Tip! I built my own version of this exact burner & forge a few days ago. Afterwards when it dried I noticed the lining was getting soft & powdery after firing. I could scratch it off with my finger nail. So I created a hot saturated solution of LYE. I kept it on the stove on low heat (steaming, not boiling). Then used a plastic syringe to drop / coat / saturate the entire inner and outside lining with hot lye solution. It took about 2 hours to do and soaked in nice and deep. It needs to be hot otherwise it doesn't penetrate nice and deep. After I finished I decided to take a mini propane torch and heat a soft section of the lining that was breaking off before. Then when it cooled I touched it and it felt like a ROCK. Was hard as hell. So then I set off the forge with the wet lye all over the lining and THIS WORKS BEAUTIFULLY. First you'll see the steam come out (do not breath it in). Afterwards you can actually see the lye melt and immediately react with the silica in the perlite to make solid water glass. The whole lining changes aesthetically & structurally. You get hundreds of small, white popcorn looking beeds all over the lining but their all the same size and it looks awesome. After I fired it for 15 minutes I came back with a screw driver poking parts of the lining that were soft before and it was all ROCK HARD. I couldn't scratch off or break anything. But here's the coolest part, the forge is getting WAY HOTTER now. Before only the bottom got yellow hot... after I did this the entire liner gets white hot and bright like the sun. My guess is when you seal the liner like this heat is reflected like a mirror ... there's no pores in the liner for heat to dissipate or penetrate through. So the second heat hits the liner its reflected immediately back into the forge which makes it get insanely hot. I'm not exaggerating one bit. Afterwards I stuck a stainless steel spoon in there, held it a few minutes with pliers, pulled it out and the entire top of the spoon was gone! Then I shut the forge off, looked inside and see the steel melted to the bottom of the liner. So naturally I had to connect my MAPP gas. I tried it again and the entire base of the spoon melted too. So I shut the forge off then popped it off with a steel wire and it came out like a little pancake. I have no idea how this thing is melting steel (I'll take pics if anyone wants to see) but I need to try larger amounts in a graphite crucible to see if I can melt and pour larger amounts. I'm also confused as hell about the difference between temperature vs heat energy? I've been reading on forums about this. Anyone knows you can put a thin steel wire in front of a 1000C small propane torch and that steel wire will melt. So when a forge is properly insulated and your pumping hundreds of thousands of BTUs in it.... what's happening? Is it because the metal is more thermally conductive than the silica? So when you're pumping heat into an insulated area... the heat keeps rising and rising then you throw steel in... that steel sinks the "heat energy" which causes the temp to rise then it melts? That's the only thing I can assume is happening. And if I can melt a steel spoon that has to mean I can melt more steel in a crucible.

Your forge could actually be used in glassblowing to reheat the glass as you continue to create a vase etc. You are very intelligent& resourceful. I enjoyed your video!

Thank you for being alive and for taking the time to share your gifts with us.

This was the most exciting thing I have ever seen in my 32 years of age, or 17,289,672 minutes or 1,037,380,327 seconds old. Keep me updated when you make coffee out of a forge.

I love this video. your voice/attitude is like david wong from the movie john dies at the end. and you are accidentally doing asmr and no your not boring just relaxing.

woahh that camera zoom was amazing

Followed your sodium silicate vid and now this one which i made out of a new gallon paint can and fired it up......This is going to be a blessing over my brake drum forge. Thanks for the great details

Really nice burner nozzle you designed! I'll be making one of these soon and appreciate the build!

From a woman's point of view, I think you do a great job and don't let other people get to you. They wish they could do what you think to do!! Enjoy yourself and keep the videos coming! I know my husband and I really enjoy them. Good for you!

Mind blow!!!!! I love it, i have perlite, i have a coffee can baby powder yes! I have THAT too! :-) i'm well on my way to making my very own forge! Thank you for sharing, i'm excited just thinking about it, boo yaa subscribed and liked

I just did this with a paint can and it worked out well. I can't wait to learn more and keeping practicing.

Wow...that is awesome...this is the best forge I have seen by far on KZfaq. ....really quite impressive...and done with items you might and most likely have lying around at home

What are you doing today? Oh, you know. Just frosting my forge.

6:54 that's one hell of a camera.

Good job! You look like you know what you're doing. I look forward to more. Explaining some of the reasons for doing your build would help. Keep up the good work!

Awesome video for your build! Love the way you did the project! Thanks for sharing!!!

I've always wondered how plumbusses were made.

Christ! If that hacksaw slipped... !

WOW! This is well thought out. I saw your video on making sodium silicate. You are so helpful by sharing your sources of all the products used. thanks.

Very interesting and informative. When the forge I just made gets worn out, I'll have to make one like this. Never thought of using perlite

that gives me an idea of how to take an UNinsulated safe and INSULATE IT!!!! I figure if your fire wont get out, then a house fire wont get in. THANKS!!

Where did you get the valve for the disposable propane bottle or did you make that one? if you made it can you tell me the components I need to make one. Thank you

Great tutorial with few amount of words and no annoying music. Keep that up.

Dude, that was freaking awesome. Thanks for the tutorial, I’m looking forward to making myself one. Keep up the good works!

Pretty soon all these mom and pop stores with special crafts will be obsolete. KZfaq is gonna help everyone do it yourself. I seen a news article about a mother and 4 children building an entire house with 8 bedrooms and brick exterior by using KZfaq how to videos. 😆😆

how much would you sell one of these for if i wanted to buy one from you rather than make it myself?

The use of Perlite and liquid glass is pure genius.

How can you not like this? It's freaking cool!

please build more and sell them on EBay.

I have no idea why Im watching this video...

Thanks for the breakdown of burner building. Very nice.

Excellent do-it-yourself video. You are very resourceful in your construction - outstanding!

Does it need to be Folgers, or can I use the cheaper Butternut can?

If anyone is having a hard time finding the Apple Corer. These are virtual identical as far as the stainless tube is concerned. Norpro Apple Corer - Model #: 5103 - www.amazon.com/dp/B004L04PV0/ Fox Run Apple Corer - Model #: 5547 - www.amazon.com/dp/B001BHHN0G/

you are a genius ... it make so easy ,inexpensive and can be done after morning coffeee before noon !! Thank you so much for sharing the idea ...i'll start it right away by getting components today .

AWESOME VIDEO! This is definitely my next project for my shop! I make custom knives and this is way handier than having to fire up my large forge to forge smaller bush craft knives.

+RTOHIO It was part of a 3/8 fitting I sliced off for another project, then filed the flats off of it. A 3/8 to 1/2 face bushing also works. I did not know there were that many people wanting to build this exact burner haha, Designing your own is fun and rewarding. Thanks for the comment!

i made one of these but it melted, maybe i should have used a metal can instead of plastic.

Thanks this idea is going to save me a lot of money, I saw the soupcan one but yours is bigger and will be of more use to me. Thanks again for upload xx

Thank you. Great process and workmanship. Bravo

Melt down some lead and dump it down a big ant hill, wait a min😏 Then dig it up 😐 Looks like a lead piece of coral ☺ PS. If it's a really big ant hill Prepare to dig, and a good bit is needed for it to look good

Cade Howell, sorry your comment dose not have a "reply" botton, so I can't reply to it directly, my plan is to use it for heat treating.

The apple corer as a burner is pure genius!

That was very informative. Nice work!

I was really hoping the directions would be: 1. Cut coffee can. 2. light on fire. 3. stare at fiery death machine.

hmmmm 911 dislikes..... COFFEE CAN FORGES CAN'T MELT STEEL BEAMS!!!!!

great video, thank you for adding "all" needed information !!

this is the first vid i have seen of yours. i love you already! you rock!! thank you for share sir!!!!!!!

Do you guys know what the full ramifications of heating this stuff up and breathing the fumes, I am sure there is a good scientific reason why the industrial community is NOT making these on a regular basis. Sure would be nice to have one of these on my worksites across america.

my only question is...who drinks Pepsi Max?

Does anybody see a problem in using this method of making a forge , but using a much larger container like a “35 gallon “ propane tank from a forklift (about 30” long, and about 15” in diameter), and make it with a 4” cavity. Out of all the mixes I have watched on Ytube....... this seems to be by far the easiest to deal with and get the best results. Thank you for sharing.

Nice job. You've produced a simple cheap forge that anyone can make. Good vid too and very well explained, thank you.

cement could used just as easy.. and cheaper..

how did i get here? from porn???

Thank you, I have all the parts now! I'm going to build the trash can version with my boys. I also picked up a decent size kiln which I hope to make into a foundry. Thanks for the inspiration and instructions!

I have absolutley no reason to have one of these yet I still watched it all....good stuff.

Thanks for making this video, it helped firm up my understanding of gas burners. I'll have to try making an arrayed burner for a large propane forge.

This is an incredibly well made video! You sir, are a boss!

As far as I know, you're the first on KZfaq to use these chemicals. If this works for an extended period, you will be a hero of sorts, because the system has us all believing that "refractory" material is 4th in the Trinity; as in importance and price. This is an exceptionally good video.

Very cool ! Great idea !

That 1st zoom was badass

Top build, freaking awesome.

that burner is sweet

Great job! Well thought out. I enjoyed watching.

Thank you! I don't know what I would do with one, but I enjoy this sort of thing a lot! Nerds of the World Unite!

nice job mate, very inventive.

Really nice video, very easy to understand too, thank you!

Try setting you burner at a 40 degree angle. Heat will circulate inside a bit better, and can raise the temps some. Thanks for the videos, I found one that will allow me to finish an on going project.

very very nice.simple to do and seem to be efficient !

Thanks for the advice and taking the time to read my tex.its just a dream off mine to make this oven iv been toying with the idea for about 3 or 4 years now I hope that one day I will get around to doing this as I do love experimenting plus I do love pizza too lol all the best and have a great day

Awesome project! Thank you for sharing. Sure beats paying out over a hundred dollars to a few hundred for a factory made one! We all gotta keep remembering that we CAN do amazing things for a low price like this... to never forget the old presidential saying, "do what you can with what you got!"

Thank you great video Exactly what I have been looking for.

sweet build!

Wow this is so cool, thanks for posting!

Great job and great vid. It's good to see the DIY revolution is running full steam everywhere.

Nice recipe. Thanks for sharing.

This is pretty neat

nice video made almost the same thing about 10 years ago lots of fun !!!!!

Metal recyclers also have materials they sell by the pound. If a coffee can is worrisome you can find heavier bits at the recyclers. If you live near the coast where ships are built you can find exactly what you want often in stainless. Loiusiana near the oil rigs should provide any size you can imagine.

This sounds Dangerous, But my curiosity wont let me stop watching!

Great video!,Thanks for sharing!

Thanks for sharing your knowledge.

I thought this video was amazing. Even if it might take some cautious experimentation to use the notion for hobby purposes, thank you for the ideas. :)

My friend you have just made yourself a rocket engine.

Great job mate :)

I used perlite and furnace clay from the hardware store. Worked great for years.

I liked watching how you made the burner, the new tube design of what seems to be a large scale of a soldering torch tube. I'm soon going to make one and make a foundry like yours in this video but a bit larger so I can melt larger pieces of metal just to compact the size. I will use free fuels to burn them, either reclaimed fossil fuels, used motor oils and old fuels mixed using them to extract vapors that will burn not using them as solid fuels if I can make my design work it will make the fuels last so much longer and will be free.

that was so cool and I will try to do the same thing with an old oxygen gas bottle.

That's So Awesome Dude. Keep up the great work. Nick.

this is very cool im definitely making one of these

Great work!

Good man , a real maker :)

...Like the way u working... Awesome vids, thanks alot

Very cool great job.

awesome, very good idea

Awesome stuff man

Very cool, clever man.

Nice work

Very nice video instruction.

Great idea!
