For anyone wondering about the difference between Wootz and Damascus steel they can be the same thing but Damascus is also used to refer to pattern-welded steel which is where two or more different steels are welded in layers to create patterns in the metal which can resemble the pattern found in wootz steel. Basically, Wootz exclusively refers to steel made in a crucible whereas Damascus can refer to either crucible or pattern-welded steel.
Both are same. Woozt the magnificent steel was imported from bharat to Damascus to make weapons. So westers tribes and kingdoms know it by name Damascus. Woozt is sanskrit name
the differences between welded steel like that and actual Damascus steel have been extremely well documented. That LOOKS like Damascus steel. It's as much Damascus steel as pyrite is gold.
Wootz is the historical Damascus of legend. Damascus refers to an aesthetic of patterns within steel made to mimic the aesthetic of Wootz (it's the difference between antique bronze and antiqued bronze). Remember that "Etched Damascus" is a term alongside "pattern-weld damascus" where "pattern-weld" is often just replaced with the style of pattern weld (example: butterfly damascus). And etched damascus is just regular steel etched with a laser or acid. If someone only calls it "Damascus" without being specific, they're selling you a gimmick. Demand specifics. You can have up to 5 different steels in one of those, make sure it's not 50% angle iron.
@@Cretaal Was all Wootz steel also historical Damascus steel then? So, If back in the day, someone took a good Wootz steel ingot and made a crappy blade, would that technically also be historical "Damascus steel"? What if someone took a Wootz ingot to England, would a blade made from it also be called Damascus steel? Could you get historical Damascus steel without the Damascus pattern? Or was that pattern something that was intrinsic to forging Wootz steel? EDIT: I had to add the term "historical" so there was no pattern weld/damascus confusion.

One of the best series I follow on UA-cam hands down! Such an interesting topic, with so many opportunities to explore various cool topics! Can't wait to see what the future holds for this channel!
Hello How to Make Everything team, you guys should check out high phosphorus iron. It's somewhat of a stop gap between wrought iron and steel. It's a lot more finiky to work with but would be an interesting topic to cover. There's even an old Norse saga that involves a magical blacksmith using bird droppings to intentionally up the phosphorous content of his sword. If you are looking to pursue case hardening father Clickspring has a great video on timings and mixtures to use.
Yeah, clickspring is a great channel. He introduced me to the idea of case hardening. Before that, everybody used to tell me that making any edged implement that way was impossible and a waste of time. Well, what do you know, it works like a charm :D
@@htme so, if I'm understanding it right, you basically have a brick bucket, filled with charcoal and "iron" (of any purity), the charcoal and the iron do not directly mix, so while both will get hot their different properties mean that they won't melt into one homogenous blob. If the intake is at the bottom, as the iron* melts and drips to the bottom it will absorb more carbon from the surrounding CO2 formed from the charcoal's combustion within the high-oxygen environment. If the intake is at the top however, as the iron* melts and drips to the bottom it is left in a low-oxygen environment where some of the carbon within it actually seeps out? (I assume mixing with the limited oxygen there is to form more CO2?
@@robonator2945 The carbon isn't seeping out but rather chemically removed through oxidation, the simple explanation is that oxygen binds incredibly strongly to other atoms so the carbon would rather bond to the oxygen than the iron. Once the iron melts it is however fairly unlikely to bond to carbon again until the fire is very hot, and of course you just make sure to stop the fire before the iron has time to absorb much carbon. In the other case where they're adding carbon they're keeping the iron in an oxygen poor environment, since the oxygen is reacting too quickly with the other metal and so there's only carbon there. The bottom of the furnace should also be hotter so that means the iron will end up absorbing carbon.
If you take that steel, and put it into a crucible, you can melt it completely into a solid ingot to Forge easier. That is how I was taught to make steel, before hammering it into nails. Nails were the first thing, from what I was told, every black Smith started out actually forging. That is because you can always heat them up and fold them into a larger piece later if you need something else instead of nails.
I've been told that nails are the first thing to master because they are good practice. They test several core skills, precision movements, and repeatability. All while not requiring much resources per nail, and, as you mentioned, they're still a usable size that can be welded back together with relative ease.
@@kassiog.6595 No, it hasn't been. I hate it when people think this and act so arrogantly in the comments like they have all the information when they know nothing, or maybe watched 5 minutes of a scochow video on Damascus steal that got it WRONG. There is a difference between pattern welding to make steel with the same type of design and pattern of Damascus steal (the well known Damascus steel traits) and actual, true, Damascus steal that was historically made from wootz steel (which also hasn't been recreated, it came out of the ground in a certain place and manufactured in a particular way that we haven't replicated. Most wootz steal was not good steal, and was mainly made into Damascus. Only a fewer ACTUAL Damascus steel swords still exist in the world. While the process was, again briefly recreated in the 1700's fairly successfully, it was again lost and now only a few REAL Damascus swords exist in the world now, and are in museums. Please do proper research before making these types of comments. Otherwise, you're just spreading misinformation.
@@kassiog.6595 I never said it was mythical all? It was a good steel that made a good sword that stayed sharp for a long period of time. In honesty, we probably have better sword steels today. That doesn't mean that we've successfully reproduced, true Damascus still in the effing 21st century. Someone please do some actual research, maybe read the full wiki ffs.
The first time i got interested in this stuff is when i was in welding school. I was assigned to make a power point about the hardness of steel. I never fully understood it until a couple years ago, eventhough that was like 5 years ago. Its very interesting, and i plan to make my own iron too, out of magnetite that ive gathered.
This is random, but I was binge watching HTME last night before bed, and I had a dream you did a colab with Adam Savage. I could die happy if this actually happened
One of the important steps in the development of battleships was the ability to accurately control the depth of hardening, allowing for the production of armor that had a hard surface but was backed by a more ductile layer that could flex and both absorb the force of an impact as well as stretch in response to temperature changes.
Nicely explained. Metal fabrication is my lifes work. You explain well the influence carbon has in c/s. (carbon steel). It has taken me a long time since I have been to the iron mines the colonists used in Orange County NY ( just north of the New Jersey line) in (1961) to understanding the elements making up different grades of c/s. I have a much better comprehension of the materials used in metal fabrication. Thank you tons for your efforts to make this story understandable.
"Case-hardening" is also called "cementing" and, in late-19th Century steel naval armor, "Harveyizing", after the US steelmaker who developed it using French nickel-steel armor as its basic material. The layer of high-carbon material is rather thin, though in armor it was usually about 1-1.5" thick, making up only the thin surface layer in thick naval armor used in cruisers and battleships of the period. The later thick-faced Krupp Cemented armor steel for naval armor used a chromium-nickel alloy for better hardening and tempering (toughening) but usually kept the thin Harveyized surface layer to make that layer extremely hard during the final hardening processes (a few types skipper the Cementing process and used the somewhat softer, but much tougher, thick face layer by itself for improved resistance to enemy gun projectiles).
Imagine the number of steps necessary into the adaptation of metallurgy between iron hammering by blacksmiths and Bessemer Method; then imagine whether there were more than two magnitudes (multiply by one-hundred) of steps necessary into the adaptation from sticks and stones to bronze. It's amazing.
As the technology progresses, the number of things to work on grows exponentially! I can understand why he’s put that off, but you’re right that it would speed things up quite a bit.
HEY! Good work on the metallurgy. I had to learn this shit in material sci - and it took me like three weeks to get my brain wrapped around the structure changes.
Just for reference the iron-steel-cast iron rough placements are a good rule of thumb. Bot nescessarily hard and fast rules. Super high carbon, high alloy steels can have well over 3% carbon in the mix. Rex 121 and zdp 189 are good examples. You can also have steels with very little carbon that instead rely on elements like nitrogen or boron for hardening. Vanax is a good example.
This process is really complicated to understand. I can imagine, that with nowadays tools it is really simple to turn carbon into steel and find the perfect melting point with the amount of carbon and heat, but I have absolutely no idea how he turned this out with his self-build oven.
Steel is still complicated enough that it's the single most recycled material, about a third of all steel produced is actually just recycled scrap steel. Steel Mills are also some of the largest and most expensive to operate factories in the world and require very skilled labor.
I'm halfway through this video, and all I can focus on is the fact that they are running a primitive refinery hearth...in the middle of a backyard FULL of long, dead, dry grass... 🔥🔥🔥
Is it possible that you try a video where you attempt to make coil springs using a primative method? I know they're a few hundred years old but I'm genuinely curious what the minimal amount of tools and methods you would need to produce them while still being functional.
Before the industrial revolution one of the uses for baleen was leaf springs for carriages. Coil springs, even earlier ones, have higher weight capacity, travel, and longevity, but there are organic workarounds to many of the applications we use metal for.
Thinking out loud with not much OJT in this chemistry area. Considering the relation to oxygen or lack of. Would the low carbon steel get more carbon in a surface treatment if your clay and char wrapper was discarded while Hot under or immersed in a Hydrocarbon or oil for a temper also? I am working on color case hardening or at least a DIY case hardening historically easy with tech of the day.
One problem with case hardening is when one wears through the hardened case to expose the softer core is exposed making a softer edge. It is likely that after sharpening enough times where the hardened case layer noticeably ran through, that the chisels may have been periodically returned to the smith to be re-hardened.
In some episodes of the reset they reference a graphic that looks like a family tree listing each technology. Is there a link to the full chart somewhere? Maybe at the end?
I saw a way to easily soften iron is to heat it up as much as you can. Then bury it in leftover ashes to cool over night. This will soften it and make it very workable.
The genral idea, despite mathematics not playing into physics for a chunk if history, was an engineer tested a bunch of stuff and established connections between things, like how sooty a fire was and how brittle the iron became

the reason i think that the wrought iron was crumbly is because of all the little holes the bloom has in it, you should be refining the bloom at welding temp
Might want to try making other wood working tools like a wooden hand plane, im wondering how one would make a flat square plane body without already having a hand plane.
You'd make a large enough blade that it can plane an entire piece of wood. ;P Just kidding; it'd have been done by hand with plumb lines (more accurate than a level) and probably sanded down using a large flat stone to get a mostly smooth surface.
@@snowpaw360 Yup, planes are incredibly old tech. Also, just looked into those ancient planes more, and seems that instead of relying on hand carving a wooden mount they used a thick, flat iron sole under wood or ivory grips! I guess flattening metal against an anvil would have been much more easier to get that flat than what they could get with hand tools to surface a plane, plus it'd be far more durable.
@@snowpaw360 Yeah, because of the ivory handle; the rest of the plane was the same as the one recovered at Pompeii and others recovered at other sites, however.

We love Adri in this household!
Great vid
Late to the party, but I gotta say that "It's Never Sunny in Barovia" tee is great! Oh, also the amazing metal working too 👍
Is it possible that you try a video where you attempt to make coil springs using a primative method? I know they're a few hundred years old but I'm genuinely curious what the minimal amount of tools and methods you would need to produce them while still being functional.
Before the industrial revolution one of the uses for baleen was leaf springs for carriages. Coil springs, even earlier ones, have higher weight capacity, travel, and longevity, but there are organic workarounds to many of the applications we use metal for.
Thinking out loud with not much OJT in this chemistry area. Considering the relation to oxygen or lack of.
Would the low carbon steel get more carbon in a surface treatment if your clay and char wrapper was discarded while Hot under or immersed in a Hydrocarbon or oil for a temper also?
I am working on color case hardening or at least a DIY case hardening historically easy with tech of the day.
Man, the edit on this piece was all over the place.
really cool episode! I didn't know that steel casting is such a complet process
The name of this episode should be "Solving the Riddle of Steel"
Discussing the topic of iron and steel, could you visit/comment on the Iron Furnace in Southern Illinois, not far from Golconda, IL?
16:25 - I love the [Car Park] sign LUL.
Nice Steele anvil. Great blacksmithing channel
I learn so much from your channel and I love it thank you
My fav vid yet man. Keep it up.
Is the percent of carbon by volume or by weight? How do you determine how much carbon is in a steel?
4:01 it's never sunny in barovia -T-shirt LOL
now I have to look up Barovia
amazing video as always! Love everything you do! Keep it up man!
You put this on the wrong end of the playlist lad. It’s at the beginning, rather than the end of the playlist
Question, how did you get all of those ting pieces consolidated into two bars of steel and iron?
Can you buy steel wire and heat treat it to get different grades of hardness?
One problem with case hardening is when one wears through the hardened case to expose the softer core is exposed making a softer edge. It is likely that after sharpening enough times where the hardened case layer noticeably ran through, that the chisels may have been periodically returned to the smith to be re-hardened.
4:00 That dude's got my hat!
Can we get a full adri episode? I love their work and presentation so much!
lol we know why you think that. their work is actually quite shit
Yessss. I was admiring the nail polish the whole time
That's a nice Alec steel anvil 😁
In some episodes of the reset they reference a graphic that looks like a family tree listing each technology. Is there a link to the full chart somewhere? Maybe at the end?
Doesn't case hardening wear away with use and sharpening?
It's been a long time but I knew I recognized the name barovia. Awesome shirt!
Is it by weight or by volume that the percentage is measured
I like the sound of that anvil. What is that 140 pound Steele brand? Nice.
I saw a way to easily soften iron is to heat it up as much as you can. Then bury it in leftover ashes to cool over night. This will soften it and make it very workable.
I didn't get a notification for this even though the bell is on? I didn't know that was possible
The genral idea, despite mathematics not playing into physics for a chunk if history, was an engineer tested a bunch of stuff and established connections between things, like how sooty a fire was and how brittle the iron became
Worked in a steel foundry for 3 years I can help with ur core making and venting. Plus ur pour pressures. Example ur iron swords ur neck was to small as was the pour cup in the mold. I made everything from crane plane train parts to oil wells excavator teeth and even a Francis impeller. But alot alot of farm equipment and chemical plant flanges.
Love the schnauzer in the background helping
outstanding vid as always
4:54 I see, a Curse Of Strahd fan. (Low key, got really happen when I saw his shirt)
Impressive hand work.
How is the small furnace called? I can't remember.
hey what about a belt sander or just sandpaper that woulld be a lot better than a rock or a grind stone?
Did you consult with clickspring about case hardening.
u managed to make some nice square steel there in the end!
You want to talk about the relation to carbon ion and steel.
Why don't we talk about the understanding of yeast to everyday life?. From beer to bread. All around the world.
For the nixtamalization of corn to make masa.
Incredible
Does some sort of hidraulic press would help more than just hammering the material? General noob question here
I only watch these videos in the hope that Adri shows up
The Riddle of Steel! Crom is proud and you may pass into Valhalla now.
I think this channel will rising again, good luck
Excellent video! I learned alot
Thus looks like it'll be a great video!
The riddle of steel!!!
Love the videos as usual. Have you thought about having some different background music by any chance? The music you've used for years isn't bad at all but maybe trying something new may freshen things up a bit. Doing some more collabs with other creators would help bring a new audience.
Also, a good strategy on Patreon would be to raise the entry donation level (instead of 1-3-5, maybe 5-10-15?). Patreon only shows the first 3 donation levels to people, then you have to click "see all" in order to donate more. People's eyes naturally focus on the option in the middle and may not even see the option to donate more money. Just throwing out ideas and it's all meant to be constructive critism. Congratulations on your success, been watching for roughly 5 years. You've come a long way.
I loved this video. Great stuff
the reason i think that the wrought iron was crumbly is because of all the little holes the bloom has in it, you should be refining the bloom at welding temp
Forgive me for missing it, but how did putting the cast iron back into the furnace remove the carbon?
look at the position of the air intake. how high or low it is
Might want to try making other wood working tools like a wooden hand plane, im wondering how one would make a flat square plane body without already having a hand plane.
You'd make a large enough blade that it can plane an entire piece of wood. ;P Just kidding; it'd have been done by hand with plumb lines (more accurate than a level) and probably sanded down using a large flat stone to get a mostly smooth surface.
@@KainYusanagi Just looked into it, oldest plane we have found was in pompeii, so they are a very old technology
@@snowpaw360 Yup, planes are incredibly old tech. Also, just looked into those ancient planes more, and seems that instead of relying on hand carving a wooden mount they used a thick, flat iron sole under wood or ivory grips! I guess flattening metal against an anvil would have been much more easier to get that flat than what they could get with hand tools to surface a plane, plus it'd be far more durable.
@@KainYusanagi Well they theorized that one your talking about was owned by a rich artisan.
@@snowpaw360 Yeah, because of the ivory handle; the rest of the plane was the same as the one recovered at Pompeii and others recovered at other sites, however.
"its never sunny in barovia" i love that guy's shirt.
So there WILL be a crucible steel video? Exciting.
