How to Make Microwave Kilns (For glass fusing and Mold Burnout)

[@amandahugankiss4110]

took me way, way too long to notice your fancy machine was just a sideways microwave. i laughed so hard.

[@ShakeTheFuture]

Yes, I did not mention it in the video, since I already showed it in the first video "melt metals in the microwave". It can confuse people 😀

[@antoniopoll3377]

As a process engineer who has worked in the investment casting industry for almost 40 years, I am very impressed with your work.

[@ShakeTheFuture]

Thank You! You made my day. Glad to hear that people find useful/interesting the information shared in the video.

[@panther105]

I love how you offer many options for doing the same step in the process. Shows that you understand your audience and want everyone as possible to feel they can do it too... !!

[@ShakeTheFuture]

Thank You!

[@ShakeTheFuture]

This is the second part of the video. If you have not seen the first video ("Melt Metals in the Microwave"), you might want to check it out first. This was a 5-year journey of exploring alternative ways of metal casting. Turns out, you can do a lot with a microwave and a vacuum cleaner. This video was delayed over and over again for various reasons. I am pleased and relieved that it's finally finished. Thank you for your patience

[@lhinarizona6658]

Polishing in the small holes... I've been a silversmith for close to 50 years and for polishing inside small holes I use tooth picks in a rotary tool like Dremel or Foredom. Use with your favorite metal polish and it is cheap to replace when you break one. :)

[@madebyrasa]

and dip them in waterglass, then powder carbide. after they dry, it's sandpaper on a toothpick.

[@ShakeTheFuture]

That's interesting. I'll give it a try. Thank You!

[@TQV_4013]

I'm thinking that dentist tools could maybe work to polish the small holes...

[@mattwilliams3456]

Is vibratory polishing effective for things like this?

[@JosuRibeiro]

What about using a tumbler with very fine steel shavings?

[@youmebornfree]

I will "CAST" this dude as my right hand man during a zombie apocalypse. It's rare you feel like you are earning a degree while watching someone tinker in their apartment. This is KZbin University at its finest. Keep it up Mistro. I love how efficient you are in thought and action. You inspired, educated, and entertained the holy trifecta of social media. How did 182k people find you before me? Cheers.

[@sierraecho884]

Single best channel on metal casting on your balcony while wearing flip flops on the whole web. Joke aside, this channel is amazing, you are the only guy doing something like that and the efficiency is amazing.

[@sierraecho884]

I think this might be the single best video on KZbin to create a cheap kiln and establish a cheap process to cast metal parts. Kudos

[@ShakeTheFuture]

Thank You!

[@LincolnWorld]

I didn't even make it 5 minutes into the video before I thought, "I need to subscribe to this channel, now!" I will be watching this video many times over once I get all the stuff needed to start doing this. I knew about microwave kilns, and lost PLA casting, vacuum casting, etc, but I never realized how straightforward and actually doable it was in my own home. I've always sent stuff off to people that have the equipment. This video is very inspirational!

[@ShakeTheFuture]

Thanks! I am glad you found it useful!

[@EgonSorensen]

:-) Interesting topic, interesting comments? I always go see here before I watch; so many click baits now-a-days. Sure, gut feeling was correct - super content, and I'm subbed as well.. Thanks ShakeTheFuture, for sharing and caring

[@dogbones8149]

All DIYers and makers should aspire to be you. I feel like i can safely speak for all of us likers and commenters when I say your ingenuity is an inspiration to us all! Not to mention the fact that these techniques stand to make some of us 'ballin on a budget' folks a good bit of walking around money! Thank you for all of your hard work and experimentation! You are one of the giants whose shoulders we stand upon!

I just wished such well researched and informative videos were more common on KZbin. You earned my subscription!

[@ShakeTheFuture]

Thanks! I am glad you are joining the community.

[@MickTee2k]

​@@ShakeTheFuture You earned it! While I am a big fan of DIY, to me most of the kiln and furnace designs involve too much time, space, and effort when compared to the cost of the commercial offerings - that is, until now. Part of the issue for me is that finding the raw materials is difficult when you live in the tropics but that ceramic wool seems easy to get as it is light and transportable and its used in pizza ovens! But I have noticed there is a product called "Superwool" which seems a much easier/safer product to work with, but at a higher price. Do you have an opinion on it? Worth considering?

[@ShakeTheFuture]

@@MickTee2k I have never used it. It does look like much safer product to use. If I'll ever make more kilns, I might try it out. Cheers!

[@quarter42coralli]

I just made a silicon carbide crucible using the glass method. I made my own waterglass using the kitty litter and lye method (there are tons of videos about that), mixed it with silicon carbide, and it made a solid crucible. The glass cracked as expected during the process. I cooked the crucible in the microwave for 10 min with kaowool surrounding it, and my hi temp thermometer registered over 1800 degrees F (and the kaowool was not very well wrapped)! I'm a believer! I can't wait to make the kiln and the vacuum system. I have a backyard foundry furnace that works well, but not for small parts. This is a game changer for smaller detailed castings.

Nice video. For your issue with melting bubbles in copper, you can use many solutions. But most and not overpriced is adding some special salts into copper before melting. And second is using vibration / ultrasound after colling phase. Or both methods together for fine surface. Don't stop.

[@ShakeTheFuture]

Thanks for the tip. I will definitely explore some of these suggestions.

[@JosuRibeiro]

This video should have more views. I've dabble into metal casting using a gas furnace before and boy that was so fun. This seems like an easier, less noisy, and less dangerous way of doing the same thing.

[@C-M-E]

Cheap, simple and effective, my core trio for a DIY project! Even better with reusing common items, another similar trait to my own methods. Sometimes you (not you directly, just 'you' as interchangeable term) end up with a roundabout way of getting what you want, but when you shop for supplies at the thrift store, I'm okay with that. 👍 When you decide to scale up your casting devices, might I recommend going straight to a discarded water boiler body, shaping your kanthal element with all thread screw, and spending some of that 'big toy' money on a programmable PID.

[@ShakeTheFuture]

Thanks. I bought a PID controller a few years ago for possible future projects. So far, I have not used it. Cheers!

[@FullSpeed_only]

Have been waiting for the Sequel. Thank you very much. - In my Experience the Alkaline Silicate Solutions (Li, Na, K) bubble up when heated before it could dry completely. I guess it needs to dry and then has to be gently heated to remove the Water that is chemically bound. - The hardened Rings can be wetted before scraping to avoid the Dust in the Air. - Wetting the Fibre Wool on the Outside with Waterglass can replace the Capton. There the bubbling can even be positive. After the first Layer it won’t soak much in but stabilize the fragile Bubbles.

[@ShakeTheFuture]

Great info! Thank You!

[@FullSpeed_only]

@@ShakeTheFutureSorry, I missed the Part where you discuss the Waterglass on the Outside. Investigating what created the Hotspot would be interesting. I’m using bought Potassium Silicate Solution for my Experiments, but I’m yet to build a Microwave Kiln. If it can happen with pretty pure Solutions something is strange.

This is all amazing and thank you for documenting it so well! All of these alternative solutions and the one that blew my mind the most is using the thermoplastic as a workpiece holder/clamp

[@ShakeTheFuture]

Thanks Nick!

[@kentswan3230]

Absolutely fascinating. I watche the entire thing and was really impressed that you developed methods to cast parts with sufficiently high detail and seemingly enough dimensional accuracy to use for castings that will then be used as initial castings for precision machined parts. Also that there is actually a burnout-compliant material for resin printers.

[@ShakeTheFuture]

Thank You!

[@Microwavingmetal]

For using construction plaster, this came out great! The porosity can be caused by many things, but my guess is because you had had some sputtering and popping when you poured the metal, there may have been some resin left in the mold.

[@ShakeTheFuture]

Thanks! I actually think the sputtering was caused by too much heat or a reaction with plaster, but I might be wrong. Like you said, it could have been caused by many things. I have lots of learning to do. The reason I say this is because it's not the first time it has happened. I've done some lost PLA copper casting, and the same thing happened. Once I poured the copper cooler, it was not sputtering. The bad thing is there is no way for me to control the temperature of the metal. Sometimes, I wait for the metal to cool down, and it can cool down too much. I suppose I could get a better thermometer 🤔

[@otherlutris]

Pardon if this has been said a bunch of times in the comments: The power setting on your microwave is almost certainly duty cycling. It won't give as many options as the external interval timer, but it probably gets close. I think mine goes down to about 20%. It's also really handy for melting butter without having to pay constant attention. Though on watching longer, I'm not sure that my microwave can be set to run hours at a time! I get it now, if it's got a timer switch and you do duty cycle timing externally, it extends the time that the knob is on. Honestly pretty clever! thanks or going over the safety stuff, I was a bit worried for you in some of the parts where that's not shown, but you have put a lot of thought into this. Thanks for mentioning the earlier experiments and why you changed methods, too. That's really handy to know. A thought for drying things in the microwave: I think the microwaves themselves are stopped by the mesh, you could take the plastic cover off the front of the microwave and it would still be safe. If it's made into a door, then you could optionally have it closed (for retaining heat) or open (for venting moisture). Just triple check that I'm right and that layer is just to retain moisture and heat.

[@ShakeTheFuture]

Yes, indeed. Using a microwave on a low power setting would probably give similar results, but the timer would need to be topped up regularly. I can do the burnout without touching the microwave for approximately 4 hours. I doubt that many microwaves allow you to set the built-in timer for more than 60-99 minutes, but it's definitely an option. Cheers!

[@sevazinhogamer9521]

I finally melted something in my kiln right now. I used another method to make it because my silicon carbide has a higher grit and i couldnt mold it, so i put more water glass and i used 2 glass cups with different diameters and put it between them. I melted almost 1kg of bronze and copper, but something strange happened. I couldnt remove all the glass inside the kiln because it melted a little when i first baked it, it melted together with the copper and bronze but didnt mixed well, now the mix is more like a glass than a metal haha... I gonna melt it again with more metals to see what happens. The top of the kiln doesnt need to be something rigid, i discovered that a sheet of refractory fiber solve the problem with arcing and protect the microwave. Thank you soo much! I gonna try melting some harder metals like chromium, nickel and other misterious metals that people doesnt use. Update: i think im using too much my microwave, i melted my first kiln, and its is silicon carbide! I dont know if its real silicon carbide or aluminum oxide, i bought as silicon carbide, but it shouldnt melt no matter i did with it! I gonna try aplying a coat of tungsten outside of it or something else... Update 25/12: i did another crucible using like 50% SiC + water glass, 20% ZrSiO4, 20% graphite, 10% crucible mortar and hold it much better, but lost a lot of thermal efficiency because of zirconia, took like 30% more to melt the alloy. I need to find the perfect percentages now.

[@czconnoisseur354]

Excellent video and thank you for your hard work! I've been working on improving the strength of the silicon carbide bonding using different refractory materials added to the mix. I'm having trouble with some of these mixtures arcing through and melting the ceramic fiber mat!

[@ShakeTheFuture]

Thanks! Good luck with troubleshooting the arcing issue. Microwave kilns/metal melting is definitely more challenging, and it can take some trial and error to find suitable materials.

[@BlackDidThis]

I loved the many little easter eggs throughout... But it is the toilet brush in the fridge that I still can't get over :) Once again: FANTASTIC video. Very in depth and efficient. I would love to give the tips a try some time and see how replicating would develop on my side of the table. One question though... Does how course/fine the sand (that you add into the dental plaster) matter?

[@ShakeTheFuture]

Thanks! I use fine sand (0.1 - 0.6mm). My understanding is that fine grit sand is better for capturing detail, but coarse grit sand might produce stronger molds as well as make the mold more porous, which can be beneficial for burnout, gases, and vacuum. I am not a metal casting expert, so take it with a grain of salt 😆. What I can definitely confirm is that sand will make the molds stronger. Another thing to keep in mind is that not all "Plaster of Paris" brands are the same. I used to buy one brand of dental Plaster of Paris from a dental store, but then I noticed that there was an option to buy it without the bucket, only in a bag which is cheaper. So, I did. When it arrived, I noticed that it was made by a different company. Long story short, the molds were flaking during the burnout. It looked like there was paint peeling off the mold. So yeah, Plaster of Paris brands matter 😀

[@caseyjordan9513]

Wow this is an incredible video. Bravo

[@ShakeTheFuture]

[@trollface391]

you want you should try lost foam casting next...here is a trick... dissolve lots of foam in acetone untill you get "napalm" or jelly ... Pour the jelly into a mold and let it dry... Once the acetone evaporates you will end up with your object being casted with foam 😁😁😁 this trick actually helped me so much.... If you 3d print with foam...you can do lost foam casting without burning out the foam... Just dissolve it inside the mold

[@ShakeTheFuture]

Thank You! I might try it out one day.

[@beefan1596]

This is exactly what I've been looking for - an easy way to create foam molds. Lost ___ casting seems like the most appealing option for me, but I cannot afford a burnout oven, plus a furnace, plus a vacuum chamber, plus... etc. I do have a few questions: What exactly do you mean by "If you 3d print with foam"? I thought foam 3D printers weren't yet available for personal use (and what I've seen would not be effective for mold creation - too many gaps). And on the topic of 3D printers: if you poured your foam-acetone jelly into a 3D printed mold, would the acetone dissolve the PLA? Or would you need to create a separate mold out of silicone, using your 3D printed object as the master? I'd like to reiterate just how helpful your comment is to me. Pouring an acetone-foam mixture into a mold, dehydrating it, and using it as a method of lost foam casting is ingenious. I can also imagine the surface quality might be far greater than merely carving the foam with a hot wire.

[@MikeyRoofffff]

[@lukearts2954]

About sanding inside the holes, I think it would be interesting to see you discover various methods. Perhaps you can try using the polishing abrasive of tumblers, but use it in an ultrasonic cleaner. Or just use rope of natural fibers. You'd be surprised how abrasive normal rope can be.

[@Luke-Barrett]

I had a heart attack at 40:13 when the spider came down.

[@ShakeTheFuture]

[@joshsayler7110]

Amazing video on hobby starting in metal casting. @33:00 you're talking about timing switch, instead many microwaves have a 'Power Level' function which serves the same duty cycle 10% 'Power' is microwave on 1 minute, off ~5 minutes. Though at the end of the video you show that your microwave has only 35 min maximum timer.

[@ShakeTheFuture]

Thanks for the comment! I don't quite understand how you would change those power levels automatically. Sometimes, I do adjust the power of the microwave at the beginning of the burnout or at the end. Instead of running my microwave at 900w, I do it at 700w and then turn up the power later in the burnout process. I realized that there might be some confusion about the way the timer works. The 35-minute timer only 'runs out' or the rotary dial moves when the microwave is ON. It's not one of those timers that makes a clicking noise and keeps running even if the microwave is turned off. The 35-minute timer gives me approximately 4 hours and 5 minutes of burnout by using a 1/6 interval cycle. Because the microwave will turn ON for 1 minute and stay OFF for 6. Cheers!

The tiny holes of the ring can be cleaned with sand blasting but using Sodiumdihydrogencabonat beets or fine walnut shells granulate instead of sand.

[@samposey522]

To clean the tiny holes, try using an air powered spark plug cleaner. It's like a small canvas bag that holds blasting media (sand) and the air blows it around inside and out. You can rough polish it that way too with sodium bicarbonate (baking soda) as well.

[@ShakeTheFuture]

[@Marco_Onyxheart]

I've been having a lot of trouble with this. Especially with mold-making and burnout. I ordered some PCL filament which has a very low melting point. Haven't tried it yet. I find the kiln a bit dangerous so I'm thinking of cladding the inside of my microwave in fibre instead, so I don't have to take the kiln out. Or maybe I will just make donuts. That does seem like a good method.

[@ShakeTheFuture]

I was also considering trying lower melting point filaments out of curiosity. Figuring out the burnout schedule takes some trial and error, but once you have it... it works very well.

[@GiolliJoker]

Awesome video!!! I wonder if this kiln design could be used to heat treat steel, although I guess it would require some sort of separate thermocouples to get reliable temperature readings. But if you managed to melt cast iron and stainless steel in it, the potential seems to be there.

This is incredible. By any chance do you have the link to the printable squeeze bottle screw-on funnels at 45:23? I can't see it in the description.

[@ShakeTheFuture]

Thanks! I forgot to put it separately, now the link is in the description. Cheers!

For the burnt 'Captain' tape, Apply the initial binding tape with a gap and a sacrificial band that you can blowtorch to char, remove, replace

Thanks for the tip Rupert!

Thank You. I'll keep that in mind.

Crazy results for just DIY tools. Thanks for sharing your process and findings. What I didn’t understand 100% was how the vacuum works. Why doesn’t it suck the molten metal all the way into the vacuum cleaner?

The Blackbox Microwave Kiln uses an air cooled magnetron and is a standard format, computer controlled unit. In the states we cannot sell such a kiln without FDA approval and our units. They must be manufactured in an inspected within the manufacturing setting, in a facility and cannot leak microwaves. Even LG, GE, Samsung and other microwaves leak. I suggest a microwave detector to verify any industrial, commercial or household units. In your current format the sideways orientation may cause the top ring to heat first and, i suspect,, will always ground first, with the microwave guide being centered. It is surprising that your magnetron is still working after a few uses, however you must have access to a better supply of magnetrons.

Thanks for this gift my friend! There's so much useful info packed into this video, I'm probably gonna watch it at least twice. Perhaps using the vacuum to pull boric acid/kiln wash into the ceramic fibers may prolong their life?

Thanks for watching Drew!

Dremel tips for sanding fine holes, tumbler sanding is also an option.

Thank You!

Thank You!

Brilliant!!! What's the purpose of sanding/torching the ceramic blanket? Are you making an airtight ceramic shell to surround the blanket interior?

[@hakajiru264]

Thank you for openly sharing your knowledge! Have you tried searching/using industrial graphite rings for billet moulds? Would shorten the build process quite a bit if they are available and reasonably cheap.

[@ShakeTheFuture]

Thank You! I have only made my own rings/crucibles. I tried to use a bought graphite crucible, but it did not heat up. I also received some feedback from the viewers who bought silicon carbide crucibles, but they did not heat up. Cheers!
