I’ve had four successful firings in my backyard thanks to the information you share in your videos and I’m preheating now to burn a couple of coil & scrape ollas today. 🤞This channel is a treasure! Thanks, Andy!
I am running on four hours of sleep. I had a brain fart; I read that title as, "you can fire pottery without heat". I think I'll go for a nap after I watch this video.
Primitive pottery teaches you the philosophy of loss. I am used to having so much breakage that I started to make some pottery tools out of them and also chamotte by grinding them in a mortar. Those tempered with chamotte seem to come out better in fire than those tempered with sand. Also here in northern Sweden you don't have access to sand in winter: the soil is frozen under deep layers of snow.
worked like a charm for me, first time making pottery at home and it was easy to fire, i made two small pots to test and both survived with no cracks, great content, thanks!
I have a goal to make a cossack style clay pipe this year. These videos are a heaven send of information. Sourced some excellent wild clay and going to the lake tomorrow to fire a few pipe!
I’m so glad I’ve stumbled onto your videos! I live in the SF Bay Area and they literally give away clay by the truck load around here. My backyard is loaded. My wife and I are going to try to make some pottery based on your techniques. You’ve got my subscription

While it sucks that your St John’s Ppolychrome bowl broke in the firing, it makes me feel better about all my breakages. It’s not that I’m happy , but it’s reassuring to know that it happens to everyone at times.
@@AncientPottery Maybe you could do Kintsugi with some of the broken pottery? Not every piece would be suitable for that style, but surely some of them.
Thankyou so much for this video. I fired my first ever pots at home in a fire using clay from my own garden ( in the UK). I really don't think I would have had the confidence to give it a go without your videos. Just fantastic.
We just broke a huge jar,... went from perfect weather to squall in less than 5 minutes. We are thinking that pit-firing would keep wind shock from happening, but we are doing some experiments!

@@fionadia625 as long as its actually charcoal from firewood i think it is fine but regular coal has toxic fumes and things in it that might penetrate the clay im not 100 % sure about the regular coal toxicity though i just know that when you cook with coal you do it on a coal range that keeps the coal seperate from the food whereas charcoal you can cook the food right on the coals and its fineb just make sure its bbq rated coal and you should be fine though since thats meant for food
I just wanted to say thank you for sharing all your information-for free! I know you have the course but I like that you don’t push it or hide information. It makes me more likely to buy the course if I ever have the right space to try some of your firing and other techniques. Pottery is generally very expensive and inaccessible and you show how it can be cheap and completely accessible! Thank you, Andy!
I think pit firing is more popular because it has a more catchy name. Whenever I talk to people about firing like you do, they always say “oh yeah: a pit fire!” And I have to say, no it’s actually a “surface” firing, no pit needed. Anyway, we should come up with a catchier name for surface firing so it gets more attention.
I am sad that those beautiful pieces broke. They are so gorgeously painted. That probably took a long time to create. Anyway; I'm happy you shared this with us because I will soon need this knowledge.
Awesome video Andy! Good thing you were not using organic paint, you had quite a family of Ant's running around there early in the video, haha 😅 Wow that explosion sure was loud! Sad too. That fire must have got really hot! Those colors and results turned out just beautiful! Love that canteen!!!
Yeah the ants were crazy out there on that day. Thanks Will! Your name was mentioned a few times at the kiln conference last week, too bad you weren't there.
Hey Andy we’ve been watching all your videos and they’ve been so helpful! We just did a firing with a galvanized bucket and we are wondering if there is any technique to testing if your pottery did actually fire after it has cooled off. We do not yet have a thermometer so we couldn’t check the temperature during the firing. Our bucket is pretty tall so we were concerned it may have kept the fire too far from the pottery.
Try flicking the pot with your finger and see if they ring or have a dull thud. The ultimate test is to put water in the pot and see if it falls apart.
It will be used for cover sherds to protect pots in the firing until it breaks into pieces too small for that, then it will be ground and added into the clay for temper. In that way it will serve several uses.
I found your channel just as I started working with clay. Love your video on making your own clay and this one as well. Your cinematography adds very soothing touch. 😊 Makes me miss my home in Arizona. Do you have any advice for someone living in an apartment in the city? There are no community kilns around here and I don't believe there's anywhere nearby where I can legally start a fire..
Maybe try the brick and charcoal firing if you have little space, you can always pretend you are having a barbecue. Check out this video for details. ua-cam.com/video/ztLn3BsYuJ8/v-deo.htmlsi=mrX7-rvD8UarYZYq
Hi Andy, your videos are fascinating. Thank you for sharing your wealth of knowledge. Im wanting to fire some unpainted clay beads without having them discolour too much from the carbon. If I Suspend them on wires over the coals, and build a fire over the top do I need to protect them from the coals falling on top of them? build some sort of protective box around them? Would dumping them all together in a can in the coals provide enough oxygen to not discolour? Appreciate any tips.
Can you please 🙏 show what you do with clay after you formed your desire design like mug 🍵 if I done ✔️ what next? Should I put in the oven or let it dry on the sun 🌞 I watch you from Middle East.
I tried firing pottery in my wood stove but it seems like it did not get hot enough since my pots seem to disolve in water. I think i need to let more air in.
I'm trying to figure out how to access this technique with a modification since I am not allowed to burn where i live. I did however pick up a little saucer grill and hope that could make due? it wouldn't exactly breathe like the slots between the bricks though, any advice? btw I only intend on making miniatures to keep everything as mobile and accessible as possible :) thanks! been loving the little slivers of humor in your vids and love the raw common sense
Hi Andy, I made my first piece of pottery using clay from my own yard. I watched a lot of your videos and found out pottery is much harder than it seems. I made a bowl and when I fired it, it developed a crack down the side😢. Is there any way to repair this or is the only option is to try again???
I have a question, I live in Texas and there's a lot of dirt mixed in with the clay do I have to use water to separate it I already dried ground it down with two bricks I just wanted to know if I needed to separate the clay from the dirt? Also I have a mixture of red and white clay will that make any difference?
Yes, if your clay is too impure then you need to refine it a little and remove some of the non-clay particles. This video shows some different options for cleaning your clay ua-cam.com/video/ca20JkKFAcE/v-deo.htmlsi=P_AHA9EK1rLIwtiG And mixing clays can change the properties and the colors obviously.
I love watching your videos and it's nice to see when things go wrong rather than giving the untrue impression of infallibility. Have you considered using a wind break? It could be as simple as a sheet tied to two sticks.
One time I was teaching a workshop and when it came time to fire the wind was blowing so I was going to reschedule. The students talked me into trying it, saying that they would hold a piece of plywood to block the wind. Well it didn't work, the wind just eddied around behind the plywood and the pottery all came out black. In the ned we tied again on a different day and burned out all that black. It just doesn't work to try to fire in the wind.
@@AncientPottery Interesting, I hadn't considered that the wind would have to flow around the wood, it might have actually made the problem worse if the venturi effect or similar was at play. Ah well, it's nice to know that it doesn't work for future reference :)
Nice video. In some similar videos, youve talked about trying to dial in the right amount of fuel to get the firing you want. It occurs to me that the _mass_ of wood is the thing to measure. Assuming consistent moisture, ambient temperature, and wind speed, a given mass of wood should produce a reasonably similar effect each time. 8s this something you've tried?
No, I think the diameter of the wood is more important than the mass of the wood used. Because the size of the wood indicates the fuel-air mixture and how fast and intensely it will burn. Also the fuel moisture and species has a big effect too.
@@AncientPottery for sure, diameter will impact burn rate,which, I guess will impact temperature. Your goal is to reach a temperature, not dwell there, is that correct? I think mass would be useful for understanding the total amount of energy being produced, but says nothing about how fast it burns. 🤔
@@andrewsackville-west1609 large logs burn much slower and release their energy at a different rate. You need a certain amount of fuel burning at one time to reach the desired temps. Any wood burned 10 minutes ago will not help much now because it has already escaped into the atmosphere. This is the reality of firing without a kiln to hold in heat.
I live in Arizona, we have fire restrictions for several months each year. Once fires are allowed I usually fire on public land, National Forest or Bureau of Land Management.
So, question; since campfire firing can be unpredictable and you sometimes end up with much higher temperatures than you intended, should you make a habit of using high-temperature tolerant clay for this application?
Is there an advantage to the higher firing temperatures that can be obtained and maintained in ovens, furnaces, and kilns? Is it easier to control temperatures? Is it a more efficient and complete combustion of the fuel (like a rocket stove)? Is the resulting pottery more nonporous? I would think that it would be harder, but more brittle. Is it possible to repair exploded pottery by sintering the fragments back together?
Well, after seeing this video, I can see that temperature control should certainly be more of an advantage with a closed heating chamber. Wind would not be as much of an issue.
Yes there are many advantages to a kiln, more efficient use of fuel, higher temperatures can be reached, etc. It is also harder to get a good oxidation atmosphere in a kiln.
I haven’t done any pottery before but I find your videos intriguing. I also binge-watched a lot of TimeTeam during COVID, and there was a lot of ancient to historical era European pottery to see on that show. It’s made me wonder about trying to make something out of the wild clay in my area (Ontario, Canada). I know much of what you do stresses authenticity, but I wonder whether one can fire pottery in an old cast iron wood stove? Is controlling temperature mor or less of an issue with them?
I don't think the cast iron stove would withstand such high temperatures inside it, it will crack. But you can give it a try outdoors and see what happens.
@@AncientPottery I may try both, especially if some of my First Nation pals want to give it a try with me. But for several reasons I wondered about wood stoves. For much of the spring and summer we were under outdoor fire bans because of forest fire risk, but fires in stoves with stove pipes and spark guards are not subject to those bans. I would also think with a wood stove I should have more control the temperature by adjusting the amount of fuel, air supply, and chimney damper. Old wood stoves are easy to come by up here, as insurance companies ‘encourage’ people to upgrade to newer, certified stoves.
I’ve been experimenting with a metal trash can with charcoal. I drilled holes in the bottom of the can to let in more air to get the coals hot. I’ve had mixed, but encouraging results. I’ve had some very good hard ceramic results. Even my failures gave a sort of subpar terracotta. I’m still working out my process. I live in a very wet area of the Pacific Northwest, so the process shown here, firing on the open ground, isn’t practical for me.
Probably. Make a few clay objects that you won't miss if they explode, dry them thoroughly, and place them in different parts of the stove. You might also try altering the amount of fuel that you are burning. It might be necessary to gradually add more fuel rather than a bunch at once. I am curious to learn of your results if you decide to try it out.
Thank you. I'm going to try it, and the good thing is, I have less than zero chance of ruining any kind of artistic or practical creation. Winters are long and how much damage could I do? (Just kidding, Universe. I am truly at your mercy.) 😁@@AncientPottery
That will only protect against thermal shock, this kind of explosion is caused by moisture, not thermal shock and the broken pottery will not protect against that.
@@AncientPottery I'm sure of your experience in the field, I don't think you need lessons. By moisture do you mean interleaving water? Because it goes away from the piece over 200° c. I use a method that I learned from a wild ceramist friend of mine, his name is Aquilino Antonio Rodriguez Santana, he lives in the Canary Islands. He keeps the pieces on the embers from 150° to 400°, only after 400° does he stake the wood, like you did at minute 03:35 He rarely has breakups. I am aware that there are many other variables, such as the type of clay used or whether you use the pore sealing method (I'm sorry I don't know the english technical term of "closing clay pores", in italian is turapori) I just wanted to share this with you.
Hi, I'm new to ceramics and know nothing so I'm sorry for what's probably a stupid question. Does salt glaze taste salty? Like, if I made a pit fired cup and salt glazed it would that impact the taste of the coffee? I tried googling it but didn't have much luck which leads me to believe it's a dumb question that normal people wouldn't ask. Or that it's so obvious everyone but me already knows.
@@AncientPottery Hey, thank you for the reply. I watched that video and then about a million more that night. New favorite channel. I replied to this but I don't know why it didn't post. Might have missed the blue arrow or something. Sorry about that. I'm surprised I haven't came across one about pipes yet. Like smoking tobacco pipes. Have you done one and I just haven't found it yet? The back catalog is huge. I'm not a smoker but I collect pipes for some weird reason. Making my own clays was what brought me here in the first place and you captured and expanded my interest far beyond. So thank you for that.
I used several different clays for this project. I dig my own clay from nature so it is hard to characterize them other than to describe their colors (yellow clay, red clay, grey clay, etc).
@@andreholmes3949 the point is to keep the temp below the boiling point which could cause the pot to spall. So in Celsius that would mean below 100 degrees.
@@AncientPottery thank you. I’m wanting to get into pottery and don’t want to invest in a kiln starting off so I’ve been watching some of your videos. I thought I noticed you using Celsius more for measuring temp but that seemed warm so I thought to ask instead of assuming. The reply is greatly appreciated however
i saw another video where you were testing the waterproofing methods? and recall you just kinda dumping coals/chips directly overtop the 4 bowls! So this leaves me confused now seeing the whole *keep the pottery from touching the coals* thing 😢
I was under the impression that if air got trapped in the clay that heat would cause the air to expand and that is what caused my pots to explode in the fire.
I’ve had four successful firings in my backyard thanks to the information you share in your videos and I’m preheating now to burn a couple of coil & scrape ollas today. 🤞This channel is a treasure! Thanks, Andy!
Great to hear! Keep it up
i love your yt name ^•^
Andy, maybe you could use one of those metal tripod with chains concoctions that hold pots over a fire to pre-heat some bottoms.
Yes that would work
I am running on four hours of sleep. I had a brain fart; I read that title as, "you can fire pottery without heat". I think I'll go for a nap after I watch this video.

Too bad about the broken pots but it good that you show them. It's just the reality of firing. Beautiful red!
Thanks Wes. Yes, it is definitely a part of the process, learn from the mistake and move on.
Success and failure. Every failure is a data point for success.
Beautiful decorated pots, Andy.
So true. Thanks
Primitive pottery teaches you the philosophy of loss. I am used to having so much breakage that I started to make some pottery tools out of them and also chamotte by grinding them in a mortar. Those tempered with chamotte seem to come out better in fire than those tempered with sand. Also here in northern Sweden you don't have access to sand in winter: the soil is frozen under deep layers of snow.
Rule number 1 is to not become attached to your creation until after the firing.

For much of the spring and summer we were under outdoor fire bans because of forest fire risk, but fires in stoves with stove pipes and spark guards are not subject to those bans. I would also think with a wood stove I should have more control the temperature by adjusting the amount of fuel, air supply, and chimney damper. Old wood stoves are easy to come by up here, as insurance companies ‘encourage’ people to upgrade to newer, certified stoves.
If I am understanding, this technique would not be good for "store bought" clay?
It can be done with store bought clays, check out this video ua-cam.com/video/n1zwTqlu4GI/v-deo.htmlsi=2d2zaCexLF-68sqa
make a windbreak to tame the gusts
Not sure that would work.
Love Your videos ❤
I’ve been experimenting with a metal trash can with charcoal. I drilled holes in the bottom of the can to let in more air to get the coals hot. I’ve had mixed, but encouraging results. I’ve had some very good hard ceramic results. Even my failures gave a sort of subpar terracotta. I’m still working out my process. I live in a very wet area of the Pacific Northwest, so the process shown here, firing on the open ground, isn’t practical for me.
So the pots the broke during the firing what do you do with them?
grind them up and use for temper, you will want to add more temper to your clay next time to prevent breakage.
Can I do the same thing in my woodstove, do you think? I've been watching your videos and trying to learn enough to start making pottery.
Probably. Make a few clay objects that you won't miss if they explode, dry them thoroughly, and place them in different parts of the stove. You might also try altering the amount of fuel that you are burning. It might be necessary to gradually add more fuel rather than a bunch at once. I am curious to learn of your results if you decide to try it out.
Thanks. I think I'll put it on my Winter list. I heat only with wood so I like to multitask with the fire. @@Kargoneth
I do know some people who fire in a wood stove but I have never tried it so can't provide any tips.
Thank you. I'm going to try it, and the good thing is, I have less than zero chance of ruining any kind of artistic or practical creation. Winters are long and how much damage could I do? (Just kidding, Universe. I am truly at your mercy.) 😁@@AncientPottery
To avoid explosions it could be useful to put broken terracotta bits over pieces that you'll fire
That will only protect against thermal shock, this kind of explosion is caused by moisture, not thermal shock and the broken pottery will not protect against that.
@@AncientPottery I'm sure of your experience in the field, I don't think you need lessons. By moisture do you mean interleaving water? Because it goes away from the piece over 200° c.
I use a method that I learned from a wild ceramist friend of mine, his name is Aquilino Antonio Rodriguez Santana, he lives in the Canary Islands.
He keeps the pieces on the embers from 150° to 400°, only after 400° does he stake the wood, like you did at minute 03:35
He rarely has breakups.
I am aware that there are many other variables, such as the type of clay used or whether you use the pore sealing method (I'm sorry I don't know the english technical term of "closing clay pores", in italian is turapori)
I just wanted to share this with you.
Can you put glaze n them and it still work???
Hi, I'm new to ceramics and know nothing so I'm sorry for what's probably a stupid question. Does salt glaze taste salty? Like, if I made a pit fired cup and salt glazed it would that impact the taste of the coffee? I tried googling it but didn't have much luck which leads me to believe it's a dumb question that normal people wouldn't ask. Or that it's so obvious everyone but me already knows.
I don't do glaze so you are asking the wrong person. See this video ua-cam.com/video/V5eiGaFdeuw/v-deo.htmlsi=NUF7pMt6-t9rJT-u
@@AncientPottery Hey, thank you for the reply. I watched that video and then about a million more that night. New favorite channel. I replied to this but I don't know why it didn't post. Might have missed the blue arrow or something. Sorry about that. I'm surprised I haven't came across one about pipes yet. Like smoking tobacco pipes. Have you done one and I just haven't found it yet? The back catalog is huge. I'm not a smoker but I collect pipes for some weird reason. Making my own clays was what brought me here in the first place and you captured and expanded my interest far beyond. So thank you for that.
@@sethcarson5212 I am also not a smoker and for that reason have never made a pipe or a pipe video. Many people do make them though.
I really love your channel. Thanks so much.
Thanks for watching!
Can we store wet process tempered clay for longer duration ?
Some clays will grow mold or start to stink if mixed and allowed to sit around too long. But it varies a lot by clay so try it and see what happens.
What were the 2 types of clay that you used?
I used several different clays for this project. I dig my own clay from nature so it is hard to characterize them other than to describe their colors (yellow clay, red clay, grey clay, etc).
A little Kintsugi action with the broken pieces, maybe?
Was the oven preheat at 200 degrees Celsius or Fahrenheit. I’m assuming Celsius
@@andreholmes3949 I’m American. All ovens in America are in Fahrenheit
@@andreholmes3949 the point is to keep the temp below the boiling point which could cause the pot to spall. So in Celsius that would mean below 100 degrees.
@@AncientPottery thank you. I’m wanting to get into pottery and don’t want to invest in a kiln starting off so I’ve been watching some of your videos. I thought I noticed you using Celsius more for measuring temp but that seemed warm so I thought to ask instead of assuming. The reply is greatly appreciated however
How long does each step usually takes?
It varies a lot based on all the variables.
Hi Andy, is it possible to make the firing on a metal foil if the soil is too wet ? I've seena lot of video but never this way. Thanks.
It sounds reasonable but because I live in Arizona I have never had to try that
@@AncientPottery Thanks Andy, from the french Alps !
i saw another video where you were testing the waterproofing methods? and recall you just kinda dumping coals/chips directly overtop the 4 bowls! So this leaves me confused now seeing the whole *keep the pottery from touching the coals* thing 😢
The fuel can touch the pottery
@@AncientPottery ok so it *can* but maybe it's not *ideal*? i just remember seeing where creating space is what ya were goin for 😌
@@ginasaltina a lot depends on the results you are going for
Can you bisk fire your pottery like that?
Oh man!
How much time did you lose in those two broken pots?
That would kill me!
You have to tough out the losses, they are a part of the process.
I was under the impression that if air got trapped in the clay that heat would cause the air to expand and that is what caused my pots to explode in the fire.
That is an old wise tale. It is moisture that causes breakage, not air.
Watch this video where that myth is busted ua-cam.com/video/--d6usmwW1g/v-deo.htmlsi=xZzmE8mfivq3g9Nj
I checked out that UA-cam. Thanks for that. I am wiser now.
A fire in the southwest? Dude, hope the fireman hall approved that! A gust of wind…….😂anyway, I love this. Thanks you for showing these
Couldn’t you “dry” in an oven before firing?
Nevermind, just got to that part 😬
What was that pop sound?
Exploding pottery
cool
What about glazing?
No, I never glaze, this is primitive, earthenware, you cannot glaze this without firing it a lot hotter.
@@AncientPottery Thanks for clarifying!
👍
❤
I think I missed a step as I bumped into the 🚒 and they put my fire out 😭
Yep I went to bit I see that now
