*Hey guys! My mind is blown at what this little device can do :) Let me know if you got any ideas from these experiments, and if you liked what you saw? Thanks for watching, subscribing, and I'll see you in 10 days when we get back in town with the videos on how to make it!! :D*
Great job Grant! I need one of these in my shop. I should have warned you that plaster can act as an oxidizer in thermite reactions if you happen to try to cast REALLY hot metals into it. Look into making green sand from bentonite powder for better copper/steel casting
Haha sounds impossible but my furnace did just that. My furnace started reacting with aluminium and burned down leaving me with couple of calcium droplets 😢😢
Some quick links to a few of the materials I used: [✓] Lantern battery: amzn.to/2cgnKxN [✓] Forstner Bit: amzn.to/2c1Ja3V [✓] 3/8 Drill bit: amzn.to/2cgl6rL
Davey Hi I'm not certain thats how it works, but if it is, fine. I will say that aluminum is conductive though, so it seems like you would never be able to conductively isolate them
MetallicReg I see, well, maybe just "temporarily' permanently install them then hah. Install them on something you can get them out of, to replace or adjust them. The hand-held leads just seem like an inconvenience that could be fixed
If it melton stone, kind of yes, any metal. Pure Tungsten melts at 3.4k ˚C, while stone melts between 1.5k and 4k, depending of the silica composition of the stone. (While it is most usually at 1.5k, i'll place my bets in yes, it can melt tungsten)
I think it would be really cool if you gathered all your melting equipment (ie. This, solar oven, spot welder, metal foundery, etc.) and just had a long video (like 10 min) with just melting stuff, like trying to make glass, and maybe trying to make the lava again and put it into ingots. That would be so cool! I hope you take this into consideration, or even just look at this. Hope to see it soon!
Absolutely insane! It blows my mind that something like this isn't widely used. I mean you made lava...LAVA....with nothing more than household stuff! I'm somehow convinced that that power output is like nothing before and could benefit mankind. I however don't know if scaling it would be practical or even feasible.
Well he did not discovered fire for christ's sake,ever heard of plasma cutters? Im not saying that this is not nice but technology behind this exists for at least 10 years,he simply reproduce it form household trash-and for that he has my respect. Althou every fool can see that those cables are too thin for long lasting use,something that he should work on. Not many of his projects last long,they are not industrial quality and lifetime tools-i know its for show and throw away. I still like his channel,i would like to see microwave arch welder that will last more than a week.he should focus more on durability. As for commercials i hope he wont make same mistake like Kipkay did(make a video and more time is commercial than video itself) ,it cost him a lot of subscribers and his videos are boring same old stuff,like he is making them for money only.
I watch these videos, and I'm like,"How is it he hasn't been killed yet?" He plays with flammable hydrogen, liquid nitrogen, eats dry ice, make a stick welder out of a microwave, and melts rocks into lava using flashlight batteries.
The molten rocks are a glassy substance just like the refractory ceramic brick, because of this, they stick and melt together. if you instead exclusively melt metals in your furnace, then there wont be nearly as much damage.
Oh my god, this is the thing... this is the video that changed my life :)) I was struggling with an 800W electrical furnase and could barely melt aluminum if i left it for hours. God i'm so happy i found your channel! Thanks Grant!!!! You rock!
NecroBanana jet fuel is not mentioned anywhere in the video or previous comments. and in regard to jet fuel, steel beams and 9/11, the beams would not need to melt, the impact force was enough to make the twin towers fall. fires caused from burning jet fuel could have caused other objects/ materials to catch fire. if there were gas pipes in the world trade centers [quite likely for heating and such] this could have 'melted steel beams'
Look,it is as simple as this: I am going to have to set aside a portion of my life specifically to view "The King of Random" videos.I get fantastic entertainment,loads of tips and tricks that are actually quite useful and practicable,and I am even beginning to learn to think "outside the box".It beats watching rubbish soaps on telly and thats for sure.Many thanks Grant and please keep them coming.
I'm currently in the middle of building the welder with the intention of building this also. I WILL be building this to see if I can retrofit it to my coffee can forge and use it for blacksmithing. I'm also curious if I can use it to heat smaller sections of a larger piece.
Dan Broomhead ... Why would you even want to do that? You want fine control and a large homogenous heat mass for heating up metal for blacksmithing, not instant enormous heat.
Depending on how closely you watch your metal I believe you could have fine control, plus you could heat up sections of the larger piece since you don't need to heat the entire work piece when forging. You also don't need a "large" heat mass, you can forge using a simple coffee can forge heated with propane. I know several pro smiths that use an oxy/acetylene torch for almost everything besides the heavy stuff. Also, electricity is much cheaper than propane or coal. I think you could get the finer control needed for the majority of forging by just watching what you're doing. If you can do that then the "instant enormous heat" could/would help you be more efficient with your time.
Dan Broomhead To work a piece in general you're heating a large portion of the piece. Something that would be difficult with this method. You can, but you'd be raping the earth to use a mediocre fuel to accomplish something that requires you design around the downsides of propane. Electricity, and electrodes. There are reasons electricity isn't commonly used for forging metal as opposed to casting it. It would also make it far easier to make mistakes, be more finicky, and require additional gear, and everyone makes occasional mistakes.
Mr.chang cooler Well think about this, practicly EVERYTHING in the world wears down with use (phones, food,...) so yes it wears down with use, as you can notice that the furnace doesnt look as smooth when used, even tho it can handle the heat
darwin poop Yes, everything wears down, but I want to know how quickly it wore down. Will I have to buy and make more furnaces in a day? a week? a month?
Thanks bro, you sold me on electrical over waste oil for the furnace. Now I gotta scale one up so I can process larger scrap. You've got a new subscriber.
So the rods burn away after a period. How long and what about contaminating the metal? Do you wear dark or welders goggles? Safety info would be useful. I am guessing for each type of metal you need a separate arc chamber? How long will the bricks last? I know from the other vids you run it from 240v using separate circuits in yur house. Here I would likely burn the house down [[really poorly done wiring in a ten year old house.]] So what results using a single 110v? Questions, questions! ;)
What causes most of the rods to burn away is the oxygen in the air. As oxygen reacts with carbon - carbon monoxide is formed at first, wich then burns to carbon dioxide as it leaves the furnace (it doesn't affect the metal being molten). A small part also sublimates due to the extreme temperature in the arc, but even most of that will end up reacting with the air and go away as carbon dioxide. I havn't tried it my self so I know how long they last - but it shud not be to bad. Carbon rods can often be bought cheap from those who sell welding equipment, as they are sometimes used for cutting of metal.
Hey, quick idea for you with this project. Have you considered filling the holes inside the furnace with refractory cement to lose less material when you pour? I notice that the brick slowly seems to deteriorate after each use because it's so soft. Do you imagine refractory cement would help the inside hold up better?
Ohh my God! That's great! I'm a beginning welder from Poland and that stuff really inspired me to do such things. The best part is it's actually really cheap
As a kid I remember making arc lamps using 120 vac and a salt water ballast using two carbon rods. Any ac load wired in series will work, even two graphite pencils using a 15 watt bulb!
Good question. No damage at all if used for 3 minutes or less at a time. I didn't go much longer than that to smoke test it, so it's still in perfect condition. The carbon rods work for around 10 minutes before becoming so thin they need to be replaced.
1:20 ' Surprisingly, the outside is still cool enough that i can pick it up bare handed..' HOW ? I mean, i watched mythbusters doing that but can anyone explain me why doesnt that burn your hand. Since it is in the melting point, shouldnt it be extremely high that can burn anything that touched to it ?
The inside is incredibly hot, but firebrick is designed to not transmit heat, so it would require absolutely massive levels of heat to make the entire brick heat up.
Fun Fact - If you've watched VSauce, you can actually argue that the brick is pretty hot on its own, but due to the rate of which heat is transfered from the brick to your hand is horribly slow, the brick can feel pretty cold (or, at least not scorching hot)
I build this too, but with a little inlay to make the area smaller and smaller holes to reduce the amount of heat radiating into the surroundings. The 200 amps from a welding transformer are now making the tiny chamber so hot that it melts gravel in 17 seconds.
Most of the functional, expensive parts of his projects came from the trash (i.e. microwave transformers for the welder, big screen lens for the death ray). They would be pretty expensive if you had to buy them, though.
+Paul Austin Wattage is all in charging, ie VxA. He's using low voltage, high amperage, so the wattage is moderate. Higher voltage would make the melt faster or handle larger quantities, but he doesn't want that, it's fast enough as it is.
How long would it still be lava instead of cooling down? Also, how would you control the lava and prevent it from spreading? Is that possible? If you know please tell me, it sounds really interesting.
It would be all theoretical but this might work: Keep the torch heating the rocks to keep it molten. Set up a timer or thermometer to keep it at the right temperature. There must be a transparent material that can withstand the temperatures. You might need to wear a welding mask when its turned on but I think it might work. It was also meant as a joke. I wouldn't try it inside but maybe for a barbeque or something similar it would be pretty cool. :D
Yea, I agree. That's a pretty cool thought though. Do you think plexiglass could withstand that temperature? I'm not sure about that though. I'm pretty sure it's just used to withstand impact.
probably not but instead of a transparent material you could have mirrors that reflect the inside of the container out. PS just searched plexiglass would probably become a gas at the temperatures required. Its apparently 115 C so nothing near the required 700 to 1300 C.
Is it just me that thinks projects like these should be done outside? It seems like it could possibly burn your whole house down if youre not careful enough with that much heat.
Grant Thompson - "The King of Random" Sir Thompson, can you do a video how you do the welding machine with the battery thing? I don't know how you do that with a 6 volts battery. I was planning to create my own too so I can have money for my thesis in architecture(A side line). Thus inhaling it is dangerous? Thus it give you a cancer, if it does a need medicine that I can take to prevent the toxic from getting in my body?
VisayasMindanaoLuzon The battery and welder are separate things. All you get from the battery are the carbon rods. There is already a video on how to make the welder, or at least a version of it called the metal melter that he repurposes into a tack welder. The one shown in the video has two transformers rather than the one seen in the projects I mentioned.
not possible, because tungsten melting point is higher than carbon's sublimation point. And both much higher than what the firebrick can hold, so he would be splashing melted firebrick before that.
I would suggest refractory sand for future molds. Will open up a lot of possibilities for castings. Create a positive from plaster and then used a box to hold the sand and make a press with a bottle jack to force the impression into the sand as compactly as possible.
Eventually, the rods can reach about 6500 degrees before melting and tungsten melts at 6100 degrees, however, the electricity will have a harder and harder time passing through the rods as they heat up so it will take a very long time to get there.
The steel is sparking like that because it's actually burning. Not melting, but burning. Steel actually burns before it melts, meaning there is some loss when you smelt it.
I'll need to remember this video in a few months. A friend and I are planning to make a grappling launcher over the summer and we're gonna need a way to cast a custom steel hook
hey, can you try to step up your game a throw some diamonds in there, maybe to a kickstarter or something to buy them, or see how much gold you can get from hacking cpus on old computers and using that. (gold would be interesting simply because its gold, but diamonds would be even more interesting, since they have an insanly high melting point)
Hey K.O.R. I Love your Projects, it gives me a number of ideas for producing Projects of my own, even the processes that you show of how to make the make-shift foundries and the mini metal foundry are very helpful in making some of the things I want, right now I am working on a project for making a mini Tatara using the technique(s), Materials and stills you demonstrated on this and the last couple videos you posted so that I can make a small batch of Tamahagane ingots for Forging either my own Samurai Sword or making my own type(s) of Kukris and Karambits from scratch, Thank you for the ideas and the videos.
+Djordje Mihajlovic wrong... Tungsten's melting point is 3422C, while graphite's "melting point" is 4026C. Tho, graphite doesnt melt until you have 100 atmospheres of pressure. It will just evaporate or so.
Wow, I am really interested in seeing what his background is. Such dangerous diys that are explained very well. Easy enough that they seem repeatable, but with enough warnings so people (hopefully) don't set their house on fire.
Did you need to make a new furnace for each metal? It seems cleaning the arc furnace would be next to impossible after it cools. This has inspired me to dust off the ol' workbench, and attempt to copy your dangerous creation. Thank you for not repeating a thousand safety disclaimers. This is great work.
hey no a furnace can be used over and over again .normally if you use all the liquid,the only thing that will be left is the scraps witch dont stick the furnace ,you can just scrap it off ..
An added refinement would be to line it with refractory cement. The advantages of this are several: firstly, it'll keep water from infiltrating the brick. The last thing you need is an explosion. Secondly, it gives a smoother surface so you'll have less material loss, and make it easier to remove dross or other waste contaminating the next batch. Thirdly, it'll slow erosion of the brick - as you noted, it's rather subject to wear.
Awesome! This (but scaled up a little), will be my next project. I now have a furnace using heat resistance wire, that can get to 1300°C (enough to melt cast iron, but not steel - cast iron has a little lower melting point than pure iron or steel due to it's high carbon content).

Thank granty
will there be a time to replace your electrodes? they look alot different than newer
how long can you use that furnace
Jenildo Sation well as long as ya got a crucible (bottom of a fire extinguisher in this case) you're gonna be fine
I don't know why you are so happy aaa
Please try creating glass with your furnace, that would really amazing!
i was thinking that
Glass is difficult to do, if it cools unevenly / badly it can explode
There was a reason that glass making in Italy, was all moved to the island of Murano (so it wouldn't set fire to the city)
FedeKode its true
Yup :)
Seems like it would be more convenient to permanently install the electrodes and operate the furnace with a switch.
You have to touch the rods together then separate them a certain amount so they can't just be fixed in one place.
They get a bit shorter every time you use them. So you will need to adjust them anyway.
Davey Hi I'm not certain thats how it works, but if it is, fine. I will say that aluminum is conductive though, so it seems like you would never be able to conductively isolate them
MetallicReg I see, well, maybe just "temporarily' permanently install them then hah. Install them on something you can get them out of, to replace or adjust them. The hand-held leads just seem like an inconvenience that could be fixed
+Kakunapod They could melt your installation if you are not carefull - this will be a mess ;).

Makes me feel alive too Grant, this is one of my favorite videos. It's amazing what you can do with basic things around you and a little know how.
Any metal? Even tungsten?
Iridium reinforced tungsten steel?
Benny Kolesnikov That makes absolutely no sense.
Yes, any metal :)
Not tungsten you would have to heat it up to a little over 6000 degrees Fahrenheit
If it melton stone, kind of yes, any metal. Pure Tungsten melts at 3.4k ˚C, while stone melts between 1.5k and 4k, depending of the silica composition of the stone. (While it is most usually at 1.5k, i'll place my bets in yes, it can melt tungsten)
"Im not exactly sure but i think we just cooked up a batch of lava" 😂😂😂😂😂

As for commercials i hope he wont make same mistake like Kipkay did(make a video and more time is commercial than video itself) ,it cost him a lot of subscribers and his videos are boring same old stuff,like he is making them for money only.
You can melt most common rocks with a normal charcoal furnace that he made before.
spratsprat true, but they usually don't glow. The glowing is what makes melting rocks interesting
I wonder how many people didn't use gloves to handle the electrodes and are no longer here.
Because of the intense heat and/or electrocution ?
No one
You would be fine
The voltage is too low, it's fine to hold it with bare hands. I assume he used the gloves for temperature reasons.
It's not the voltage that kills, it's the current. You can die from a 41 V high current electricity.
I watch these videos, and I'm like,"How is it he hasn't been killed yet?" He plays with flammable hydrogen, liquid nitrogen, eats dry ice, make a stick welder out of a microwave, and melts rocks into lava using flashlight batteries.
he's careful and intelligent. things are only dangerous unless you're stupid...except percussion explosives, those are dangerous no matter what.
legionbunny no, if something is dangerous, its dangerous.
Atlas Slates danger is a matter of opinion based on the abilities of the individual
Toketildeath no, you might be safe 9999 times out of 10000, that doesnt make the danger any less real
that would make it .0001% Dangerous
How long does it takes before the furnace is broke down by the molten steel? With the liquified rocks it seemed really damaged.
I don’t know much but it probably is depends on the heat. So doing lower melting metal probably makes it last longer
The molten rocks are a glassy substance just like the refractory ceramic brick, because of this, they stick and melt together. if you instead exclusively melt metals in your furnace, then there wont be nearly as much damage.
last video: Im going to add this muffin to my metal collection.
next video: destroys it completly.
last video was a zinc muffin, this vid was an aluminum muffin
Oh my god, this is the thing... this is the video that changed my life :)) I was struggling with an 800W electrical furnase and could barely melt aluminum if i left it for hours. God i'm so happy i found your channel! Thanks Grant!!!! You rock!
1:39 meet jim, hes a very kind thing that noone cares about, nonmatter what he does it wont last😇
So it doesnt melt steel beams?

Its a bad conducter of heat
So its hot inside but not outside

Wow. I wonder how much money it takes to make all of your projects. Must be pretty expensive when you combine it all.
he makes way more money than he spends just by ad revenue
Most of the functional, expensive parts of his projects came from the trash (i.e. microwave transformers for the welder, big screen lens for the death ray). They would be pretty expensive if you had to buy them, though.
All the projects he does are pretty cheap actually. ;)
christian190400 plz tell me you're joking ... youtube add revenue is a joke
easthight they are meant to be cheap.... Durrr
would the plaster of paris/ sand mix from the foundry project be able to withstand those temps?
Andrew Martin I doubt it
Probably not recommended. The firebrick is like 6 dollars and more reliable.
Silent Skeleton where can one get a firebrick?
You can find them at lowes or online :o)

This is my new favorite channel, but i know if i try any of this i will give myself 3rd degree burns. You need to make a safety video
I was burnt by grease it hurts horribly I was wrapped up like a mummy
Nick Davis apparently burning to death is the most agonising way to die
uh i think itd be 4th degree if you got molten steel or lava on your hands
+livelife441 Just wear gloves with thermal insulation and electrical grounding
I was melting pewter and it sort of blew up and got metal on my hand and now I have a small but deep burn
I was getting sooooo happy and excited that my husband had to check on me. I can't wait to make my own.
Wow....your electricity meter must be running at like mach1 or something?
+Paul Austin Are you from Yorkshire??
+collinsm26 lol! No..not even close! 😁
+Paul Austin
Wattage is all in charging, ie VxA. He's using low voltage, high amperage, so the wattage is moderate. Higher voltage would make the melt faster or handle larger quantities, but he doesn't want that, it's fast enough as it is.
Paul Austin it isn’t using electricity it’s a chemical reaction
Is there anything else to use as a power source instead of a microwave?
xXNICKPLAYZXx I hope so
Arc welder
Kerbals
TrollFace Productions Waffles
TrollFace Productions a welder
Are the gloves the only thing insulating you from the arc?
+liam the great The voltage is so slow that it cant shock you. Its like touching battery
+Ben its the amps not volts that kills you
+Ben but if it's arcing between the carbon rods and had enough voltage to jump the gap then why not through your hand?
kylesenior If you watched the other video, he rewired the microwave oven from high voltage low amperage, to the other way around
+James Shand Yes, but on average your body has about 100,000 (100K) ohms of resistance. So you need about 20volts to go through the skin.
Miss you Grant ❤️
Thank God you didn't become a super villain.
r.i.p grand thompson.
Who else really wanted to see how the steel ingots turned out
me
I feel happy, thinking about future experiments & projects. Thank you.
Anyone else thinking of a desktop lava lamp? Literally :D
How long would it still be lava instead of cooling down? Also, how would you control the lava and prevent it from spreading? Is that possible? If you know please tell me, it sounds really interesting.
It would be all theoretical but this might work:
Keep the torch heating the rocks to keep it molten. Set up a timer or thermometer to keep it at the right temperature.
There must be a transparent material that can withstand the temperatures.
You might need to wear a welding mask when its turned on but I think it might work. It was also meant as a joke.
I wouldn't try it inside but maybe for a barbeque or something similar it would be pretty cool. :D
Yea, I agree. That's a pretty cool thought though. Do you think plexiglass could withstand that temperature? I'm not sure about that though. I'm pretty sure it's just used to withstand impact.
probably not but instead of a transparent material you could have mirrors that reflect the inside of the container out.
PS just searched plexiglass would probably become a gas at the temperatures required. Its apparently 115 C so nothing near the required 700 to 1300 C.
Hahah lol, I was way off. I think one way mirrors may work though :)

Is it just me that thinks projects like these should be done outside? It seems like it could possibly burn your whole house down if youre not careful enough with that much heat.
Solution: Be careful enough with that much heat. :)

Sir Thompson, can you do a video how you do the welding machine with the battery thing? I don't know how you do that with a 6 volts battery. I was planning to create my own too so I can have money for my thesis in architecture(A side line).
Thus inhaling it is dangerous? Thus it give you a cancer, if it does a need medicine that I can take to prevent the toxic from getting in my body?
VisayasMindanaoLuzon The battery and welder are separate things. All you get from the battery are the carbon rods.
There is already a video on how to make the welder, or at least a version of it called the metal melter that he repurposes into a tack welder. The one shown in the video has two transformers rather than the one seen in the projects I mentioned.
He has an fire proof work bench
very clever using the extremely bright light for transitions.
R.I.P our dear friend.
I'm interested if this could actually melt tungsten as it has the highest melting point of any element
It might be spitting out plasma, but i don't think the average joe with 2 Microwave transformers could melt tungsten.
C.Y.N.I.C.Union That's a stereotypical look. This thing is hella powerfull if it can melt stell within minutes
Maybe but u probably can't hold on to it so that long
not possible, because tungsten melting point is higher than carbon's sublimation point. And both much higher than what the firebrick can hold, so he would be splashing melted firebrick before that.
+Herkus Kaminskas Powerful* Steel*
I had to.
did anyone get the han solo reference?
yeah, that was really cool!
yes
Yup
i didnt get
Cody Maley i did
I would suggest refractory sand for future molds. Will open up a lot of possibilities for castings. Create a positive from plaster and then used a box to hold the sand and make a press with a bottle jack to force the impression into the sand as compactly as possible.
Watching in 2019 grieving his death
How did he pass? Hopefully not from breathing all these fumes..
watching in 2020 doing the same :(
At least he knew he contributed to people getting a real education, more than most teachers can claim
can you melt adamantium with that? wolverine would be pissed
adamantium cannot be re-melted
adamantium isn't real
Cool Guy Your not real
Core Tet
*BURN*!!!
The Krell would be more pissed because they invented it on Altair 4 (it's a Forbidden Planet thing).
can it melt tungsten
Sully Moe No. Tungsten has to be made using powder.
Sully Moe maybe
Probably
Eventually, the rods can reach about 6500 degrees before melting and tungsten melts at 6100 degrees, however, the electricity will have a harder and harder time passing through the rods as they heat up so it will take a very long time to get there.
There are plenty of ways to melt tungsten, they're just not commercially viable either because of cost or time.
I freaking love it. That's how it makes me feel. I just wish I had a bit more space and tools to make some of these things.
can it even do tungsten? also your voice is awesome
***** ummm, thats just a bunch of squares
It's donut emojis. Idrk why he put them there.
Donyea Mosley oh ok. makes a tiny bit more sense now. not much though xD
yeah it can melt any metal
***** is that donut emojis too?
R.I.P LEGEND🙏✊❤
I know his dead but what happened to him
3:20 one ring to rule them all lol
The steel is sparking like that because it's actually burning.
Not melting, but burning. Steel actually burns before it melts, meaning there is some loss when you smelt it.
is is possibles to make copper coins???
probably but you'd need a stamp or something. You could probably just do a small layer in the mini muffin thingy
You should make a huge penny

he beat me to it.
I'll need to remember this video in a few months. A friend and I are planning to make a grappling launcher over the summer and we're gonna need a way to cast a custom steel hook

hey, can you try to step up your game a throw some diamonds in there, maybe to a kickstarter or something to buy them, or see how much gold you can get from hacking cpus on old computers and using that.
(gold would be interesting simply because its gold, but diamonds would be even more interesting, since they have an insanly high melting point)
you just can't melt diamonds, you know.
s1nce yes you can. it just needs to be extreamly hot (5000 celsius)
It can't go that high (read description)
martinshoosterman Carbon rods like the ones used in this have a melting point of 3500 C so no you can't, in this furnace.
nukeboy27 in this one, you cannot, in general though of course you can. you can melt anything.
Hey K.O.R. I Love your Projects, it gives me a number of ideas for producing Projects of my own, even the processes that you show of how to make the make-shift foundries and the mini metal foundry are very helpful in making some of the things I want, right now I am working on a project for making a mini Tatara using the technique(s), Materials and stills you demonstrated on this and the last couple videos you posted so that I can make a small batch of Tamahagane ingots for Forging either my own Samurai Sword or making my own type(s) of Kukris and Karambits from scratch, Thank you for the ideas and the videos.

4:03 "it's worth it for your about to see, that's right you can't see anything" Bruh😂😂😂
How many of you guys ACTUALLY tried this?
Noah Duong I made the mini metal foundry, not the ARC one because I was afraid to mess up and end with my house on fire but still did it.
Noah Duong i tried it less than 2 days ago and ended up with a shiny aluminum bar. Next up is copper and pure iron bars.
Noah Duong going to make it soon
+CeeDee Player Good idea this thing actually just made lava
I did with a ark welder
but the question is will it melt tungsten (with a melting point of 6191 degrees Fahrenheit or 3422 degrees Celsius)?
Maybe if you use a version of this with all 8 electrodes simultaneously
i dont think it can do that, but i could be wrong (quote me on that haha). But Oxy-Acetylene torches should be able todo that. (in a vacuum??)
Reid Burke yes but youll need 480 vac and 4 transformers
No with graphite rods because the melting point of graphite i lower than tungsten...
+Djordje Mihajlovic wrong... Tungsten's melting point is 3422C, while graphite's "melting point" is 4026C. Tho, graphite doesnt melt until you have 100 atmospheres of pressure. It will just evaporate or so.
you should melt glass
That would make the glass stronger because glass is actually a very hard liquid, aka molten sand.
Colbeat 505 it ain't a liquid
It's a solid
Wow, I am really interested in seeing what his background is. Such dangerous diys that are explained very well. Easy enough that they seem repeatable, but with enough warnings so people (hopefully) don't set their house on fire.
What will happen if you drink lava?
You turn into a dinosaur
U try😆😆
it taste like hot suace
It'll just be a little spicy that's all. 😆
all your organs will evaporate instantly
I was suprised that it melt stone, that is so cool! I need to make one of there arc furnaces for myself! Or two, if I follow your instructions.
Did you need to make a new furnace for each metal? It seems cleaning the arc furnace would be next to impossible after it cools.
This has inspired me to dust off the ol' workbench, and attempt to copy your dangerous creation. Thank you for not repeating a thousand safety disclaimers. This is great work.
hey no a furnace can be used over and over again .normally if you use all the liquid,the only thing that will be left is the scraps witch dont stick the furnace ,you can just scrap it off ..
An added refinement would be to line it with refractory cement. The advantages of this are several: firstly, it'll keep water from infiltrating the brick. The last thing you need is an explosion. Secondly, it gives a smoother surface so you'll have less material loss, and make it easier to remove dross or other waste contaminating the next batch. Thirdly, it'll slow erosion of the brick - as you noted, it's rather subject to wear.
Alls I can see is how powerful the distraction from this sort of project can be
ずっときいていたい。ドラムスとベースのコンビネーションも工夫がされていて、最高。🤣🤣🤣
Awesome! This (but scaled up a little), will be my next project. I now have a furnace using heat resistance wire, that can get to 1300°C (enough to melt cast iron, but not steel - cast iron has a little lower melting point than pure iron or steel due to it's high carbon content).
I wish your videos were still like this
