- In this video I'll show you how I build a brick kiln for pottery making.
I used the design from another RUclips Channel called @primitivetechnology9550 check out his channel for more kiln builds.
To learn more about how to make pottery, visit my website higherperspective.art where I share useful tips, tricks and insights on how to find, forage, process and use raw clay!

Thanks for watching!
Love how you were inspired
Wonder if I could use this style of oven for Mexican bread baking. Good result man! Always interested in seeing how these things get built up.
Thanks broseph! And if you ever make some bread with a kiln like this, make sure you record it so I can witness it with my own eyes lol.
I intend to make clay bricks at my home village to build my brick house, and other farm houses on my private customary land.
Iam fascinated by clay bricks material plentiful at home.
That is amazing! I hope to have a piece of land with abundant clay sometime in the future, but for now I have to forage mine haha.
Good luck with your endeavors!
Good times ahead.
Very good video!
thank you Evan!
Aaand, aaaand aaa, aanddd, aaaam, aaaam , annnnd aaaaa, aaaaam... Cool
Thank you!
This is super cool! Can this be used to make food safe pottery?
It depends on what you deem as safe. Many cultures around the world still use earthenware pots for cooking, gathering and boiling water and many other practices dealing with food. But in the ceramic and pottery community in first world countries there is a lot of debate on whether it is food safe or not. So I can't really say one way or the other, but definitely do some research and experimentation and come to your own conclusion, and let me know how it goes!
@@Higher_Perspective_Art thanks for a great reply, that makes a lot of sense. I saw on another DIY kiln video that the kiln was not for food safe pottery and didn't quite know why, for the reason you stated already- earthenware is used all over the world. Thank you, I'll do my research and see what I deem safe for myself.
It depends on the type of clay you use - like you said, if it’s earthenware then it will vitrify at temperatures around 1945 F. The issue is that in certain countries they are used to glass/plastic that can hold liquids that don’t seep but in other countries they only use burnished pottery for serving or cooking rather than long term storage. Pit firing needs to get to the right temperature and that requires time and plenty of combustibles, so the temperature continues to climb. The amount of pottery you have in the fit firing also affects total heatwork. The other problem you can run into is that the wild clay may contain harmful minerals like magnesium (gives it a rich dark brown or even dark purple color) among others that if they came into contact with acidic foods, would eventually leech into the food which could potentially adversely affect your health. You can get the wild clay analyzed and then you’d have to test the clay for shrinkage properties, plasticity and test fire several to determine the temperature it will vitrify (after firing you soak it in water then weigh it and compare it to the weight prior to soaking it in water). That is why the simple answer to the question is “no” to the general public but it doesn’t factor in knowledge of wild clay and chemical analysis, reaching vitrifying temperatures, etc.
@starrynight2218 very true, thanks for sharing!
Food safe depends on porosity I believe. Clay doesn't crystallize hard enough to be truly impervious unless you reach a very high temperature. I believe around 2800 degrees F. I could be wrong about the exact temp. But the elements don't melt together fully until a certain temperature.
Can you fire cone 6 ash glaze on this kiln???
You could, but the bricks themselves aren't rated that high so I would most likely destroy bricks in the process
Did you keep the top open? How do you feel about the results? What would you adjust?
I kept the top open and I think keeping it like that gives it hotter embers, but on the other hand you have to constantly keep feeding the kiln and its hard to keep up the demand when you dont have a lot of wood. And I think I would make a bigger fire box because I cant get enough fire wood underneath so I have to add it to the top. Hope this helps.
That’s useful to know about the firebox size. Any experiments with firing it to share?
@@Higher_Perspective_Art If you had used the mud mortar instead of dry-stacking the firebox (and maybe also overlapped each course of brick) do you think it would have been sturdy enough to build a taller firebox?
@@michaelstansell1001 I definitely think it would have been sturdy enough if I would have done those two things. I couldnt really overlap though because of the openings, or I just couldnt think of a way to do it. But doing both would definitely make it sturdy enough
Maybe cutting some bricks in half would have allowed you to overlap the layers@@Higher_Perspective_Art
How many bricks do you estimate you used?
I would say around 140 or so. I did give out the exact number on a comment when I still had the kiln, but Ive taken the kiln down and repurposed the bricks into other projects
Pleasedo a longer or a slow motion video
I suggest watching the Primitive Technology channel. He has more detailed and in depth videos on how to make kilns for firing bricks
Does it have to be elevated off the ground? What exactly has to be ground level?
Elevating it off the ground helps with a stronger draft. The firebox (the area that houses the wood) will be on ground level but will have two chamber.
One chamber (the ground chamber) is meant for the fallout of ash and charcoal that will be produced from the burning wood. This will make it easy to pull the ash and coal out. It will also leave more room for the fire to consume oxygen, as well as being able to pull that oxygen from underneath itself, creating a stronger updraft.
The second chamber of the firebox is specifically for holding the fuel (wood or other organics). The bigger the fire box, the hotter and longer you can run your kiln for.
Are those regular bricks? How well did they hold up to the heat?
Yes sir, regular red clay bricks. They're rated to 1800 I believe and most of my firings get around 1650-1700, but have gone up to 1800 before. My kiln is still here after almost a year, still works, I haven't covered it from the elements either. I do have a few cracked bricks and some cracks that need to be refilled with mud, but overall works great still. I'll most likely do a 1 year review on the kiln and then do a remodel since so many people enjoy the video.
@@Higher_Perspective_Art 😮 That is good to know! I have wanted to make a kiln on the cheap and this gives me inspiration. Thank you for the video.
Can you remember about how many bricks you ended up using ?
Hey Supernova, thanks for the question, it was around 130 bricks
@@Higher_Perspective_Art thanks man
Hii😀.
Perhaps a stupid question.
I’m from Denmark 🇩🇰,and doing c… in writing English.
Hope u understand
Can I use paving stones . Instead of bricks ?
Hey Susanne! That's definitely not a stupid question. From my experience It depends on how porous the pavers are. If they are very porous then they will do okay as a kiln, but they will be prone to cracking more than a brick kiln. If you have pavers that are very smooth and non porous, it will be dangerous to use them as the moisture in the pavers (if you are using it outside) will have a hard time dissipating all of the moisture before it gets to boiling temps, making mini steam explosions as the water expands into a gas.
How many °C can be produce for this kiln?
The highest I've read on my Infrared thermometer gun was mid 1800 F. I'm not sure how hot it can get seeing as I only fire for about 6-7 hours max. It could probably go much higher if you used bricks rated for 2200 F or higher and also used higher rated mortar. It would take away from the flexibility of moving it though and become more of a permanent structure.
Measure twice cut once….prep work makes it easier. You can drive some rebar into the corner bricks. I wouldn’t believe too much in the channel you reference
Thank you for the advice!

Are those bricks fireproof please?
The red clay bricks used were rated up to 1800f. Some cracked at this temp but most of them did not. Hope this helps
