WARNING:
Risk of electric shock, fire hazards, and toxic fumes depending on what material you're working with. Dust from refractory brick should never be inhaled, as it can damage lungs and cause long term respiratory challenges. This project can reach temperatures in excess of 3,000ºF (1,648ºC) which is well beyond the melting point of hobbyists. Caution, care and expert planning are required to mitigate risks. Have fun, but always think ahead, and remember that every project you try is at your own risk.

Project Inspired By:
This project was originally inspired by Theo Grey and his book, "Mad Science". After seeing the concept, I couldn't find any information anywhere on the internet or in libraries about arc furnace experiments, so I set out on my own to achieve these results.
Project History & More Info:
If you're wondering where you can get fire brick locally, try a quick Google search for “refractory materials” in your city. I called a couple of companies near me and asked if they'd sell to the general public. All of them said yes.
If you can't find anything locally, try searching major hardwares stores online. They usually have inventory online that they don't carry in the stores.
The insulating fire bricks I got were the 3” x 4.5” x 9” Alumina-Silicate Brick variety. I got a box of 10 for $33, effectively making them around $3.30 each. I went one step further and designed the furnace so that 2 of them could be made from one brick, cutting the cost in half, making each furnace a pro-rated $1.65 each!
They're extremely lightweight, and capable of withstanding the temperatures used in steel working, but soft enough you can cut and carve them with kitchen utensils if you need to.
In reading and studying history a bit, I learned that some of the earliest forms of light were made using carbon arc lighting. Large amounts of electricity were pumped through carbon rods, making a bright arc and providing light.
To scavenge carbon electrodes, I took a lesson from NurdRage ( / nurdrage ) a couple of years ago I saw his video on what could be scavenged from a carbon-zinc lantern battery (bit.ly/IBNurdRageBattery). It's useful to know what common everyday materials are made of, and these heavy duty batteries are containers packed with carbon rods, zinc metal, and manganese dioxide. I tucked the information in the back of my mind until now.
In this project I tried melting the zinc casings from the lantern batteries, and casting them into a small ingot, formed with a mini muffin tray. Be cautious of the zinc oxide fumes produced. I haven't personally suffered any ill effects from working with it, but some people claim it can give flu like symptoms, or a fever if inhaled in large quantities.
Zinc has a relatively low melting point 787.2°F (419.5°C), so the Arc Furnace is able to melt each casing into liquid zinc in around 5-10 seconds. That's amazing!
I don't have an exact purpose for the zinc yet, but it's an easy metal to work with, easy to cast, and great to have on hand for a future projects. It's also one of the main metals used for making a simple carbon-zinc battery.
The black stuff pulled out of the battery casings is manganese dioxide. It's a useful chemical for experiments with hydrogen peroxide, so it's worth hanging onto.
Although I haven't verified it, I believe any stick welder can be used to power the mini arc furnace, and for most hobbyists, that would definitely be the easier and safer way to go. I just don't own a welder, so I used the one I made instead. You can see how to make it here: goo.gl/H0FWxE
The longest I've run the unit continuously is around 3-4 minutes, and the electrodes get so hot at that point they can seriously burn your hands, or melt your gloves. I wouldn't recommend running it any longer than that.

You’ve been gone so long, yet many still find themselves returning to your videos because of your energy, and the methods you use. It improves peoples day and helps them be a better person. Thank you, you molded my childhood and my creativity which will be with me forever. You will never be forgotten. We all appreciate your time and videos. Thank you and may you rest in peace. Have fun in the paradise you so much deserve.
R.I.P relax in paradise. I tried this at home, did it 9 times with different metals each time. I had 2 muffin trays of different metals! Worked great for me!
Will it work on Tungsten???
Please let me know
@@shareeve7597 If it got hot enough to melt tungsten, it'd be 2-3 times as hot as these bricks are rated to handle, so I feel like that'd be super dangerous.

Haha! Probably. As far as cover-identities goes, it's a good one. He looks so harmless and good-natured, and then he shoes you how to make an arc furnace before he goes out to fight crime. I'm rooting for you, Grant!
Dan Brake It's Grant's fault! He led me astray!

This video brings back memories... Missing you bro😢❤
Love that his videos are still up an running, he inspired people to invent , discoverand to think outside the box . He will truly be missed. I still rewatch these videos for inspiration.

RIP man this was the first video I had watched of yours. Gives me nostalgia
I can see how/why the book came out. This style of teaching/showing science and the building is very interesting. While I don't think I will be making an electrical arc furnace anytime soon, it is very interesting to watch the process. I am very glad I decided to watch these videos from the beginning. It looks like I still have 5 years of content to go through. Onwards to the next video!!!
He was not a king. He was a legend, and legends never die...
Idk why but drilling the brick with the forstener was so satisfying

I built one of these when I was like 11 in circa 1962 and didn't heed the warning on using goggles. I ended up with a serious case of welder's flash, VERY PAINFUL!!! I melted anything I could get my hands on. I also laid the carbon rods on the cement basement floor and got a red hot spot on the floor. My brother told me how dangerous this was, the floor could have exploded in my face due to the expansion in the heated spot with no where to expand to other than to buckle and explode. Be careful......
did the welder's flash go away?
Yes, I remember at least one painful sleepless night.
wolfgang schmittenhammer, that was a very interesting and well told sotry there, you're not the only one who did dangerous stuff as a kid, luckly I never got injured
+wolfgang schmittenhammer deutsch?🤔
Half and half. Fraternal half Alsatian, maternal half Hungarian. Real name, Muckensturm, which literally translated is "flystorm"???? Mucke = fly , Sturm = storm. The arc furnace came from a book, 700 Science Experiments for Everyone. My other Bible was The Scientific American book of projects for The Amateur Scientist. Both books are still on my bookshelf. I am very lucky to have all ten my eyesight and my life. Have experimented with some of the most dangerous stuff on earth. X-rays, explosives, very high voltages and currents etc. At age 50 I got seriously burned. Was very heavy into serious pyrotechnics (fireworks) Mainly rockets, but also shellbuilding and large aerial salutes. I have also gotten rear ended and thrown from my motorcycle and 30 days after that got t-boned in my van by a Chevy Blazer running a red light at +35 mph. I still tinker a lot, it is what makes me tick.

Sir you just did this IN YOUR HOUSE

I JUST MADE THIS!!!! I used my welder for the positive and negative leads. It was perfect. I could melt iron like nothing. Thanks for sharing this years ago.
Can you melt quartz? :)
What amp is it
Purple Space Cow Studios and I’ll make a video on it too
Double tap airsoft I don’t know... I know it’s around 400 volts for my welder but not sure amps
Mine keeps catching fire, the output coils. Do you know input amperage or a better way to cool it?
You can also source carbon electrodes at most welding supply shops, they're used for carbon arc touches like you made and carbon arc gouging, the latter being the most common use for them today.
Amazing content, I had watched this vid years ago, but watching it again just blows my mind how succinctly he made videos.
This one is really cool, I remember rewatching this everyday during high school
Next week how to make a nuke with a cat and a rubber band
Next week he will cure cancer with toothpaste and dried out pasta.
Next week he'll be making a small space station for snails with only a can of baked beans
Next week how to cure ebola with wendex and pepper
And then after that he will make a fully functional Xbox using legos and a calculater

"According to the safety sheet, the dust is something you wouldn't want to get in your lungs."
Knowing me, I'd probably trip, fall onto the table right onto a pile of dust, get it in my eyes and inhale half an ounce of it.
lol
+Michael Griffin wut
Wear a mask that seals an protects your entire face then.
The mask would get caught somewhere and fall off then me with allergies I'd inhale most of it then sneeze and inhale more.
Working with this material you can reduce dust if you put the brick into water for a few hours before cutting or drilling or else.
This furnace can melt any metal known to men
Me : so youre telling me i can melt *nEtHeRiTe*
If you are talking something anything close to actual say gemstones, yes, yes you can
Yes
Ya don't get it, do you?
It is hotter then lava
It won't be able to handle a cactus
Really enjoyed this and it turned out to be what I was looking for, for a project in which I was going to rely on a propane torch that would supply too little heat. Thanks!!

I was about to say r/woosh
But ok
Be careful which batteries you choose, alkaline batteries will not work because (as far as I know) they do not have inner carbon rods, and also have highly corrosive alkaline material inside. You will make a mess and potentially get caustic gunk everywhere. What you want are Zinc Carbon batteries, usually labeled as "heavy duty". Double check the battery casing and make sure it doesn't say "Alkaline" anywhere on it.

Nathaniel Epps very truth
Ive got a Rayovac 6V General Purpose battery. No where does it say Alkaline. The only info is "mercury-free formula". Will this battery be usable?
usually people only watch videos like once but I watched this video like 12 times

You should explain why this is even happening and presenting some more alternatives to the batteries you've used. And how long do the two electric parts last? Do we need to replace them after a while?
