Glazing in Microwave Kiln

[@adriennealine]

I am SO happy I found your channel! It's refreshing to find such a skilled person who knows exactly what they're talking about!

Hi Mike, I tried today with Duncan glazes and works perfectly. Firing them for 40 min. So, this MWK works really well with Eathernware Clay and low temperature glazes. Happy with the results😁. Thank you for sharing your knowledge👍

[@CaptMike]

I'm glad it worked out for you!

Wow didn’t think you could do this in a microwave oven thanks great video

[@ulvevin]

what is shelf paper? and how do i get it. this series is so helpful, thank you so much for sharing your wisdom!!

[@CaptMike]

Shelf paper is a material that is sugar based (usually) material that burns off and leaves a white nonstick material behind that inhibits the sticking of glass to the ceramic shelf. The shelf should also be treated with a non stick (for the most part) coating called kiln wash. Both can be found starting here: www.amazon.com/Bullseye-Shelf-Sheets-Fusing-Supplies/dp/B084KYRKZ8/ref=sr_1_2?crid=2FEXALOXS1HQ2&keywords=kiln+shelf+paper%5C&qid=1643418189&sprefix=kiln+shelf+paper+%2Caps%2C68&sr=8-2 and here: www.amazon.com/Fireworks-FW737A-1-Pound-Kiln-Wash/dp/B008D1OQGW/ref=sr_1_4?crid=1CJIRQ1Z75LQY&keywords=kiln+shelf+wash&qid=1643418247&sprefix=kiln+shelf+wash%2Caps%2C63&sr=8-4.

I watched the green ware firing, then the glaze firing. I’m amazed you an do this in a microwave oven. I had a huge Bailey’s high firing kiln for porcelain, years ago. Can you do porcelain in the microwave?

The temps might not get high enough, but use porceline clay and see if it looks as it should after firing.

Nice! I didnt know that you can glaze in a microwave! I was being sad because I don’t have money for a kiln, but this seems like something I can try now!

[@CaptMike]

Nicole, remember that low fire (cone 06) glazes work best for this. Also make sure your project is not too large to fit comfortably in the microwave kiln. Leave a little room all around and remember to use shelf paper or something between the piece and the kiln bottom. Have fun!

Where can I find this glaze? thanks!@@CaptMike

[@CaptMike]

@@HerdsandWheySoap this is a Duncan Crystal glaze. Cures at cone 06. Do a search for Duncan or just "crystal" glazes and you should get an idea where you can get it.

This is awesome I will update you when I'm able to afford the microwave kiln. I'm going to be using locally harvested clay aswell.

[@CaptMike]

You should be able to pick up a microwave kiln on Amazon for around $37 US (www.amazon.com/s?k=microwave+kiln&crid=2N1K899BA72K5&sprefix=microwave+kiln%2Caps%2C82&ref=nb_sb_noss_1). I use local clay all the time. Mine always fires to a red color, but depending where you live your clay may fire didfferently. Good luck!

[@MeghanMurphyOG]

I had my first successful microwave bisque firing today! Question: why the 3min increments vs nonstop? Especially at the glaze stage?

[@CaptMike]

I do it as a way to slowely increase the temps. To be honest, I have fired for a full 15 minutes for glaze with no problems, but there will be a few mishaps....happens to all of us!

Hey Mike! Thanks for these videos. Wondering if you only use low fire glaze in the micro kiln. I tried using Cone 6 and the color didn't turn out right.

[@Angelacreatesart]

Shelf paper is that a special type of paper?

[@CaptMike]

Yes, it is a type of paper made with a sugar binder. That is what you will smell burning off when you first use it. You can get it on Amazon. Start here:www.amazon.com/s?k=kiln+shelf+paper&crid=3RSQLBK7BOOX&sprefix=kiln+wshelf+%2Caps%2C94&ref=nb_sb_ss_ts-doa-p_2_12

This made me smile

[@TheWildPaw]

Hi I’m new to this and even though my pot glowed, the glaze didn’t melt. It’s a low fire underglaze so I wonder should I have left it longer? How will I know it’s ‘ready’? Thank you for such brilliant videos

[@CaptMike]

If the piece was glowing cherry red it should have glazed. If using a glaze that fires to a golss usually 15 to 20 minutes does the job.

[@TheWildPaw]

Thank you very much :) much appreciated!

[@janetmorris7628]

Hi, just wanted to know if that was a food grade clay glaze,and if not can you tell me if there are some you can recommend?

[@CaptMike]

As far as I know all ceramic clays are food grade. Once they are fired to bisque all the impurities should have burned out. Glazes are another matter. Make sure they are food safe if you are going to use the fired piece regularly.

[@laskoreef47]

Hi, this is great! I found 2 beautiful handmade santa mugs in a thrift store from the year 1949 and the artist forgot to glaze the bottom of one of the mugs where the date is and her name. I want to preserve the bottom of that mug. Can i just add some glaze on that mug and microwave it for about 5-6 minutes without the microwave kiln? I don't want to damage the rare antique but want to coat the bottom with something that will stay when i wash and microwave it with coffee. Do i need a microwave kiln for this small project?

[@CaptMike]

Since you are dealing with something old and maybe valuable, I would not try to glaze the bottom. You might try sprayinga little clear enamel on the bottom, but I could not say that would work. Almost no one glazes the bottom og their work. It is possible that waterproof ink was used. Just be careful with the cups and you should be OK

[@howlingwind1937]

Thank you for sharing, I really like the little bowl, is it big enough to make a tea cup, not a mug, a nice tea cup. Cheers from Australia!

[@CaptMike]

As long as the cup is no more than about 1.25 inches high it should be OK. The kilns are plenty wide enough for a cup.

[@silvigdesigns5952]

Hi Mike, thank you so much for this video. I want to create a clay mug, from the previous videos that I’ve been watching they suggest to let it air dry for about a week than add the glaze and than add to fire. Is that something I can do in my kitchen microwave with the microwave kiln?

[@CaptMike]

If the mug will fit in your microwave kiln it is possible. I suggest you let the mug dry, then bisque fire it, apply glaze after that and then fire the glaze. If you need more help just let me know.

[@janicerowlands9593]

Wow! Can you test earthenware ans stoneware glazes - does it give an idea of how they’ll come it in the electric kiln. There does not seem to be any temperature control

[@CaptMike]

A microwave kiln will only reach about 1700 F. This is not hot enough or mid to high fire glazes to mature; as far as I know.

[@jessieluce912]

What about a gold lustre overglaze? 😃

[@CaptMike]

I have not tried that. I will have to do a little reacearch and see how.

[@toristoltzfus4066]

Hello! I am new to the microwave Kiln and I'm starting out with the smaller size. Do you know how long I should leave something really small thats glazed in there for? Like less than an inch

[@CaptMike]

The smaller the item is the less time it should take to get it to temps. Go with the 3 minute intervals and check in between. When it get brigh red it should be done. Remember, this is a trial and error system,.. Be patient.

[@1originalhaley]

I love your channel, had to subscribe! Question about off gassing with the glazes...is that a concern using it in a microwave, in a small space?

Any kind of "burning off" in a small space could be a problem. My shop is aboyt 25 x 50 with 9 foot ceiling so no problem. If you have a porch, place your microwave out there and you will be OK.

Hi Mike. This is a great project. My wife is really excited about it. Could she fire small bisque dolls in the microwave kiln? Thanks so much. Bruce

Anything you can fit into the microwave kiln without touching the top or sides should fire to bisque just fine.

[@shirleeschnieder4261]

Thank you so much for all the info. Can’t wait to try this. What clay do you use please?

[@CaptMike]

Shirlee, you can use any type of ceramic clay or skip. Just make sure the clay body (item) is thoroughly dry before you add the heat. Most of the items I do in my microwave kiln are made of clay slip poured in plaster molds.

[@shirleeschnieder4261]

I guess I will have to try it without a plaster mold and hand form the clay. I Assume a low fire clay may be best. Thank you for the help.

Just make a small finger pot out of regular clay. It will work fine.

[@SarahSarah-je3vp]

Can I fire a pot in gas oven without a klin that you used in the microwave?

[@raeb7579]

Hi Capt! I am watching and rewatching these videos as my makes keep exploding. I made it through bisque first time then exploded with glaze, second time didn’t make it 3mins to bisque and same 3rd time. I have preheated all clay at 90’c (UK) for 30mins prior to trying for bisque. Any tips? I am also completely new so struggling with dry time, I have seen some say leave it a week and others able to bisque same day as make. Any drying time advice between make and bisque, then to glaze and glaze to fire? I just want to stop the explosions 😂

[@CaptMike]

It's hard to say when I'm not present to see. I do know that if you use a regular kiln you can bisque clay that is not completely dry as the kiln heats up a lot slower. That is the problem with MWK's. Theu heat up very fast and if there is any voids or moisture present the piece is likely to blow up. I have had a few small pieces blow up, but not many and if I get to the glaze stage it usually works out fine. Try making your pieces thinner (for bowls). solid pieces tend to be more problematic.

About how long does it take to cool? In the regular kiln I wait at least 8 hours...do you have wait that long with the microwave kiln, as well? I'm so excited to try this! Thank you!!

[@CaptMike]

As a rule, I let the kiln sit about 30 minutes with the MW door open, then I place a 1/4 piece of ceramic under the lip of the kiln and let that sit for about 30 minutes. Usually that is enough time so that you can remove the kiln and place a thicker piece of ceramics under the edge. Usually it take about 1 1/2 hours to cool enought to remove the top of the kiln completely. I have rushed this somewhat and cooled in less time. It just depends on how much of a hurry you are in. I have never had a piece of ceramic crack no matter how hot it was when I removed it....think Raku.

Fired clay is what is used for glass molds. Just make sue the mold does not have undercuts and is prepared properly. Slumping or draping is no problem, but I have had some problems firing the glass to hot. Approach whatever you are attempting slowly until you find the right temp.

Hi, Mike. My microwave kiln works really well for bisque firing, but not for glazing, no changes in the colour. It was firing 35 min in a microwave 700watts with underglaze Mayco. My microwave kiln reach until 900°C Do you have any idea why i do not have results with the glaze? Thank you for sharing your videos, very interesting.

Alexandra, when I made this video I did not measure the temps. I used a Duncan coe 06 glaze, CR853 I think. I have since experimented with how hot a MWK will get ad find they can reach maybe 2000 degrees F. Most cone 06 glazes mature at around 1830F, but will sometimes work at around 1700f. See if your MW will push your kiln to around 955C. Maybe try another glaze, Duncan for instance. I know this will work, just have not tried all makes of glaze. Let me know how it works out for you.

One more question for your creative mind, Capt Mike- is it necessary for me to kiln wash my new kiln?

[@CaptMike]

@@drusmith243 It is always a good idea to put a coat or two on any kiln surface that will be used for firing. I prep mine with 3 coats of lin wash and also use shelf paper. Remember, the floor of these kilns ar not as robust as a regular kiln shelf and can use all the help they can get!

It’s food safe?

[@CaptMike]

If you glaze says "food safe" it will be OK.

Hi, I have another question :) I actually finally got a microwave kiln, but was wondering if I can just use it in my kitchen microwave, or is that dangerous? As in, fumes, resedue, dust that would contaminate my microwave and therefor would make it not food safe?

[@CaptMike]

It is recommended that you not use your kitchen microwave for the microwave kiln. There is some dust, fumes from the shelf paper burning off and maybe other things. Just be safe.

Hi Capt Mike i need help

[@AlegriaPeace]

Im glazing a pipe with crystalline glaze and the insulating sheet below got toasted and the bottom part of the microwave kiln too, what happened?

[@cookncrack5334]

Is it a normal microwave

[@CaptMike]

Yes, I have 1500 watt and a 600 watt and both work fine.

How much is the microwave kiln in Nigeria's Maria.

[@CaptMike]

I have no idea, but you can buy a 700 watt from amazon for about $50. Google $50 us into your currency and see what you get.

I would.

Hi Mike, some of my glazes bubble in the kiln, while others turn out well. Why do you think some pieces bubble and breakup and others don’t? I fire everything for 15 minutes in the microwave kiln?

[@CaptMike]

My best guess would be that the clay was not completely dry and as it fired gass was trying to escape. Maybe firing the piece over again will remove the bubbles.

[@Cocopoodle]

I'd like to try making a glazed band style ring in a microwave kiln. However, I'm not sure how to keep it from sticking to the bottom of the kiln since the entire ring will be glazed. Is there something I can use to accomplish this? Would microwave kiln paper be an option?

[@CaptMike]

I'm sure something could be rigged up, but I think the glaze would puddle somewhat where the glaze meets the paper. It would be worth a try though.

[@sunnyislandstudio1173]

where can we get that ceramic pot from?

[@CaptMike]

I made a mold for my pots by casting plaster around a small glass bowl. I think I have a video on that somewhere.

[@laurenblythe7707]

How long does it usually take to cool?

[@CaptMike]

It's hard to generlize. It depends on the size of the object and the material. I would guess that a cup sized object would take about an hour.

[@laurenblythe7707]

@@CaptMike gotcha, thank you so much! Do I let it cool covered or uncovered? If it cools too quickly (uncovered) will it crack?

[@CaptMike]

@@laurenblythe7707 What I do is cool in stages. As soon as the firing is complete I place a 1/4 inch piece of tile under the top and let it sit. After about 30 minutes I increase the height of the crack to 1/2 inch or so. After the piece has cooled about 45 minutes I remove the top and let it finish cooling. Most of the time ceramics will not crack if cooled rapidly. Think about Raku where the ceramic is removed, red hot and placed in a chamber.

Is this safe to do in my home microwave?

[@CaptMike]

If you clean your microwave properly after a kiln firing I don't see were there would be a problem. I make popcorn in my microwave all the time.

Hi Mike I was hoping to make porcelain jewellery in the microwave kiln, I don’t use glaze would I bisque first then put back in to high fire, thanks ?

[@CaptMike]

Karen, porcelain is fired to over 2000 F. My microwave kilns only fire to about 1500 F or so. If you are firing using porcelain clay you could try and fire a small piece for an extended time, say 20 minutes or so at 3 minute intervals and see if it turns out translucent like porcelain does. If you are looking for a "white" glossy finish you could simply bisque in the Microwave oven and glaze with either white or clear. Hope this helps a little.

[@רחלידובינובסקי]

How do you know when its ready? And for how long do you let it cool?

[@CaptMike]

It's all a guess! I usuall find it takes about 15 minutes to heat the glaze up enough to mature and that is for a low fire glaze. Keep check on the piece in the kiln and when it glows bright red let it cool and see if it is glazed. It all depends on the glaze and your microwave.

[@altoobaateliert]

Is it normal home microwave??

[@CaptMike]

Yes, I a couple of different ones, from 600 watts to 1500 watts. Both will work.

[@blueskyalldayeveryday]

Hi Captain Mike. I keep having issues with the glaze bubbling up. Do you think it could be because of the high heat? I put it on for 15 min (after heating it up slowly on lower wattage for 2x3 min). And when you do the 3 min increments do you let it sit for a while before going for another 3 mins or do you just quickly check on it? I’m so disappointed because it works great for bisque firing but I just keep failing with the glaze. I also make sure it’s completely dry before glaze firing.

[@CaptMike]

I do not wait between zaps and I have never had problems with glaze bubbling up. Are you letting the glaze dry completely?

[@blueskyalldayeveryday]

@@CaptMike That's good to know. Yes, I let it dry for up to 3 days when I was testing. I suspect my clay may not be fully bisque fired? I am just testing this so we shall see.

[@CaptMike]

@@blueskyalldayeveryday If you are using at least a low fire ceramic clay body and a compatable ceramic glaze, moisture is the only thing I can think of. Let me know when you get through testing.

[@fernkitten]

what is shelf paper?

[@caringiscool4941]

sir can you make a list link of the materials?

[@CaptMike]

You can use any ceramic clay for the vessel and In this case I used a cone 06 Duncan glaze.
