- www.paragonweb.com Fire raku pottery in a microwave kiln. (You will need the Paragon MagicFuse firing chamber, which is inserted into a microwave oven.) Demonstrated by John Toki (co-author of Hands in Clay) and Ben Belknap of Leslies Ceramics. The video was shot in John's Berkeley, California home by Arnold Howard of Paragon Industries. Please note: The clay must be bone dry before firing it in the MagicFuse. Pre-dry the clay before both the bisque and the glaze firing. The video explains how to pre-dry the clay. Drying is essential before firing it in the MagicFuse.

I AM AMAZED! even if you can only do small things, its perfect for people who don't have the facilities for small projects. would be great for ceramic jewelry and figures
what is the best clay to us for the mold. Can you use Sculptey? Great tutorial, Thanks for sharing.
Oh my God, im very happy with that tutorial, because in short time you show a lot. i want to learn make ceramic, and i was making some searching to see how much cost a kiln oven , but when i saw the prices, i was in shock, is a lot of money, and i didn't know yet about ceramic, but with your tutorial i was in shock because i have a little kiln like that for fusing glass, but some time i was curiosity to know if that can work to fire ceramic, and its work, im very, very happy, God bless you so much for that video. i want to make ceramic beads, because 10 years ago i bought a book about ceramic beads, and the book is very interesting, so i have the book on a cabinet for all those years and know i want to learn to make ceramic beads. thanks so much, and very sorry about my english, i don't know to much. thanks.
thank you so much, but the important here is that you understand me a least a little bed. did you speak spanish? where you come from?
really, thanks for telling me.im happy for that, because i feel more confortable.
I'm from Southern California and took 3 1/2 years of German and no Spanish even though in my business, real estate, it would have proved to have been indispensable. When you wrote "I'm from Alaska" it made me laugh. When I grew up we had one black kid in our elementary school, Nathan Cotton, and I was in love with the only Spanish looking girl, Pillar Hannigan. All the rest of the children, we were all Caucasian. Things have really changed.
i looked up and the guy was different. freaked me out!
No. It's the same guy after microwaving
John Toki and an employee from Leslie Ceramics did the demo. John’s presentation was extemporaneous, captured in a single take. I believe we shot the video in 2010.
Hello could you please tell me what music you use for your intro?
What size and wattage microwave is recommended for efficient raku firing time? thanks
Thanks for this video, I want to try this soon! Are there specific clay bodies that you have to use like low fire clays, or can you even use porcelain? And also, any specific glazes?
+Arnold Howard Why not ramp the process up and down slowly using the levels from one to ten?
what kind of glaze did you use?
Why is the second fire only 15 minutes like the first?..is that a low fire glaze? Is it able to fire cone 10 glazes?
that is absoulutly amazing that you can fire a peice in the microwave
this is cool but why are they firing a thimble
Only a tiny piece could survive the extreme temperature change.
Where can I buy this raku kiln placed into the microwave oven?
Can you underglaze before the bisque?
Hi I was wondering if the MagicFuse for glass is the same one for ceramics ?
+Arnold Howard So, it would be fine to fire clay in them ?
cool and simple technology. YES!
OMG - you shouldn't have shown me this... :) I have a regular electric kiln, but I never thought to do small raku pieces in a small coffee can. I don't drink coffee, but I collect cans for various crafts and I have several waiting to be used. Now you have me thinking about jewelry pieces...let's hope I don't burn my house down. :)
Same!!! 😊😊
The microwave kilns work extremely well and I haven't had any problems yet.
@@bossdog1480 Hiya, could I ask what type of clay and glaze you use please? I can't seem to figure it out
I can not find the kiln from paragon help please as I want to fire and glass small creatures and have no space for larger kiln
Nice job. Good to see videos from Leslies Ceramics, a great place for all things pottery and ceramics with knowledgable staff. One question, for the preheat in the oven to dry the clay, what temperature was used? A
I m wondering the same I I 200 Fahrenheit I was told by my friend but I m not sure
Excellent, thank you. Can you tell me what material the oven is made of? Since I see that they filled it up. I apologize for my translation in English. I speak Spanish. And ¿how many minutes did you leave it in the igloo oven ceramic?
excelente, gracias. Me puedes decir de qué material está hecho el horno? ya que veo que lo rellenaron arriba. Disculpa mi traducción en inglés. Yo hablo español. ¿Y cuantos minutos lo dejaste en el horno igloo con la cerámica

If you still need to know, the white material is fire brick. The grey lining is silicon carbide.
Hi, thanks for this video :). My English is not really good lol, i didn't understand wich temperature in the oven for dry pièces. during 30 mn but wich degrees ?? thanks :)
Thanks Arnold but it's not what i want to know. I want to know the temperature in thenormal oven for pre dry.....
@@Ycrt638 100C
does the vent whole have to be on the top or can you vent on the bottom with a shard of terracotta pottery?
The piece of terracotta would probably shatter due to the extremely fast temperature change.
where can i buy one...
this is freaking amazing!!!! i was looking into making a kiln and how much that would cost... granted this is only about a 3 inch space but i can only imagine how much this can help firing in general using waves to fire instead of firing for 8 hours
I am your second like after 7 years.😐🙂
@@ahsokatano5394 And I am now your third, and first
@@yaboi_jay2735 ☺️😹
j'aime beaucoup la poterie merçie pour votre demonstration
is it extactly the same hardness and quality as a ceramic done in a traditional kiln for like 10 hours.?
Probably not. Firing raku in the microwave kiln was an experiment. . . just to find out if it were possible.
Would it work for a mug sized pottery? His piece seems so small. I wonder how many extra minutes would be required for a mug?
We chose a small raku piece because it could withstand the extremely high speed. A mug would blow up unless you drastically reduced the power setting.
you have a point
So would you be able to glaze they item and make it food safe?
Yes
kick ass! awesome.
I appreciate that you have developed a way to fire pots in the microwave, but what's the point if you can only fire such small things?
Jewlery making
Interesting!
Do they still make this microwave kiln? It is hard to find.
Ebay from China. Probably $40. us.
Can you use mid fire clay in a microwave kiln?
I'd use cone 04 05 or 06 clay and a very low firing glaze as this only gets up to about 1400 F. Or that is what I'll be doing when I get my dedicated microwave (don't use your kitchen microwave there are fumes that you should avoid) also look for a microwave that doesn't have a safety heat sensor, it will shut off if the microwave thinks its getting too hot, thus will not let the kiln get hot enough to fire.
Hi - this is great for small pieces like jewelry components. :)
Is this a glass fusing kiln?
Yes. 99% of users fire glass jewelry in it.
cool!
great, i like to try it!! interesting video, thank you!
alguien lo puede traducir? Gracias
Please, help me! I don't know where I'm making a mistake :(
First works great, everything ok. Suddenly I started to have problems with the glaze. Baked, bubbles and a different color than before. I don't know what's going on? I shortened the time, I thinned the glaze, still nothing. Maybe a problem in the microwave?
If you start the firing from a hot kiln, the firing time should be shorter than if you start the firing in a cold kiln. You might get more consistent results if you reduce the power setting of your microwave oven and have a longer firing time.
@@arnoldhoward2076 Thank you for the answer. As I shortened the firing time, there were places where the glaze did not melt. As if it was unevenly heated? I will try to reduce the power of the stove. Thanks ❤
@@rozwojowa Some microwave ovens don’t heat evenly. Have you changed to a different one than you used during the successful firing?
Do they still sell these?
yes
You could look at it that way, or there are people who like making jewelry which would make it worth their while. I will be trying enameling in the next week with mine.
Looks like it can work for bisque and raku (both done usually at low temperatures), but this will not allow for impermeable ceramics (1200 degrees Celsius and above)
I was thinking the same but when he showed the kiln after he got it out the first time he said it was probably around 1800°.
Holly Land yeah 1800 degrees my a&$ no way
I've had mine glowing almost white. Some heat transfers to the microwave but most of it stays in the kiln.@@jeremystaehlin1292
What about firing something larger like a bellarmine jug in a microwave? I want to make a bellarmine jug.
In all seriousness its better just to make a bonfire kiln in your garden and then you can make pots that way.
The demonstration was only to show that a standard household microwave can get hot enough to do raku. I wouldn’t use the microwave for larger pots. The larger piece couldn’t survive the extreme heating rate.
Can I leave the kiln in the microwave to cool?
Yes
isn't the smoke toxic to have in a home though?!
What will you do with that tiny bowl?
You stash your weed in it. Quality over quantity. :D
i am a gnome and they gave it me to piss in --- it's akshully more effective than it looks out of focus and so close up to the camera .. etc ..
can you fire porcelain in a microwave kiln
I'm curious about the temperatures too
No. Raku was used because it’s more forgiving than porcelain.
@@lovv.profile We didn’t check the temperature.
I want that you make a video ,making a beads with the technique. what is sawdust for raku, what thats mean?
oh ok. by curiosity i saw a video about raku technique, and i like the way that look, sorry about my english i didn't know to much. but thanks so much to respond my answer. God bless you
why they're so sad?
If you take that kiln out without the lid being secured and it's 1200 degrees, what would happen if that lid tilted off? Wouldn't you suffer terrible burns?!
You have to be very careful. Use safety gloves and glasses. Always. Actually, the outside of the kiln can be handled without gloves, but they should be worn anyway.
Not if you don't want to drop it because it's too hot. Safety first. 😁😁@@arnoldhoward2076
i bet that would melt metal for casting
All My Paranoid Mind Heard Was....
Pottery Piece: Small Bit Of Water Left Inside Because Of Glaze.
Microwave And House: *+BOOM!!!!+*
I Think Its Safe To Say Ill Do This OUTSIDE. Like Id Just Buy A Simple Microwave....Keep It Out On The Back Porch In A Tote. And Use THAT When I Want To Fire Up That Kiln And Keep A Bucket Of Water Near By. Cause....No Way....Im In An Apartment With A Way Small Kitchen. That Is WAY Too Much Of A Death Hazard To Be Inside Here. I Honestly Dont Even Think I Could Use That Since I Wanna Make My Own Semi-Japanese Styled Matcha Tea Bowls. And Whats The Point Of The Fire Can? Is THAT Neccessary To Set This Clay? Cause That Burned Style Is NOT What Im Aiming For....
for a minute i thought you where serious
you should use welders glasses. shouldnt look directly at that white hot heat.
yeah this is great if you want to make pottery for ants
Ha ha you made my day! 😀😜
:D but if u are a lil artist like meh and u want to make lil statues for frens it's perfect. I like gifting (bc i'm not good at talking about gratefulness)
its 2 am here, and your coment just cracked me up laughing hard :)
That was so funny made cry
dude, isn't that a recirculating vent hood? Blowing those fumes right back into your hairdo! Sweet kiln though.
So, let me get this straight; 30 minutes to dry 15 minutes to bisque, 30 minutes to cool, 5 minutes to glaze, 30 minutes to dry, 15 minutes to fire, 10 minutes in the reduction, & presumably a few minutes to cool. 2 hours & 15 minutes total.
I could set up, fire, & tear down a full sized raku kiln in that time, & have a dozen full sized pieces, and not have a can fire inside my house. P.S. the fan on the microwave just recirculates air back into the room. It doesn't vent or filter fumes out.
Not to reply to a comment from eleven years ago but this is pretty obviously for people that don't already own their own full sized kilns...
Or jewelry pieces...
maybe upside down
Pottery for ants! :O
he seems nervous
The presentation was extemporaneous and shot in a single take.
Ha, ha. Very good guys. Yes, Raku WILL explode if it's not 100% dry before bisque-ing.
I was a little unsure of why you put your finished sake cup into the burning paper. The finish, I know, but wouldn't it look just as good with a nice shiny glaze? I realize this is an old video and you may not still be doing this.
I put a raw egg on a saucer and covered it with a coffee cup and then placed it in the microwave on high. After a few moments of watching M TV an explosion occured and violently the microwave door gaveway. Eggs and ceramic flew through the apartment, I felt like a squirrel being blasted by a small game load from a 12 gauge shotgun. The glass table was cracked in half.
for sure that wee ball of fired clay would look way dinky on any high class mantlepiece and was definitely worth the five tons of carbon in emissions it created to produce.
I have the raku piece from the demo. It does look very small on a shelf! Actually, the piece required only a minuscule amount of electricity.
This is very dangerous. Do NOT do this indoors in your kitchen. Ceramics causes toxic fumes and you don't want to be breathing that in and eating out of the same appliance. Cool idea for a garage workshop and a secondary microwave. Wear goggles to protect your eyes from the light inside the kiln, and a respirator if you're working with raku. Do the research and you'll see what I mean. :)
The piece that we fired was about 1 1/4” wide. It was so tiny that there was no concern about fumes or dust.
The safety concern would be from exploding clay because of the extremely fast firing rate. The clay was heavily grogged and forgiving, though.
@@arnoldhoward2076 When dealing with toxic chemicals its a good idea to play it safe. You can make a personal choice not to take those measures but as someone instructing the public and representing a company/product, you should have done better. Thanks.
For some reason this video saddened me . All that heritage , mystery and skill , of process being an integral part of the aesthetic seems to have become meaningless .
You telling me a rice fired this pot?
