Gotta admit, I had a goofy smile on my face during the pouring of the ore and reveal of the sword. It was very easy to get pulled into their infectious enthusiasm. Excellent job!
To be pedantic, that's no ore, that's an alloy! Copper Ore looks nothing like that at first, and also going from ore to a bar of tin is quite a process, when you combine the two refined metals, then you'll get that!
Neil is a great artist......... Amazing how effective and good bronze weapons really were.. And some of them were way above any sword since in beauty...
noone as far as i know makes and sells better, and also more accessible swords than neil, he is THE one man to approach for any european or near eastern bronze weapon or tool.
I think he thought that the molten bronze looked kinda like blood, then said "better than blood" as to say it looks cool, glowing all red hot and what not.
Two queries this raises for me: 1. How long does the molten bronze sit in the mould before it gets dunked in the water, and then how long after that does it sit before being extracted? 2. Considering there's a fair amount of waste, what with the spilled bronze while they're pouring it into the mould, the amount that's stuck to the pot, and the bits around the edges of the sword that'll have to be chipped off to finish the weapon, can any of that be reused for another piece?
I made one here at home by myself. Turned out good. I cast mine sideways. instead of vertical. It was sand cast instead of clay . Once I took the grinding and polishing, it was a dandy sword.
Did you build a wooden pattern and flask? I can't figure out how they used their pattern in this video because they don't show it. Looks like they're just using clay with no flask, but they don't show how the pattern was applied and removed.🧐
Celery God Oh, that's what you meant. Well, it still is a sword made for either historical researching or collecting purposes, so it would be perfectly fine
It was kind of a joke based around the fact that the U.K. is inventing new terms like knife violence since they banned everything except knives. People who originally were just gonna shoot someone (a cleaner less painful kill) now are forced to stab or slice them to death (a rough, bloody, painful kill). Now ask yourself, some dude's in your house about to kill you with something, would you rather it be a gun or a knife?
Celery God In what awful fucking neighborhood do you live that people just come into your house to murder you? Have you tried locking your door? And if I had the choice, I'd choose neither, ideally. Doesn't really matter
Hi, yeah if you want to hit things with the sword then it would need to be heat treated otherwise it would bend and lose its edge. Heat treatment profile for 440C is to heat it to 1000-1050°C, quench in oil to harden it, then temper at 100-300°C for a certain amount of time (can't remember off the top of my head). This strikes a balance between hardness (holds an edge) and toughness (doesn't break like glass). It also keeps a nice corrosion resistant finish so it won't rust (normally).
The mold is made of grog ( aka firesand and chamotte) It's a ceramic raw material. It's formed over a wax model of the sword and baked at 400 celcius to harden en burn out the wax model. ( lost wax or cire perdue technique).
availability, technology, time, and the fact that it wasn't weaker. Good, work hardened bronze can be often harder than mild steel or iron. Iron was around for hundreds of years before anyone thought it could be useful, because its so bloody difficult to work. Bronze is much more simple to make, and is a lot better than people give it credit. I've enough research and experience to cast a bronze sword, but despite also researching steel forging, i know my first attempts would be shit. The first thing I made in bronze was an axe, and its still to this day in good nick, it's a good deal better than my mild steel hatchet. Also they barely oxidize, its been a year, I haven't polished it once, and its still shiny.
No culture ever used cast iron for blades. Cast iron is brittle. If I smacked you with a thin cast iron bar in the shape of a sword, it would crack, or possibly straight up break.
You could cast iron to get the initial billet to rough shape, then forge it after the fact as per normal; in fact this was done centuries ago to create what was known as crucible steel. Even if you didn't go all the way to steel, due to the process being deficient in some way, forming that initial billet to rough form and forging it afterwards means that it's no worse off than a cut-and-fold-then-hammered billet.
Or to prevent people from acquiring possessions that belong to you. But let's not drag nuance into the conversation, this is the RUclips comments section and we can't have that.
xXHacksAndTipsXx No one in the last 3000 years has used a bronze sword... But in the bronze age it was the ONLY sword... And you know early bronze age swords wouldn't have been hardened because they hadn't figured it out yet... This particular episode was about the bronze age, and this part was about the very beginning...
Are you sure that's not just a rumour? I can't say for sure, but it sounds like what you're referring to is the steel used being harder, and thus holding a sharper edge for longer, but at the expense of being more brittle. The higher carbon content of softer steel makes it more malleable, so it absorbs more impact and doesn't break, but also blunts easier. Various smithing techniques mix up the various hardnesses in supporting structures and the like.
thanks you for that information. it's always been sort of a rule of thumb for me. i have had bad experiences in the past with steel cast swords and knives. once, the tang broke on one of said knives while doing a cutting test and the blade made a 2 inch incision in my right forearm.
I'm going to guess the water was from when they doused the mold (hence why it was hot,) and they really used a hammer to break apart the clay. Clay fired at extremely high temperatures is more heat resistant than most metals (bronze for sure) but much more brittle, making impacts very good for separating it from the more malleable and impact resistant bronze.
Thank you. If you're looking for information on weapon forging sadly there aren't any documentaries with enough depth to be interesting that I know of. I mean, even this video only shows a fraction of the work required to forge a bronze sword. Plus many documentaries are full of mistakes and sometimes even lies, especially those on the katana... Good luck in your quest.
As for a blade that is much stronger, you can't beat the limit of steel. Things that matter in the steel are the size of the grains, which you want as small as possible, the cristalline structure, the carbon contents and the overall distribution of these. Grain size is reset on each heating before quenching, and once quenched the blade mostly keeps the metallic structure. A revenue (tempering) can be added, but if you do it for too long you will weaken the blade. Hope that helped.
they still have to shape it a bit more the have to get rid of the excess metal on the sides and give it a good polishing and it will look absolutely beautiful
The series doesn't have much more about weapon making, it's more about history in general. Sadly the series got deleted from youtube before I watched the last episode. But apparently they visited an old copper mine and so on.
That depends on many factors. Grains only form when the metal solidifies, and increase in size from that point (mostly, austenitisation is enough in steel to reform new grains). If you cool it slowly, you can still avoid having large grains. Also, a heat treatement can fix them problem. Bronze would require a heat treatment to form precipitates.
Think about what ur saying, Forged sword are bound and compressed make them much harder, forging also allows for continuous cooling and re heating to make them much harder, molding only alows it once and the sword is much weaker, because of not being beaten by the forger, being beaten reinforces the sword and in turn makes a lot more durable
Layers are mostly used to even out impurities, and for aesthetics value. An eutectic steel will already be filled by "layers" called pearlite, and those are natural. Layers in a martensitic steel don't change anything though. This is why folding was used in europe too, but later abandonned, because they were able to produce better quality steel to start with.
Are you kidding??!! If old craftsmanship such as traditional smithing dissapeared, you can't get it back. The level of tradition, craftsmanship, art and experience that goes into these ancient crafts is priceless. Thats why it's so important that we as a race preserve these crafts. Japan held onto their traditions during the meiji restoration. If they hadnt there would be no popularity of samurai, ninja etc. Many traditions would have been lost. Youre obviously very young and have much to learn.
As for folding, it was done to even out the carbon and impurities. The impurities are broken into smaller ones that won't weaken the blade as much. More advanced smelting techniques meant that folding became unnecessary in many cultures. Plus, inclusions of oxydes and coal are added at each folding. Folding too many times, it becomes useless because the layers are thinner than atoms. The number of layers are the powers of 2, which means folding about 10 times was the most commong thing to do.
Now does the carbon in casting come from the cast itself? I heard the carbon makes it brittle but it also helps high carbon metals retain a deadly sharp edge, sort of a trade off. That's why the whole folding process in certian eastern swords made them so special. Using high and low carbon metals to craft a blade that wasn't too brittle and still sharpend to a menacingly deadly edge.
Thank you for the rather quick answer! Is there a bit welsh accent in there? Because i have watched Trochwood (which plays in Cardiff, Wales) and I think I can hear some similarities.
The actual use of a highland sword (longsword) was to splinter shields as the standard shield was made of wood or leather. The romans soon found that there standard practice of hiding behind their shields and jabbing at their opponent from behind the shields did not work. One strike with the highland sword cleaved it in two, that left the romans with no defense and a very short sword. Curved swords did not seem to originate in japan but instead with other eastern nations.
Could be, well my opinion about the sharpness of the swords made by folding is because basically they are consisted of many thin layers, and even if you hit a wall with that sword, because of those layers it will stay sharp, not sure how to explain why is that using words :)
Well I've seen many people commenting here that didn't even know the difference between steel and bronze. The heat treatement can be applied to cast steel too. Cast steel can be reheated as well as reworked for more precision. Oh and tempering was used for steel too, which produced even better blade. Basically you cool it down a bit too fast, then reheat it at lower temperatures. But again, these have nothing to do with the shaping method.
I'm not a native English speaker. But could someone tell me what 'to cast' refers to in the phrase 'To cast a sword'? Am I right that it refers to the throwing of liquid in the mold?
They didn't do it that way at all. They would build a furnace, half buried, with a higher and lower hole. They would melt the bronze in it (usually from the ore). The higher hole would lead to a large "pit". When the bronze was melted they would open it to get rid of the floating slag. Then they would open the lower hole, that would lead directly into a mould. The Bronze would directly pour into that mould, without any slag since it was already gone the other way.
i know this is extremely late but bronze actually does the opposite of steel when quenched. Instead it becomes softer. however, the edges can be hammered in the process of work hardening which makes the bronze much stronger again.
Gotta admit, I had a goofy smile on my face during the pouring of the ore and reveal of the sword. It was very easy to get pulled into their infectious enthusiasm. Excellent job!

Better than blood says the Scotsman
"it's like blood... better than blood!"
???
he's a vampire, mortals like us would never understand, leave it be please.
"better than blood"
what
I think he thought that the molten bronze looked kinda like blood, then said "better than blood" as to say it looks cool, glowing all red hot and what not.
When you accidentally reveal your lust for blood #justvampirethings
yeah wtf, nothing is better than blood
Two queries this raises for me:
1. How long does the molten bronze sit in the mould before it gets dunked in the water, and then how long after that does it sit before being extracted?
2. Considering there's a fair amount of waste, what with the spilled bronze while they're pouring it into the mould, the amount that's stuck to the pot, and the bits around the edges of the sword that'll have to be chipped off to finish the weapon, can any of that be reused for another piece?
that's just incredible... the beauty and results of the process are breathtaking!
one question, Is that sword lightweight?
It's not only 1 guy
I made one here at home by myself. Turned out good. I cast mine sideways. instead of vertical. It was sand cast instead of clay . Once I took the grinding and polishing, it was a dandy sword.
Did you build a wooden pattern and flask? I can't figure out how they used their pattern in this video because they don't show it. Looks like they're just using clay with no flask, but they don't show how the pattern was applied and removed.🧐

Casting creates weaker weapons as compared to forging
yeah but what's the point of using a weaker weapon in a battle?

people wouldn't use steel and iron, if bronze was better.
No culture ever used cast iron for blades. Cast iron is brittle. If I smacked you with a thin cast iron bar in the shape of a sword, it would crack, or possibly straight up break.
Now bronze swords were cast, yes. But they implied iron was also cast.

The BBC does it right.
How did they finish it and polish it? I know modern forges use grinders and what not but how dod they make such beutiful sword back then?

It's metal, but probably a mixture of metal elements which have a higher melting point than bronze, so the container itself doesn't melt :)

But again, these have nothing to do with the shaping method.
What are the pots made of where they put the melted bronze in?
Now that, ladies and gentlemen, is hardcore.
Neil Burridge: Pretty goddamn metal.
I'm not a native English speaker. But could someone tell me what 'to cast' refers to in the phrase 'To cast a sword'? Am I right that it refers to the throwing of liquid in the mold?
The only honest reporting BBC ever did was about sword....never would expect this, but I'll take it.
Why is this video linked to every other video i visit?
They didn't do it that way at all. They would build a furnace, half buried, with a higher and lower hole. They would melt the bronze in it (usually from the ore). The higher hole would lead to a large "pit". When the bronze was melted they would open it to get rid of the floating slag. Then they would open the lower hole, that would lead directly into a mould. The Bronze would directly pour into that mould, without any slag since it was already gone the other way.
The drop in temperature could weaken it, but I suspect they just edited out the part where they actually hammer it or so before pulling it appart.
What is the material of the "container" where metal is melted?
Can bronze be hardened or tempered like steel, by quenching?
i know this is extremely late but bronze actually does the opposite of steel when quenched. Instead it becomes softer. however, the edges can be hammered in the process of work hardening which makes the bronze much stronger again.
So fire!
What was the pot (the one that held the liquid bronze before it went into the mold) made of?
