@nightHawkinLight not sure if you are anywhere near new england, i frequently run across access to strange materials and components from my job (recycling technology, a lot of weird edge case tech flows through). if you are in my region i might be able to help source materials for projects.
I'm a knife-maker and when you first showed us your version of starlight, a forge liner was my first thought, but I never got around to testing it. Glad it will work.
@@BSpinoza210 I have not had time myself, unfortunately. In process of moving workshops now, but I imagine the main issue would be outer layers flaking off. Still, it should work well enough and would be cheap and easy to replace
i thought about using it for selective hardening, and maybe a plate for stuff to cool on. i got a background in chemistry and am working on a batch right now, i modified it a little by adding magnesiumphosphates. quite excited how it will turn out.
@@littleh4xx0r let me know how it goes! I use a product called NuClay for differential hardening. Works great and dries quick. It's also water based, so it cleans up well afterwards, too!
5 minute crafts is full of BS, half of the stuff they do makes no sense at all. If i had to say this channel reminds me more of what King Of random was when Grant (RIP) Was doing the projects.
The King of Random has a really good, cheap build, but you should invest in a good crucible. I've been using mine for over 3 years. It needs a little repair (this video inspired me to try this putty for patching), but works really well.
riuphane do you mind sharing where you bought it from? I also want to melt some metal but I don’t have a good crucible, and don’t know much about what brands/sellers are good.
@@ChristianAverage I got a MorganMMS Salamander Super Crucible and it has treated me very well. I don't remember where I bought it from, somewhere online for about $50 and it's pretty big, especially for hobby work
Metal buckets seem to work best. Good and thick metal, sturdy, small enough to still have a handle, easy to drill into, etc. All of my new furnaces are of the metal bucket type and all different sizes. The paint cans also seem to degrade quickly compared to the metal buckets. Most large metal buckets are fairly cheap as well.
One trick to extending the foam life would be to coat it with low sodium milk of magnesia. It will dry and fire to a magnesia coating. Magnesia made in this way will have a melting point in excess of 2500C. Adding a little borax will lower the melting point but make the coating more durable in handling. You can apply several layers and build up a very durable coating.
That's an interesting idea. Might try it out if I ever make one of these. I wonder if there could be a counteracting effect where the higher melting point of the magnesia ends up inhibiting the intumescence of the starlite. Definitely would be interesting to see it tested :)
Oh heck yeah. This is super handy information to know, super useful, super cheap (like omfg how is it possible it only takes like $15-$20 and like 20 minutes to make this stuff?!) Thank you an absolute ton for sharing things like this with all of us. I've already written down the recipe for this homemade 'Starlite' recipe into my mad scientists notebook as well, and again thank you!
Ben, I just want to take a sec to thank you for all for time, hard work , awesome content and overall just being a cool guy. Thanks for the Education and entertaining content love your channel man and might I say I love you as well!!! Keep on trucking man thanks again!!
Used this to build a forge and used it as a furnace too: I was able to melt silver in this thing! This is amazing, paired it with some cuttlefish casting and literally anyone can get going
U mean u didn’t use a crucible and used the forage as lining ??? Wasn’t liquid silver stuck on to it … how much did u put in before melting and how much weight did u get back ??
Nighthawk you're brilliant and the smartest youtuber I have ever watched, I love how you are so humble that you answer our questions and comments, and not only educate us on how to make something but also to explain every little detail of the science behind it, I truly love you.
As a long time blacksmith who started making gas forges in the early 1980's and who made a large variety of things, I look for sturdiness in a forge liner. If I can't maneuver odd shaped pieces in and out of the forge without damaging the forge badly, it is useless for a lot of the work I've done. That said, it would be useful for forges used for a lot of knife making and work that is easily put in and taken out of the forge. I will make a forge for small work and see how it works for me. Great idea! I rally like your experiments.
@@drkastenbrot it might not be as durable or as long lasting, but it would work as a cheap, temporary fix until the proper insulator can be found and installed in the case of a repair. But then again, it's not really something that a company would try to patent because anyone can easily make it and nobody would actually buy it if they can easily make it. Also, the question wasn't would they, but rather who would win.
@@torjones1701 That's a lame take that doesn't really withstand critical examination. It's intellectually dishonest to suggest that Boeing's scientists couldn't have figured this out when your only evidence is that they are not using it. The logical conclusion from what we know would be "the material does not have properties that would make it useful for Boeing's business."
I've been thinking about trying out blacksmithing and for starters I'm worried to overspend if the experience doesn't turn out positive and i end up moving on, this would certainly help keep cost down and ever since you published the very first starlite video I've thought of this specific application for it. I really am grateful for your work on this matter. Hopefully this will be one of many projects around this material, cheers!
In my DevilForge, I can have molten aluminum in 12-15 minutes from cold.I have a few videos on my channel of it melting and the speeds it will melt. I will have to try your design out for some smaller projects. It looks like a super easy and cheap design!
Thank you, thank you so much. I was just getting into knife making and was trying to see how to get a forge for cheap when I got the notification for this video.
This is a good start, and i also have an old video about making a soup can forge that you might be interested in. That one used a plaster and sand lining which works well.
What a good channel, I mean, really. I was thinking about making one of them forges a tad while ago after looking at the starlite video, now nobody's gonna convince me otherwise, thank you for the tutorial, good fella
This would be great for protecting areas nearby a repair in way of cutting torch (blue wrench, LOL) or welding. Also, an easy ablative replacement for harpoons or similar rocket launching at the backup structure where flame impingement occurs.
I'll definitely build that. I've wanted to build a forge for a long time but I don't have access to refractory materials or even plaster of paris for the DIY refractory. I do have access to baking ingredients and borax so I'll be building this awesome forge in the very near future.
Far away from any type of material shop. I don't have a car and due to Corona, the bus is reserved to people who actually need it to go to work. Which is not my case.
@@bastienguilbaud5768 oh, that's a shame, hopefully we can get a better quality of life for everyone who needs it soon. I dont know about you, but I'm sure ready. In the meantime, for materials you can't obtain perhaps you could get a friend or family member to mail/ fed-ex you what you need. Best of luck.
I actually made a much smaller furnace a while ago when you released your first video on the subject. The forge worked using a wax fire, and got hot enough to melt small amounts on aluminum foil that I left inside it. It was only a test forge though, and was very small. The insulation worked amazingly though, I could even pick it up while it was on!
I'm not sure, it might work for a few trips at least. I don't know that a camping stove really needs a fireproof lining though. A normal steel can usually does fine.
You could take the ingredients with you camping and just mix it and apply to the can when you get to your location. That seems like it would be the easiest way to do it and make sure that it doesn't fall out in route.
I guess it would work great as the insulation of a portable rocket stove, not receiving as much direct heat and beign lighter than other materials I've seen used. Plus you only need small twigs and they go a long way
@@rwbimbie5854 Yes. The fear was that it was part of a 'plot' to take over the country, as it was when there were efforts to put fluoride in drinking water. Nowadays, the bull***t is that if you get put in the hospital because of Covid 19, you'll die, the real cause of death being that you were intubated, not for any other reason.
Why is this getting so little views?? This is one of the coolest and most useful pieces of content on youtube and it only has 65k views??!! On a channel of 1.6 MILLION! This is one of youtube's fatal flaws; not promoting great content when "the algorithm" doesn't deem it so.
Thanks for making this video! I'll be doing a side-by-side comparison soon where I test a homemade intumescent-coated forge against my Hell's Forge single-burner forge, so when that happens, I'll update this comment. Keep on rocking! :)
Sir, you are truly a GOD send. I have needed the information on almost all of the videos you have shown for my huge project of making a derigible. I will definitely share my ideas and videos with you when I start the project.
Thanks for sharing this! I’m likely going to use this technology to line a rocket stove made from soup cans to keep the internal temperatures up. Some rocket stoves see temps above 2000C at the core! The higher temps allow for complete combustion of the wood fuel
BREAKING NEWS: Man makes an indestructible compound using grocery items Edit: No, but really, you're one of kind! Just continue this endless journey, can't wait to see where you get!
This video is SO practical, now I’m finally gonna have a forge! SoI’m binge-watching Nighthawkinlight videos since re-discovering them after the algorithm took them out of my feed. This is the third today, and once again is supremely useful. I’ve wanted a forge for occasional use for a long time, but the hassle of firebricks or commercial refractory mix, finding & modifying a big steel container, etc, etc kept me from making one. This is so dead-simple that I could whip one out tomorrow. It’s finally something I’ll actually do. Super-kudos and thanks (again) to Nighthawkinlight!
You might want to use a plaster/sand lining instead of the starlight. I found this doesn't last long. Tkor has a good video about making a good forge lining from plaster
Hey if anyone cares, I’m coming up with a cheap concept to pursue knifemaking with that combines my specialties by building an induction heater with starlite on the inside of the copper coils and a MAPP gas flame inside. Haven’t seen a hybrid like that before and I’ve been trying to use starlite for this purpose for a few months now
Ha! Here's an idea- Bundle the ingredients and a bar of stainless inside a coffee can Package includes a hammer, tongs, a 5" flat slab, and a torch Market as "custom pocket knife, some assembly required"
Theoretically it should work fine, as long as you have a sufficiently powerful heat source that doesn't need oxygen. Should even be more durable in the absence of oxygen (as long as you don't have some other oxidizer).
@@Lucius_Chiaraviglio I think so too. I was just wondering if this process gives the material some special attributes. It will definitely not smoke or smell after the process.
That's essentially what he already did. The reason this stuff lasts is because it's burning in a relatively low oxygen environment. It would burn extremely fast in an environment with 50-100% oxygen
i just made my home furnace with portland cement as a lining with fire brick. it is cool when melting but super hot to touch afterwards. I might try this one as a lining to reduce heat transfer to the metal casing. hopefully works as intended. thank you for your video! 🎉
You showed in your previous video how to make tiles . I would suggest you put these tiles on the outside of the can ,a paint can will work as well as a coffee can plus the advantage of the can being one that holds paint you can use the lid coat it with your material to reduce the heat escaping out of the top. Thanks again for the video
Great I think I'll try it, it's been several months that I'd like to try to melt aluminum and cast it in sand. Do you know how many runs/hours does the 'starlite coating' last in usual conditions ? Thank you a lot !
It will probably last several hours (I would guess 4ish hrs) of constant run time, but I think repeated heating and cooling cycles will shorten its lifespan.
Agreed, making content internationally friendly is very considerate and helpful. 1000 grams did sound a little strange to me though, hopefully in future he'll take advantage of the power of the prefix.
@@colinyoung3685 I noticed that as well but it is justifiable - kitchen scales show grams and the following ingredients were all less than a kilogram. Also it hardly matters because SI prefixes are aligned with our base 10 number system, so conversions are easy.
I know, when i first saw it, I thought good i already have one of those, but sadly not the same. I'm sure glad he told me what I needed now, Instead of my failure and inevitable trial and error.
This is a fantastic idea for my use case of metal melting. All linings degrade over time, and low cost is important to me at this point at the expense of somewhat lower durability
And of course any Borax left over can be used in the forge welding process. The putty you describe has the advantages that many (don't personally know if all) refractory fibrous materials used in forges are dangerous if breathed in, so for a quick and dirty quick forge, as you say it should be good to go.
I was thinking of putting this putty in a rocket stove and in a forge too. But last time when you said it will eventually burn through, I didn't want to put it to work and build a permanent forge instead. But the idea of making a smaller forge like this, which could be used a couple of times for small jobs is as simple as it gets. This is a really fantastic, simple and cost-effective solution for small jobs... . Right now I have a clay jar with charcoal and a small hand-cranked toy fan for small jobs. I think this will be way cheaper, easier and time-saving. Here is another thing I thought. Since its pliable and moldable, why not make silicon molds . It will help replace the inner lining faster and we can stock the starlite molds ready for use
I have tested this using your recipe. I am very impressed, this actually worked! i could not feel any heat on my skin. This honestly works wonders. Thanks so much. I wonder if this can be mixed with sand to make more of a durable refractory. Will have to try it out with this.
This is amazing, I’ve wanted to try metalworking but didn’t want to put a lot of money into it so even if this isnt permanent solution it’s still a great one, especially since I don’t have to go buy firebricks or anything fancy
Wow, this video went up the day after I started looking for forges and how to make them for my new workshop that I’m building, thanks! Now I can use this until I get a proper forge
