Вставка
- Опубліковано 7 лип 2024
- In this video I will show you how to make your own ash glaze. And it's actually a very special ash glaze - because I will be using the left over ashes I get from pitfire.
I will show you everything from cleaning and filtering af ash, how to mix the glaze, adjust it, glazing your pots, fire them and how it all ends up.
The recipe I use in this video is:
1/3 Ash (575g )
1/3 Nepheline Syenite
1/3 Quartz

That was fascinating! I will be processing ash from my wood stove as soon as it gets a little warmer. Your tutorial was just what I needed. I love the simplicity of the recipe, and it is great that I can have 1/3 of my glaze from a byproduct I already have. Thanks so much!
Thanks :-)
This was an interesting and inspiring video. I'm sure it showed up in my feed because I saved some clay from digging post holes. I worked hard to get it out might as well see if I can do anything with it.
Found a great ancient pottery channel. The clay is still drip drying or perhaps it's called maturing, I know nothing about this. I'm a bit of a junk artist and the idea of making pottery glaze from waste ashes and maybe using the clay from my post holes. That's almost too good to be true. I'm off to watch more of your content.
Thanks a lot :-)
Beautiful results, very generously shared. Thank you so much.
Thanks. Glad you enjoyed it :-)
Thank you for taking the time. I learn so much from your videos 😊🙏✨
Thanks. Good to hear 🙏
It's wonderful to hear the Joy in your voice as you're unloading the kiln. Beautiful pieces. Thank you for the video.
Thanks. Glad you enjoyed it :-)
ur so cool! Im starting my journey with glazes and this will be one of my first experiment! thank you for your passion
Thanks and good luck on your journey
That gold and blue are killer!
Thankyou for ANOTHER fabulously entertaining and informative film. Loving your channel
Thank you so much :-)
My favorite combo is ash and temmoku gold, and floating blue over white. Bravo
:-)
Very interesting - I've often wondered how to process ash glaze -thank you
Thanks :-)
I am behind using ash from the barrel firerings. I loved some of the results on the rims with the other glazes. Can't wait to see it with the ability to melt at a lower temp. Yeah!
Good to hear :-)
Just found your channel via YT autoplay, Mikkel, and I'm so very pleased about that! What a fantastically detailed view into your world, plus the joy in your voice during the kiln unloading is dangerously infectious! 😂
Subscribed as I've absolutely no doubt I'm about to learn a great deal from you 😊
Best wishes from Caithness, Scotland 🏴
Thank you so much your kind words. And welcome :-)
Outstanding information in this video! I thoroughly enjoyed this. And the results at the end were wonderful!
Thank you very much for all this detailed information. Very generous of you. I look forward to trying this
for myself. That floating blue with the Temmeku gold is a real winner. Thank you!
Thank you so much for the kind eord ❤️🤪
This is exactly what I was looking for. Thanks for sharing the info.
Thanks. Glad you like it 🙏❤️
I love the ash glaze. It looks like wood fire from a cone 6 electric kiln. Brilliant!
Thanks. Yes, it does gove it sort of a wood fired feel ❤️
Thank you Michel. Beautiful pots and glazing. Ester from Australia.
Glad you like them!
Thanks for the video! Here's a tip for adding limited water - use a sponge. Put it in the water first. Then you squeeze it slightly above your tube and add a drop or two to get the desired weight. I use a sponge for painters, it's on a wooden stick and has round shape.
Thanks :-)
Amazing work Mikkel! Was such fun watching your work. Lots of love from Istanbul ❤
Thank you so much! :-)
Thanks for the very informative video, I have just got a big bucket of ash from pit fire 🔥 I’m looking forward to testing it 👍
Thanks 🙏
Fascinating. The temmoku seems to glow.
Thanks - yes, it does :-)
This VDO is absolutely wonderfull and very well explained Thank for 😍
Most welcome 😊
Thank you so much for such magnificent video!!
Thanks 🙏
Oh, just found my way to your UA-cam channel and found your ash glaze recipe, thx 😊
My pleasure 😊
I’d love number 13 as a bonsai pot 😱😱😱
Thanks. Could work :-)
This is exactly for what I was searching
Good to hear :-)
very informative tutorial , good work
Than you 🙏
Thank you I have enjoyed your Journey and that is because you are so enthusiastic. Excellent entertainment 😀
Thanks :-)
Excellent how to video well done.
Thank you 🙏
I'm about to see the pots and I'm excited. And I'm not even there. 😂
Good :-)
Very nice ❤
Many many thanks
Do luv the music ,and strangely I can still hear you (:
Still here cant wait see this
(: thanks learned so much
Thanks :-)
I luv the them all ,will enjoy doing ash (: Thanks for sharing
fantastic
Thank you so much 😀
I love being surprised by the scraps of metal that end up in the ashes in my kiln.
All sorts of things can end up there :-)
Mikkel, my question to you is about your choice of the number in your specific gravity calculation. When should that number change and when or why would other ratios and or other ingredients or additives affect your desire for greater or lesser weight/ density? beautiful work ❤
It depends on the kind of glaze and application. If sprayed in have to be a bit thinner. Some glazes need a thick layer - and a thicker glaze, som a thin layer. It all depends on the glaze. A SG around 1.40 to 1.45 is often a good starting point
Very nice… did you dip the pieces or sponge them on? I would love to see a video of how you apply the glazes… thanks so much 🌸
Thanks. I think I dipped these ones.
4:57 "theres always lots of shit left in there"
im dyin
But there is :-)
43:51 "i just want to add a few comments, to my *_ass_* glaze"
im dyin
Transskriptions are not always perfect :-)
Suggestion: Get a litter scoop to work out some of the biggest chunks might shave off some time?
Good idea! :-)
Bless 🙏🕉
Thanks for so good structured and clear information. Have been looking for ash glazing for a while and here it is 🎉
What is the lowest temperature of firing for this glaze recipe?
Thanks. I fire it to cone 6. Not sure it would melt out right much lower but could probably go up a couple of cones
Hi. Thanks for your reply to my question about the word”zenite “ . In the video, at approximately 10:47 you mention that you are going to use the same ingredients in the recipe that you “used before”. I just need clarification on what the ingredients are as I was unable to understand a few words. Thanks for your patience in this matter. I am really enjoying your videos. Very informative and entertaining as well .
Th recepie I use is in the description :-)
Loved this as I do have a lot of ash from pit firing. the only thing is that I have an electric so it is very important to not put salt into your pit fire as that salt will be in your ashes and do damage to your kiln. ( can you please make the music a bit softer as it was quite loud in this video. thank you, Mikkel) You had a lot of ash. I find it's very light and it would take a lot so I wish I had been keeping the ash from past firings, I'll keep it in a bucket from now on thanks to your great tutorial. (love your purple shirt, Mikkel!!! :-) I dip my glazes so could I dip in the glaze if I mix it to pouring cream? Looking in the kiln before it's ready to fire is exciting and amazing. I can't wait to see how it turns out. OH MY GOD, I have been writing parts of this comment as the video has been going and the results are gorgeous. Absolutely loved this video so thanks heaps.
All I can say it the glaze works well for me :-)
Thank you for demonstration wonderful experiment with ash glazing! How do you think if it will go well if colorize ready ash glaze within different pigments or commercial glazes? Will it change its grey color? And other question on what temperature you fire your pieces? I mean max t? Thank you a lot, you are cool potter master!
Thanks a lot :-)
I never did, but I assume you can mix in stains or oxides in the glaze to change the color. Just be aware, that some colorants also change how the glaze reacts. For example Cobalt makes it more runny.
This glaze actually gives a very nice green color when applied on top of some of my other glazes. I used it (although not quite enough) on my recent Fermenting Crocks. There is a video about it here: ua-cam.com/video/IvSBMO1B0Jo/v-deo.html
Thanks for this great video.. How much ferro frit do you suggest adding?
Thanks :-) I have not made it with frits
I wondered if the pots at the bottom so I'm not sure it got to temperature down there and it might be good to have some cones in to see what work was done by the kiln before you changed the formula for the ash glaze
This is a very new quality kiln. It fires very even
Beautiful work want i can use alternative to feldspar plz
Thanks :-)
You probably need a completely different recipe. You can find many on Glazy.org or in books dedicated to ash glazes. I just use this because it works well for me
24:00 a trick that I've seen before, might ve a little less of a hassle for you, people use those big plastic syringes with a ml count on the side. they tare the scale for the weight of the syringe and then fill it to the 100ml mark then measure the SG. its just much easier to handle a syringe rather than that tube of yours because it already has the measurements off the bat and it's easier to add/remove substance
something like this: images.app.goo.gl/vMNbn6rtyfK1U3Fe9
I know but I far prefer the tube :-)
Thank you for this great video. Could you please let mit know the recepy of the ashglaze, I could not understand it becaus of the music or mask. Thank‘s a lot.
Thank you :-)
It is in the description below the video
The recipe I use in this video is:
1/3 Ash (575g )
1/3 Nepheline Syenite
1/3 Quartz
Thanks for this video. Is it possible to know which floating Blue recipe you use? Do you think it could be possible to add oxyde directly in the hash glaze?
The one I use is close to the one OldForge have a recipe for, with Manganese instead of RIO. Adding pur oxide - not in a wash may be too much. But try :-)
Hello, which cone is this fired in?
And what's the recipe for your other favorite glazes that you talk about in the video?
Cone 6
You can find variations of most of the glazes I use at Glazy.org
Great video! What was the temperature in the electric kiln for the glaze? Perhaps it is in the video. But I didn't see it 😅
Thanks - I glaze fire to sort of a cone 6. So it's set to 1220 C with a very short hold. So it may actually be a little bit above cone 6 in the end :-)
Beautiful work. I have question did the ash glaze make pottery waterproof (I have 0 experience in ash glaze)
Yes, if your ash glaze is applied thick enough and fully melt it will be as water proof as any other glaze. But I mostly use it on top of other glazes to add some variations to colors.
To measure specific gravity I have a 50mL syringe which I tare on the scales. Then I draw up 50mL of glaze and weigh it. Say this glaze weighs 70g then 100mL would be 140g and so SG=1.4
I know some use that method. I like the one I use and find it more precise. But both can be used :-)
Hi Mikkel, I was wondering are you able to make an ash glaze with just silica and ashes? I've heard of using clay into the glaze, but when I tried the 50/50 ash and clay, the glaze did not come out the way I liked, so I saw this video, but I'm not sure where I can get the third component mentioned in the video.
I am not 100% sure :-)
Pottery supply store should have all you need. I use BSZ in Germany and Scarva in Irland.
Did you ever find a way of doing it without the need to purchase exotic additives? I want to make a glaze using only what I can source locally, directly from nature. I don't even care about how it looks in the end; just wanting a way to make the pottery waterproof (I'm making vessels to store water in, so want to avoid even a slow leech).
You can spray the Ash Glaze on pots, it gives them a toasty look. See Simon Leach, however he didn't know how to mix the Temouka Glaze which is my favourite. Absolutely beautiful. I like Gas Firing. I don't really enjoy this method of pitfire., I feel sorry for the pots, they look like they have been murdered.😮❤
There are many ways to do pottery.
thanks a lot! I had a question though, i dont have access to feldspar or nepheline, nor do i have quartz. I do have some sand and my stoneware which are both high in silica, what if i mixed some calcium carbonate, the sand and ash and some clay for binding, made it a slurry, and used that? Would it be a viable low fire glaze?
Thanks. I have no idea if that would work :-)
I think ur Calcium carbonate would to lime when reduced and that could be an issue. It’d react with water, potentially explode the pot. Idk, try a sample.
@@dingodog5677 ah, I see, ill try a small piece of cracked bisque, if it works, great. Otherwise I'll use some Terra sig- instead
Have you ever used crushed and powdered eggshell in any of your slip mixtures? Just curious how it would react during firing.
No, but I used it in pitfire. Not much reaction though
Hi , can I make any glaze on clay or it should be stoneware ?
A glaze have to fit the clay you are using. This one is made for stoneware. It may, or may not, work on some porcelain. You will either have to calculate or test that
Hi Mikkel, another great video.... but please don't play the music so loud on the soundtrack... it's very distracting.. thank you
Which part do you mean?
@@deMibPottery the beginning few minutes..., it got better further into the video,, . Thanks again
It's my daughter playing music in the garden. Not possible to change :-)
i liked the music
In my opinion, the music is not necessary when you are speaking. I only want to concentrate on your voice and what you are saying. The music at the end when you are showing the pictures of your pots is nice. I especially liked the bowl with the floating blue and the ash glaze on the rim. Really, I loved the way all of the pots turned out! Very good work!!!
Definitely some beautiful potery. But it seems to me as you open up the kiel to your surprise of color mix of what was fired was GOK (God Only Knows) the outcome.
I was indeed happily surprised :-)
I was told there is allot of salt in ash, and if you wash it a few times it helps
Some wash it, some dont. I dont :-)
Great video! Can you tell me the recipe for the floating blue. Thank you
Thanks :-)
I use a variation of this: glazy.org/recipes/77013
@@deMibPottery thank you so much
Hello l have a old backyard furnace l am thinking to make it into a wood fired pottery kiln.. l am guessing the highest temperature would be glowing Orange?
Would these glazes work? Or ls the temperature too low ?
Thankyou for your time ❤
Thanks. This ash glaze needs at least 1200 c to melt. Not sure you would reach that
@@deMibPottery thankyou for your reply.
is the second ingredient "Nepheline syenite"? i couldn't hear it very well. thank you for the great video ;)
Yes, correct
What cone are you firing at or is this for just for wood firing
I fire this at cone 6, electric oxidation
Hello nice video i just wanted to ask are those bowl bisque fired already and are they burnish? Or Is this a raw glazing process?
Thanks :-)
Yes, they have been bisque fired first. No burnishing. Just thrown and trimmed.
Hi, what is the third material yiu used? Ash, quartz and....?
It's in the description :-)
The recipe I use in this video is:
1/3 Ash (575g )
1/3 Nepheline Syenite
1/3 Quartz
i get the steel out with the magnet of an old stereo speaker. the charcoal pieces remaining in the sieve are good as coal.
Great ideas. Thanks :-)
Hi what was the white stuff mixed with the ashes please?
The recipe is in the description :-)
The recipe I use in this video is:
1/3 Ash (575g )
1/3 Nepheline Syenite
1/3 Quartz
What cone did the firing go to?
Cone 6
The chemical of ash is salt, clean the fire ash and filter you will have crystals you can put in glaze, what do you think of spagyeric ash for medicine, i use it to make tinctures?
Some wash the ash - some don't. You can do it both ways. I don't :-)
I do not know spagyeric ash for medicine
@@deMibPottery I guess the difference is washed for the salt for medicine, tinctures, I never heard of not washing, I make medicine but love the vessel so why I’m here.
Oh no Mikkel! Where is the big bowl with ash glaze on the wavy rim? :-( I am as excited and happy as you were when the pots and bowls came awesomely well! Just a couple of questions, was the white at the bottom of the bowls came from the floating blue or Heath A2 white? Also did you make the Tenmoku Gold with John Britt's recipe and perhaps will you demonstrate this recipe, pls? Many thanks!
Thanks :-)
The white is the Heath A2.
Yes, its John Britts version - the one with lots of RIO
@@deMibPottery The one with 11.24 RIO?
Yes
@@deMibPottery Thank you a for your tutorial and Happy Teacher's Day!!
Hi there new sub here! I'm also new to pottery. Where can I get that floating blue glaze and the temmoku gold? I'm in Canada 🇨🇦
I do not think you can buy them. You will have to mix them yourself. Recipies can be found at glazy.org
Hi Mikkel, you used 1/3 ash, 1/3 quartz and 1/3 what else ? I must use the translatier, sometimes it said wrong words Thank for your fantastics videos
You can see it in the description :-)
@@deMibPottery thanks I think it could be feldespato, bye
🙏🙏🙏🙏
:-)
I thought of the 3134 before you said it to lower the melting temp. LOL
There are lots of options to adjust this base glaze but it works well for me as is :-)
Can you use ash from a Raku fire can?
Probably yes. Try :-)
45:55 i think if you only applied the blue glaze to one side on top of the ash glaze you could make it look like water on a beach.
Thanks. Maybe :-)
Can i glaze earthware clay with ash glaze
I think so. I never work in earthenware. But you will have to adjust your recipe to the lower fire temperature
I'll like to know the temperature of the klin for this ash glace
I fire all my glazes to cone 6 (so approx 1220 C top temp with a 15 minute hold)
@@deMibPottery grazie mille
It would be great if you’d give the recipe in the description
Good idea. I just added it to the description. It is:
1/3 Ash (575g )
1/3 Nepheline Syenite
1/3 Quartz
@@deMibPottery wonderful, thank you
no le entendi el tercer ingrediente . ceniza, nepheline syenite y el otro no lo entendi
The recipe is in the description :-)
The recipe I use in this video is:

What is the zenith called. Thanks
Not sure what you mean?
@@deMibPottery sorry but I couldn’t understand what was said. I thought you called it more than zenith? Not even sure if zenith is the right word. I think it was an ingredient in the ash glaze or was it something you put in or on the pot before you put on the foil. Thanks.
How name ceramics ceameculs
Not sure what you mean?
What is A2 white , Heath A2 white?
Yes
A good video Mikkel but the Music is not neccessary in the background especially with singing as it interferes with trying to hear you😊
Thanks. My daughter was in the garden that day enjoying herself - and yes, she played music. Thats just how it is :-)
Hola, soy un abismo en la cerámica primitiva, y por favor ayúdame, lo que quiero preparar un revestimiento de metal para cerámica, tengo el dinero para comprar tintes de esmalte,
I am sorry, I do not understand your language :-)
@@deMibPottery You,,, yes, language,,,, speak,,,
Your throwing is good, so stop murdering the pots. Choose natural colours and your floating blue is beautiful 😻
I do my best but taste is subjective :-)
Please add ingredients quantity ?
I did. Read the description :-)
there is no sound
I have sound.
I have sound too
on mine there’s a speaker icon with a line through it you have to click on to turn the sound on.
I'm not sure if the music is just playing at your home or if you added it later as a background soundtrack. No objections to the song, but using it while you are talking makes it difficult to hear what you are saying for people with hearing issues. I just wanted to share that point of view, in case you hadn't considered it. I really enjoyed the video and appreciate you sharing your knowledge and experience. :-) Have a great day!
I know. My daugter was in the garden that day playing music. Only noticed after I did the video but decided to share anyway :-)
Love the musik but not when you speak..
My daughter was in the garden that day playing around. We all have to be here :-)
HABLA MUCHO ,TRATE DE HABLAR MENOS Y HACER MAS.Y NBRE LOS COMPUESTOS EN CASTELLANO
Thanks, but I try to explain what I do :-)
Due to your lack of enunciation I had some real problems understanding you. Common word where not much of a problem, but other things were impossible. Like I could figure out that "ass" was ash, and "quats" was quarts. But the other white stuff you put in I have no idea what you said since it not something I'm familiar with. Subtitles did not help at all, it just made it worse.
The recipe is in the description :-)
The video is too long. You can explain it in 15 minutes.
I do slow video. Thats how my channel is :-)
@@deMibPottery I understand you, this is your style, but there is so much information to learn that time is very valuable.
If you are talking you should not be playing music at all. We want too hear what you are saying not your choice of elevator music.
Its my daughter enjoying time in the garden in the background so could not avoid it on this one :-)
Why music in the background
Because my daughter was enjoying herself in the sunny garde
