Now I am going to tell you more how I made a stainless steel knife using a thermite reaction. - วิทยาศาสตร์และเทคโนโลยี

Yes, yes, yes! Im blacksmith and was trying to find a way for a long time to make my own alloy, but the forge cant reach the temperature to melt chromium or nickel. Now the problem is solved! Thank you soo much!
Why does my forks and spoons and other cutlery rusts if I give them a quick soak even though it says stainless steel stamped on the underside of them? They are cheap, a dollar for 4 of them. I usually don't get these kind of cutlery, but I needed some after moving to a few states away from my home state and just left everything behind that I wouldn't be needing them and have more space for more important things. Either I would let relatives have the stuff I couldn't carry or not needed or donated stuff. So when I went to Walmart I was debating on getting plastic picnic ware or just go ahead and get the cheapest metal ones. The cheapest metal ones were the 4 pack for a dollar so I picked up two of the forks, 1 of the table 1 of the teaspoons. Brought them home cut the tape that was wrapped around them, stopped up or plugged up my kitchen sink and dropped them in some hot soapy water. The first soak and wash went well not rust but when I soaked again some rusted some didn't and I'm trying to figure out why they did when it says on the underside stainless steel?
Why did some rust when I only soaked them about 5 mins. The 1st soak was longer about 30 mins to an hour. I used hot water the hottest water that could come out of the tap.
You think it would of been that soak that done that but it was the 2nd 5min soak that done it in hot water but not as hot as the first one. So why did they rust? Sorry for it being long I was trying to making thorough as possible to understand it better.
Thank you and have a wonderful and blessed day and stay safe!

@@starchild7843 I am also a blacksmith, and I've actually made quite a bit of kitchenware from stainless steel. Despite its name, stainless steel can be rusted. The corrosion (rusting/tarnishing) resisting property of stainless steel is Chromium, and most stainless steel contains a fair amount of it, in some cases up to 14% Chromium. Though even with 14% Chromium, the iron is still susceptible to rusting, especially if left in a solution (soaking) for a long time.
Unfortunately, I can't say for sure why your cutlery rusts, but I have a few ideas. The most likely is that the steel is simply just not of good quality. A stainless steel with a much lower Chromium content will still resist corrosion, but it will begin to rust fairly quickly if exposed to water over a long period of time. Alternatively, the water you're using could have something in it that induces rusting. I'm not too sure, but perhaps if your water is slightly too basic/acidic, it could erode past the surface layer Chromium.
Hope this helped :)
There is a different more traditional way. That would be putting all the metals/elements in a crucible together with glass, sand and/or a kind of flux that doesn't produce gasses cealing it up and making a kind of furnus that can reach those temperatures. Like the one from the documentary secrets of the viking sword, where they try to recreate the ulfberht sword. Coal can burn up to 2000 C which should just be enough to melt chromium but a thermite reaction does burn hotter. The thing is that it takes some time to heat up and for everything to mix properly. They used to feed air into the furnus with bellows but now you can run an electric pump. Just make sure it displaces a large enough volume of air and can run for a long enough time. I've been wanting to do this myself but I don't have the space so I've been trying to find a place that will allow me to do this.
Also a lot of stainless steels actually have a slightly lower melting point than regular steel. when you have molten the iron the chromium and other higher melting temperature elements will slowly dissolve in it which will change the melting point too.
@@starchild7843 On a boat out at the salty ocean stainless steel rust within a month... If you want something that do not rust at all you need Acid Resistant Steel.
@@starchild7843 stainless steel is very rust resistant but all of that goes out the window if it gets exposed to even microscopic rust particles from let's say a steel wool Brillo pad that was just used. If left on the surface all those tiny particles become nucleation points for rust to form and eat away the surface finish. Cleaning it with some sort of abrasive will remove the rust but the longer it continues to sit on the surface the deeper the pitting will be.
Amazing to see something go from the raw ground to a finished knife, because it's done by non-automated, small manual steps. Great video!
I look your video in Russian language, and now I start looking your content in English language because I want Learn English. Thanks for your content 🙂
You make knives out of lasagne? That's crazy!😄
Looks so tasty... AH! MY FACE IS ON FIRE!
@@erstwhilegrubstake 😆
This was absolutely fascinating. I never thought about using the thermite redox to get the components in the alloy at the same time, so damn cool.
Glad to see the refractory layer in the pot and addition of flux helped you! It’s a simple addition but makes a big difference.
Ive noticed in some thermite reactions with chromium, the slag can be fluorescent red under UV from the creation of synthetic ruby, but I don’t know if you had any appear in your stainless steel slag.
If you do end up doing any chromium heavy alloys I’d recommend a bit of oxidizer to helps things along like NaNO3 / KNO3 or NaClO4 / KClO4
Great work on the video and excited for the next one!
adding oxidizer sounds like a great way to make that little pot really blow up haha, definitely take precautions and scale up slowly with that mixture
@@TheRealSykx you've never seen any of his videos, have you? Check them out. @The Gayest Person On TH-cam is the go to person to learn about thermites and how to mix, react and get different metals from. He has a whole series on making different metals from thermite reactions. It's extremely interesting and awesome to watch.
@@BackYardScience2000 I am patiently waiting for the next upload.⌛
@@TheRealSykx absolutely! Always take safety seriously when working with molten metal. The amounts of oxidizer I’m talking about adding starts as low as 3-5% and works up from there
Thank you for some tips in you thermite video series, waiting for them to be continued.
Now that was unexpected and very interesting, I follow a lot of blacksmiths and love the craft. I've also watched them smelt iron ore in homemade clay furnaces in the field to make cast iron, then hammer and fold it to get out the impurities. This is a whole new path, much easier IMO. I'd love to see some Blacksmiths try this process, and see the end results. Nicely done, and very educational. Thanks!
Great idea.
Please share this video with those blacksmith channels. I'd bet with enough of the viewers of those channels seeing this method, it might encourage a few of them to give this a try.
That's really neat! Didn't know you could use a thermite reaction to produce steel.
oh ya that's one of the products of the thermite reaction: Fe2O3 + 2Al => Al2O3 + 2Fe
when reacting it tends to fling molten iron around, so it's best to keep a safe distance
A good one.
@@TheRealSykx If you watch the video, he shows how to make it not fling molten iron around. if you watch the video, that is.
Now you know.
Also a method for fusing train rails together. There are multiple videos on that process, it is pretty neat!
WOW!!! I didn't think you could make stainless using thermite! AMAZING!!
Your a bad ass science guy. Great video. I love to learn about metals !
You should make more of such videos with and actual end product, they will definitely be popular.
Thank you for showing the failure as well as the success! Excellent show!
Well Done!
Excellent video as usual. I had no idea that a thermite reaction could be used to make alloys. I have made soft iron ingots using a kilo of thermite, but stainless steel is totally next level. A note for anyone trying this at home: Iron(III)oxide powder can cause serious eye damage and potentially irreversible damage to the digestive tract. Also the fumes can cause heavy-metal fever. Stay upwind!
The magnetite powder on the magnet looks so cool, haha. But this is really interesting! I didn't know you could do it this way.
@0:10 - Frankly, my friend, I REALLY want that periodic table. It's just awesome. Beautiful.
I can’t believe how good your videos have become - the music was exceptional! Great visuals, narration and science content!
Good on you! Amazing video! Showing your first attempt, tells me how honest of a creator you are. This should spark a movement within the custom high end blacksmith/blade making community. As an artist, I love the idea of having my own precisely formulated material to work with.
There seems to be alot of Estonian TH-camr's considering the small size and population of Estonia, and most seem to be Intellectual based content(history, science, military doctrine, ect.) Maybe it's just TH-camr's algorithm suggesting more Estonian channels. Either way keep it up Estonia, the more Estonians that become popular in around the world the more the people from other nations will support Estonia and force their governments to take action if Russia decides to go full Soviet Union.
That's the problem with Ukraine, nobody in the west knew where, what or anybody from Ukraine so we basically stopped paying attention 2 weeks after the invasion.
do you have some recommendations for Estonium YT channels?
slava ukraini. #ihaventforgotten
This is surprisingly a more approachable version of how tamahagane has been made for hundreds of years, which the surprising part is more people don't use it. If you ever decide to do it again, I'd add a few pinches of Nickel in place or in addition to the Chromium, a dash of Manganese, and a pinch of Vanadium, then set it off with KMnO4 and a few drops of glycerin/glycerol. Then when you go to the forging process, folding the blade will remove impurities and close up the grain structure (reducing inclusions). The big inclusion on your blade will Definitely become a point of failure during heat treating.
It's a bit more time consuming getting the amount right as you have to factor in shrinkage and forge losses, but if done correctly, you can cast thermite directly into a graphite mold like a billet or a larger version of your final product (ala sand casting with a graphite powdered barrier to prevent the steel sticking to the sand), then go to town on an anvil. I like to use the billet method as I'm going to fold it anyway for better grain structure.
the problem with thermite is that its not 100% iron usually its a combination of iron oxide and aluminum oxide beyond which can be added manganese etc but my point is shrinkage thermite shrinks quite a bit simply from the fact that all of the air gaps got burned out not to mention that the aluminum oxide would burn off to slag leaving you pretty pure iron getting steel out of the process is frankly fascinating
amazing that 2 powders can contain that much energy
now while your grinding skills need some work this is really impressive! not only did you make stainless steel but usable stainless steel! very nice to see people finding loopholes in science and chemistry like this!
Not loopholes, on the contraty he used chemistry at its finest
Very entertaining and educational. Start to finish projects are among my favorites. Thank you for sharing!
Excellent!
Thermite is so versatile, and you can do so much with the process. It is a wonder that it isn't shown to be one of the earliest ways to make iron and other alloys of iron. Bauxite and iron oxide works as good as aluminum powder to make thermite.
Bauxite already has oxygen attached. How is it going to steal oxygen from the iron and other oxides?
Aluminum requires large amounts of electricity to be extracted from bauxite.
@@HenriFaust No, it requires heat, which we use electricity to produce with carbon rods in the bauxite. The excess oxygen reacts with the carbon rods to produce MASSIVE amounts of carbon dioxide gas and liquid aluminum.

Well done! Thank you for teaching us!
Hardness test was performed without sufficient support, measured value of 200 Hardness Leeb D scale is indicating wrong measurement- annealed steel has ~500 HLD, thus any piece of steel You may find and measure will have at least 500 HLD. For example, hammer head should have at least 700 HLD. To achieve proper reading, support knife blade on a heavy( couple kg) flat steel piece, store-bought kitchen knife will have at least 700 HLD~= 50 HRC.
This interest me a lot you do make science fun!
I learn so much watching your videos. the knife turned out great. nice team effort
Totally terrific. Thank you
Your shirt is EXTREMELY cool. The content you're giving is very interesting. I have been following you for years now, and the content still feels very fresh and good! Continue the good work :)
Really enjoy your videos , please keep making all you can.
Great video, thanks for posting!
I've been absolutely enjoying your content, and this one is greatness. Chemistry is always something that's fascinated me. Blacksmithing and forging have been a fun hobby this past decade. Nice job on the knife. Don't trust that epoxy too much, more preferable to have a mechanically fixed handle to the blade versus trusting adhesive alone.
That is really impressive. Well done mate!!
the thumbnail looked like a pizza at first now I'm hungry haha
This is in my top 5 video of the years. just wow!
Crude, but mildly effective.
Stropping it will improve sharpness.
This was a very fascinating video!
Thanks for sharing
You deliver excellent content to your audience. All of your effort put into creating this video is much appreciated. I'm truly grateful for your help!
Fascinating!
Awesome blacksmith 🤘🏼 This was awesome Boss.
When in doubt use a flower pot lol
Natural progression of ancient technology. Fascinating. Exciting. Most interesting.
Fun with thermite. This reaction is also used to win uranium metal from yellowcake.
That was awesome!
Nice chops man!
Awesome cemetery experiment!
So awesome man. Really really awesome. Please keep up the great work. I am going to sign up for a Patreon account and support you.
Love the channel. One of my favorites!! You are so skilled and good at explaining. Every video is so interesting
Well done!
Soooo cool man!! I've always wondered about thermite's ability to make forge-less ingots
Great video and you've given me some ideas with my own experiments...
Really good content. Definitely one of the most interesting videos I have seen on youtube.
Fantastic Video!
Please do another video on thermite and it's ability to make tools. And testing the properties of different metals to make tools such as a chisel, hammer, axe or even tongs. All of which require different property's of steel. Such as hardness, flexibility, and workability.
low key amazing
This is very awesome!!!
Thank you for preserving the past!
Amazing the elements are so different given the subtle differences in the atomic composition of nucleus protons & neutrons & shells of electron orbitals, especially the valence or outermost shell playing such a pivotal role in electron exchange the makes enzymes & so many chemical reactions move towards products from reactants once the EA or energy of activation provided //
Love this channel
Well done. Love the shirt too 👍
I'm so glad I subscribed to this channel
Awesome 😊
AMAZING
well done sir.. awesome video..
Love the music
What an amazing video!
I like the method of using thermite to create an alloy. Very Cool
You sir are a boss!
I love your channel.
Full stop.
I love you so much! Love to Estonia from US
Super cool man!
Very awesome!
You are just awesome!!
Once again bravo
Me: Sees thumbnail
Also me: Instantly hungry for pizza.
perfect video!! I like it a lot!👌👍
this is what happens when you have a chemist and a blacksmith in your party.. hahaha
Dang, that was really cool.
Ooo, this was nice!
That nugget looked so good, I have to try this one day
Would it have helped to dissolve the iron from the rock powder and then reducing it with some base chemicals before doing the thermite reaction?
The best channel!!! ❤️😎👍
I am retired chemist. I have done job in Ferro alloys, nonferrous alloys, minerals, glass ceramics, coal lignite, soap detergent etc. By cast I am black smith. I like your video thanks. 🙏🌺❤️
The thermite technique is very impressive, and I think that's the reason why your knife will perform better that any other knives out there.
Awesome! I couldn't like this video enough!
Awsome video and love the LP shirt
great vid
Wow amazing and awesome
From the thumbnail, I'm just going to assume the knife begins its journey as a well-lit but slightly overdone pot pie.
I think he should have welded the inclusion before finishing the grinding process( which could have been polished out afterwards). but I am no expert, and he is DEFINITELY SKILLED! and you never cease to amaze me!!!💪🏼👊🏼💯
You're crazy! I like it!
Nice video, keep it up 💯
well done but the part you called tempering was actually the quench the part with the oven is tempering, sorry I'm a knife enthusiast and felt compelled to correct that
Impressive! But after all that what do you estimate your knife cost to make?
Awesome video! Loved it
love the "DIY grinder" lol
hi sir nice videos can u help anti iron formula ., and troch defuse formula
🙇♂️ yes ! Excellent video 😎👍
excellent result. you should have collaborated with alec steele for the forging.
Really cool video
