Making Coke Fuel for Melting Metals
In this video I show how to make coke fuel from coal. I use the coke to melt copper in my foundry.
Here is a link to the video of my first attempt at melting brass:

Making a Plaster and Sand Foundry
มุมมอง 11K7 ปีที่แล้ว
In this video, I try to melt copper using a foundry extension for my forge and coal as my fuel source. I used Grant Thompson's recipe for the insulating ring. Here is a link to the video of my first attempt at melting brass: th-cam.com/video/98CZmDTrg4A/w-d-xo.html
Melting and Casting in a Backyard Forge
มุมมอง 3K7 ปีที่แล้ว
In this video I show my homemade backyard forge. I use coal for fuel, which gets hot enough melt aluminum and blacksmith steel.
congrats, my history teacher loves you. -Nova high
The forge design is brilliant ill take inspiration from it thank you
Thank you so much for the video
Based.
So you used coal...to make (coke) to then melt copper.... clever. I've been trying to understand the coke process....this helped.
Thanks 😎
immersive engineering
Grind the coal into a powder and blow it in with compressed LNG.
hello, can you do this process using charcoal (not coal)?
I have worked in a steel mill coke plant for many years. You are making a mistake by crushing your coke. If anything, I would separate screening the coke from the coke fines which is called coke breeze. I would have used Coke Breeze on the bottom of the furnace and let the crucible sit on these fines to protect your furnace lining. Then I would use the coarse coke to pack around the crucible so when you put your blower into the furnace, you got good ventilation throughout the coke charge and even more heat. This is desirable like in blast furnaces using coke is to have screened coke without coke breeze which closes off the air to combust the coke. Coke Breeze is not desirable. Lump coke is what you are looking for and if it is not crumbly, it is best for the most heat and this is called coke stability. High coke stability means the coke won't crumble into the coke breeze. Coke breeze is detrimental to good iron smelting and lower temps because of reduced hot air flow through the burden (charge of coke). Coke produced for iron and copper are practically identical. Don't crush the coke next time and try to have coarse pieces from 2 cm and up for your size of furnace with little or best is no fines.
I was an engineer at a manufacturing company that produced hand poured aluminum and bronze castings. The brake rotor and tree branch poking stick must have been a process they did before I came in the morning 😂 just kidding, I love science and would probably do this experiment if I had time.
I don't know if you already know this but you can use steel wool to reinforce your plaster of Paris and play sand mold it works like rebar in concrete
Plaster makes a poor furnace lining because it has no strength and cracks easily. Without refractory available, I would use one part clean silica sand, one part Portland Cement, and one part vermiculite. Vermiculite can be bought in bags at a plant nursery. Mix all three ingredients with no water. After the mix is well mixed, add a little water to be able to make a wet ball that does not fall apart, either not too wet or dry, but can be cast or troweled. Again, this is not a true refractory but will be superior and resist heat much, much better than plaster which is only hydrated lime. Using Portland Cement and sand brings your mix to work well almost to 1600 deg C. Also, using screened coke without fines will also greatly get more heat to melt copper and even gray iron. Maybe use the Coke fines that is called Coke Breeze as a bed on the bottom of the furnace to keep the crucible from sticking to the bottom and protect the crucible from breaking.
Wow. It cleared so many concepts for me. Thank you so much
So much information in so little time, with very basic equipment.......... one of the very best educationals on TH-cam :) I checked your other Vids' I reckon it deserves a subscribe and a ticked Bell = done :)
Your crucible is chipping away because it has a metal mesh screen on the inside. To make good coke, build an actual coke oven using fire bricks. To melt copper, you do not need coke. Simply use a crucible with a lid on top with a 1-2” hole on top and keep dumping your charcoal or wood around the crucible and induce air “hot air preferably heat gun or hair dryer etc “ and you will have no problem melting soft metals like copper and aluminum. If you need to reach 4000 degrees so you can melt iron, brass, steel etc. than you’ll need coke and a crucible that’s inside an isolated forge. There’s various chemicals that can be added to the chamber to help expedite the heating process faster. Good luck.
Hey....can you please help me out
Can you please tell me which is harder ,coke or coal???
Very useful videos but the video's audio (sound) is really small, I maximize my laptop's speaker just to slightly enough to hear. At least your voice is quite clear so I can still keep up to what you said. :D

Charcoal is just cooked wood. Coke is just cooked coal? Lol makes sense
Coal is a mineral dug from the ground and was naturally created over millions of years. CHARcoal is wood that has been heated under vacuum and is man-made. Coal and charcoal are not the same material. In fact, some charcoal manufacturers add coal to their briquettes to increase their energy density because it burns hotter than pure charcoal. Lastly, if you were to put charcoal in a coke furnace, you wouldn't produce the numerous byproducts of coal, including coal tar, ammonia, light oils, and gas. The more you know! 🌈 🌟
Tbh I think you need to find a new hobby 😆
Perhaps, you can try some carbon anodes with low moisture content the next time. Buddy we can help ! 🙂 cheers
The most inefficient way I’ve ever seen someone melt copper !!! Ever
My guy you really gotta get you q propane tank to put your plaster mold in. Use it to line your propane tank. Put holes in it and make it a gas forge.
The best way to make your foundery is to use clay with steelwool mixed with it .
You don't seem to know what you are doing
The environmental contamination in this guys yard must be massive
Thank you for posting this. Probably saved me a lot of headaches.
Can somebody PLEASE tell me difference between COAL, CHARCOAL, COKE and METALLURGICAL COAL. Thank you
Coal is what is dug out o the ground. Coke is coal which has been roasted to leave almost pure carbon behind. Charcoal is wood which has been roasted to leave almost pure carbon behind. Metallurgical Coal also called Coking Coal is a type of coal well suited to the production of coke.
we put liquid paper on a bee
Your can went brittle as chips because carbon did diffusion into the steel, increasing the carbon content. To prevent that you can use a metal with a fusion point higher than the work temperature, and unable to solve carbon, for example coppper. Greetings from Argentina
How to control moisture in drag and push both type of oven during quenching of hot Coke?
how do you ignite coke? I tried and I just cannot ignite it. it doesn't burn at all.
Umm... you forgot to mention anything about the dangers of making coke. For instance one of the bi product gasses of coke making is benzene... you probably shouldn't be doing that
Coke made iron cheap and abundant. One of the greatest discoveries of modern era.
It's a sad state when I search how to make coke one TH-cam and get Coca cola or cocaine videos, smh it's very clear where our priorities are, cheers.
Your WhatsApp number?
Definitely coming back to this video in about 10 years when I have my own backyard and mini metal foundry with homemade charcoal.
So, youll need to insulate better. The lid should also be made of sand and plaster. The steel rotor will just wick away heat
Anthracite is basically natural coke. Very little impurities. Only thing is its not as porous
Cool video. Thanks for sharing
Innovative, smart, and resourceful! Looks good!
5:08 are you covering your forge with metal? but metal is going to leak heat which is a waste of time and heat. You need to isolate the heat.
The "smoke" coming off of that coal... is Coal Gas... a VERY flammable gas that has been used for centuries as a flammable fuel. Now you just have to figure a way to gather it, condense it, mix it with a flammable liquid it will dissolve into (like putting CO2 into water to carbonate it), and then you will have a liquid fuel that will burn VERY hot. :-) Also the tar can be used as... well... tar. You can patch a driveway with it if you make it into Asphalt. :-P
Tar can be used to isolate water from wood like in ships or home roof and so on, and it can be used as medicine to treat some skin and hair disease for cattle's and humans but I don't recommended using it without caution because I read that some people are allergic? and too much of it can hurt the skin? IDK Anyway, if you extract tar correctly you should get 3 tar thickness, light tar and medium dense/thick tar and very dense/thick tar and each one has it's own uses. Also I think (I'm not sure) that tar is going to have different properties depends on the type of the tree/wood.
If he had made a biochar stove and used coal instead of wood in the retort he would have have a very efficient system.
The of gassing has some burn ales btw…was used for a while for light before natural gas
In the year 0. They could have used a leaf blower, a crucible, pliers, steel bucket...Thanks for showing us what it takes to smelt copper in 2021 and not year 0.
Your dedication to efficiency earns a sub from me, sir. Kudos!
Gonna have a kid just so I can wait for show and tell and give him a bag of coke to bring.
Here before this vid blow up
What the hell is this???
I came here from that "Coke being pushed out" video.
How to make coke]... FBI on my computer: !
