off the food! That's, like, rule number one in the kitchen!
If you end up trying out ideas to raise the temp in the main chamber, I'd like to suggest a modification. Have the heat come in at the top of the chamber and keep the outflow to the chimney low. I would imagine this will slow down the hot air from going straight out while building the hottest pocket at the top and letting out the coldest air. I hope you try this idea.
Great video BTW
I love this, also i think a better way to adjust the flow will really help. Maybe as simple as a stick on the chimney with a cap attached at the top you can rotate around over the hole?
"We'll be growing our own pizza"
Pepperoni? I think trying to make pepperoni would be interesting.
I spat my drink when he made the clarification for the glory holes 🤣
It would be cool if you made a food forest so you can forage for the ingredients
I make absolutely KILLER pan pizza by first cooking the bottom until it starts to slightly brown, and then putting the pan and pie in it in a 450degree toaster oven to cook for around 11-13min. I know toaster ovens aren’t ancient, but for that old method or modern ones I don’t think 500-1000degree ovens as being necessary at all if you like a nice pan pizza, and I’m sure a steel pan could be subbed out for a clay/ceramic one. :)
My planner: you have five assignments due at the end of the week, get to work!
My mind: MeDiEvAL PiZzA
I'm not a mason or anything but that mortar looks a little too watery? It should keep its form better and not be runny when you're laying bricks I believe?
It's gonna harden when heat is applied fusing the bricks together it's the same principle as glue or rubber cement.
I think the mortar becomes a weak point at high temperatures thats why it's kinda runny to better get into the pores of the brick and to remove the surface area for it to crumble away. Just a guess though
You are right, but also not. Cement has diferent thermal properties than a brick. When you are building a kiln you want as little cement as possible, otherwise the thing will deform and crack terribly.
It’s not actually mortar, it’s slip so dries and hardens just like clay would so as it gets used more and more it hardens, whereas with mortar it would depend on the sand and mixture used. Slip just reinforces the kiln
10:08 I imagine the building sound effect from lego games over this
So if you want to cook pizza in a wood fired oven you have to get the fire to one side and have quite a bit of space between where the fire is and where the pizza is, you’d like to also have the flames to not go towards the pizza but away so that you bake it more than blast it with flames. You want a thinner pizza so that it cooks quickly and doesn’t burn and a very wet dough for the same reason, turn it quickly and in less than 60sec it will be cooked perfectly. Last thing is to not cook it near the entrance to the oven because one side is going to be extremely hot and the other extremely cold so it will not heat the stone on the bottom and not cook the pizza
Definitely revisit making mortar.
I feel like I may have missed something, is there a fully laid out tech tree that you are following? or are you just loosely following a structure based on what we discovered throughout our history?
I cant belive I've been here since so early, when you were only relying on Patreon and spending thousands on a single video! I love this journey!
Those are some professionally perfect looking bricks
Yeah a little to perfect.....
@@Michael-fs5ct yeah...
because they just made proof o concept bricks and use pro ones for the kiln itself
@@Michael-fs5ct If you look closely, you can see that theres a perfect indent of a circle on the bricks
@@beardmaker yeah but they "forget" to say it...
And you invented the pizza stone! 😂
This video really fired me up to learn more about our historical technology development - Thank You!
I think he mentions them in an earlier video, but check out “The Knowledge” and “How to Invent Everything”
i would like to see what you could make with scratch in the wilderness with the natural elements and luke can actually build a house from scratch like it is so amazing to be kinda primitive
Do you need to unlock pyrometric cones to use them for testing the kiln temperature?
For firing a pizza or bread, you typically heat the oven, then when the flames are gone, put the pizza or bread in. Makes it more like an oven than a campfire
For the crushed ceramics, you don't need to make ceramics from the clay, you can bake the dirt directly, and it will turn into ceramics. Just shove piles of loose dirt, and crushing it will be much easier. And modern pizza is right, but how about you make your own pizza, from scratch? You can even use different sauces, instead of ketchup. it just has to be something which is sweet and sour, and to which to add salt, and you've got a tomato paste replaccement.
*Contrats on the permanent setup!*
A great channel called tasting history has recently done a great video on the history of pizza (including the "original" pizza, and the american version)
@@DH-xw6jp I saw that after watching this video an a few more. But *I've been suggesting the primitive pizza to Andy for a few months now.*
@@SapioiT probably was long as i have been suggesting a proper anvil.
Even a brozen block is better than a broken rock. Haha
@@DH-xw6jp True. There are more discussion on the Discord server. I wonder how long it will take Andy to make an actual printer (block printer made from wood and/or terracotta), and a treadle-powered fan, and treadle-powered lathe, and a treadle grindstone, and a few other things I kept suggesting since a year or two ago.
The issue you have baking a pizza is that you still have the fire going. Heat the baking area with the fire and then put the pizza in, the brick will hold heat. Kind of like pre-heating an oven.
I love this channel.
4:05 thank you for clearing that out
How we used to bake bread in medieval Europe is by having a brick or stone oven. Which we would set a fire in. Then once all the wood was reduced to ashes, we would place the bread on a wrack close to the bottom and close the door quickly. Letting the ambient heat evenly bake the bread. Some times it took 2 fires to bake it just right. Especially if it was a large baker's oven. But keep an eye on it if you need 2 fires. You do not want to burn your bread.
Back then, baking was more of an art form than a science.
One door for a oven that might be easy is a stone/concrete wheel in a groove. That you roll into place tightly infront of the entrance.
Heyy, i wonder if the stove being only applical for a certian amount of uses per build is what gives take to 3 meals a day. I have always been curious why 3 meals a day? Im hungery all day lol
For each view there is a italian crying for the wasted pizzas
Or crying because he was "cooking" frozen pizza!
It's a frozen one, so that's just a way to dispose of if.
If you want to cook a pizza in it, my top tip would be to let the wood all burn up, leaving hot embers, heat cooks, flame burns, I learned this while doing various bushcraft courses
So do you just plan on letting your wares anneal in the wares chamber while to furnace cools?
why did you upload it for a long time ?? 😭 :) I really like your knowledge with sophisticated editing :), I really like it

Nice kiln, but one thing that sticks out to me is that cob is a terrible material for insulation. Cob gives thermal mass, aka retains temperature for a while, but does not really insulate. For insulation you should probably use something like a fluffy mix of straw, and pure clay on top of the cob layer, and after that maybe another cob layer once it's dry, just to be on the safe side.
Try wetting the brick mould between each batch of bricks. That way they won't stick as much and be easier to get out.
Are you mudding with slip or is your mortar really that soupy?
This one didn’t age quite too well… all jokes aside, I’m glad to see that you’re making the most out of an extremely shitty situation and I respect that.
For baking pizza in a woodfire oven you need to first of all make it very hot, also preheat the plates on which you put your pizza and lastly keep it inside for a very short time, usually just a few minutes
Pizzas is Italy aren't cooked on plates, they're laid down in the oven and the fire is on the side of the oven
i am wondering how you made the bricks i know you are using fired pot dust to make it but what do you mixed it with?
When I was a kid I tried to cook a pizza on a bonfire and it turned out great!
Ok
@@starshot5172 ok!😀
@@darrylponton can I rasre
Should have used a freshly made and no frozen pizza, would have been easier to do.
for what it's worth, pizza ovens usually have the fire above the bricks so as to warm the bricks and make the bottom cook. since the bricks are insulating, having the fire under the bricks will mean the heat never reaches the pizza.
Is that a special kind of morter? It looks very thin and pasty.
I wonder if putting a mini wall to disperse the heat more evenly than right to left in the ceramics chamber would lead to a move even pizza cook.
lemme know when you guys are going to make a blast furnace please
I'm looking forward to unlocking manned space flight :-)
I was hoping that you would make a Neapolitan pizza, which benefits from such a high heat.
This channel can be so good
Now imagine how hard that arch would be to build without the supports. Makes you wonder how people do it without them 😅🧐 the skill needed is crazy.
I hope you make a dynamo because with dynamo you can do everything :) it even helps you to process iron bro
just growing some pizza XD 14:08
With all this work making a hotter furnace, crucible steel is practically guaranteed... Right?
A bread oven is designed differently, not fancy just different. It would make a nice video, as you have plenty of good bricks. And you could trap wild yeast,(easy!) to make it time period appropriate.
What happened to being limited to the TOOLS and materials only available to you? Those bricks look really modern and that mortar as well
The rule is: once they successfully made something with ancient technology and tools, they can use modern versions/store bought for future projects. Otherwise everything would take years instead of weeks.
That was the old rule before the relaunch a while back.
@@Geeksmithingno that was the rule established in episode 1 of the relaunch the issue is he hasn't mentioned that rule since episode 1 so even if he isn't "cheating" it looks like he is because new people watching aren't aware of that rule
@@exilestudios9546 I was referring to the OP stating he needs to make EVERYTHING required to make a thing, including tools. I am aware of the relaunch rules.
Nice professional looking bricks
What is the recipe for the strong brick?
If you want to use a bit of modern knowledge, for ceramics and metallurgy where you are operating close to the maximum temperature, preheating the intake air using either the exhaust, heat gun or separate, secondary fire will increase the flame temperature and therefore drastically improve fuel efficiency and process time (if your refractories can handle it). Some steel plants use natural gas to keep the steel molten. Due to the low flame temperature (and high water content in exhaust) this wastes 85% of the available energy.
Did you guys unlock heat resistant mortar?
Normal people: adjust the chair to fit the desk
Autonomous: adjust the desk to fit the chair
Adjusting the desk and chair to fit you is the best. At least for gaming its ideal for your legs to be at a 90 degree and the desk to be at the right height so that your arm rests comfortably and slightly over 90
I mean the idea is that the desk alternates between a normal desk and a *standing* desk, no chair.
@@Darasilverdragon yeah but for the normal desk case it needs the chair
Can you do porcelain? It's just as important as mastering glass

Am I the only doubting that the bricks at 3:20 are the same bricks as later shown at 3:40? The later ones look _way_ more uniform and even than the ones shown earlier did.
Edit: Yeah, the later bricks are clearly store bought, as evidenced by the giant pallet of them in the background. I don't get why the first part was even necessary when you are just going to go straight to store bought bricks.
to unlock the bricks in the tech tree. They deemed that their brick making skill and technique was at such a level, that it is then "unlocked' and then they can use commercially available bricks. They are not trying to pass off the DIY bricks as the ones later in the video.
@@Geeksmithing So far, I haven't seen any bricks of a quality similar to those commercial bricks. Let us be honest here, they made a brick that looked "good enough", with its only test being whether it cracked in a fire, and then went straight to the far superior commercial bricks(which also comes with pre-built angular bricks, as shown at 8:23)
@@ocadioan once they demonstrate the knowledge of fundamental technique and materials involved in making bricks, they move on.
@@Geeksmithing and you don't see how that can mislead people? Especially when they have not reminded people of that rule since episode 1? Face facts this channel relies on people thinking they are doing this 100% themselves and of they break that illusion then they lose money.
