            It depends on what they were doing with it. Jewelry, yeah I’d be pissed. Mixing with tin or arsenic, oh you better believe I’d be pissed unless the steel didn’t melt. Beating it into tools, nah we’re good, and I want more of this weird silver copper.

            Actually I think the biggest issue here is that it’s wildly unlikely a Sumerian metalsmith is able to actually do anything with steel. Their forges aren’t likely getting hot enough to really do much with iron, and steel is way harder and less malleable than bronze. Maybe they can sharpen it, and depending on the shape they might be able to cold work it. It looks like iron forging was a few centuries away in Ea Nasir’s time, and it required better tools, techniques, and forges.

              Yeah, but you can cast bronze fairly easily, while casting iron is more of an AD technology. Early modern, if you’re European. Traditionally you don’t even let it melt while smelting.

              Blacksmithing with wrought iron is way harder than working with something like bronze. There’s slag in it either just from oxidising or from the solid smelting (bloomery) process, and so it has a kind of “grain” that builds up over time. If you don’t account for that your sword or plough will be trash.

              It also rusts, is softer than bronze (even as most steels) and not necessarily stronger. The only real advantage is that it’s common and doesn’t require a trade network for rare elements, which is why it didn’t fully catch on in the Near Eastern world until after the bronze age collapse.

                Even if it is something you drink, the futuristic beverage may be something that’s more like a liquid all day amphetamine. A culture coming from coffee or tea where a cups are consumed mostly in the morning, but possibly at several points throughout the day may find themselves struggling with the idea that they’re supposed to take a small sip whenever their focus wanes or to take it early in the day and not sip on a beverage over the course of the day.

                This is akin to handing Ada Lovelace a raspberry pi and maybe the electric equipment to turn it on without frying it. Theoretically she might be able to do something with it, and she may very well be the best person of her time to do something with it. But without input devices and other electronics like lights or monitors or any other output devices, what you’ve given is a world of possibility without the capacity to do anything with it.

          Seeing as they didn’t have steel tools at the time, I doubt they’d be able to work it. I guess they could resell it as just a really hard sheet to someone, but it probably couldn’t easily be made into anything else.

      Vastly.

      It’s in the same column of the periodic table as silver and gold, and while less rare than the other two, still isn’t exactly common. Bronze, like a bronze medal, is just copper with a little bit of something added for strength. On the other hand, iron is one of the typical things rocks are made of. (Edit: Oh look somebody already linked Wikipedia)

      I’m surprised you haven’t heard of copper theft. Cutting wires out of things is kind of an infamous way to pay for your next fix of drugs. The power lines near me all have signs warning that they’re just copper-coated.

          Per the other commenter, it’s about 10x what steel costs. That’s closer than I was expecting, TBH. Maybe that it comes in easily-cut wire form is a big part of what makes it desirable for thieves.

          Margin is a funny way to put it, though, since there aren’t really any fixed expenses. Like a lot of criminal goods, supply is restricted more by risk of getting arrested than anything else.

      Iron is stupidly abundant. That’s awesome because steel is super fucking useful for boring hard duties like construction and tool making and basically all steel is majority iron by mass. It’s also reasonably safe and easy to extract in a moderately pure form with modern techniques unlike other super abundant elements like silicon. There are special steel formulations that can be wildly expensive, but there’s a handful that are dirt cheap because they’re easy to make and widely useful.

      Copper isn’t like, rare, but it’s no iron. It’s also often mixed up with other stuff that makes copper mines ecological and health nightmares (at least here in the us). It’s also become rapidly more and more in demand as the world is shifting towards replacing fossil fuels with electricity, causing higher demand for more and more copper for wiring and motors.

      For real though iron is just crazy abundant

        Good reply, but one nitpick:

        It’s also reasonably safe and easy to extract in a moderately pure form with modern techniques unlike other super abundant elements like silicon.

        Silicon smelting is arguably easier. If you have excess quartzite in your furnace it won’t form silicon carbide, while steelmaking involves being really careful to not get too much or too little carbon in the melt. Silicon becomes expensive for electronics because the industry wants 99.9999% purity absolute minimum. What comes out of the arc furnace isn’t read except for use in other metallurgy.

        I’d also like to point out other elements can do the same basic all-around-skookum-alloy job as iron, like nickel or titanium. It’s just that none of them are everywhere.

          That’s fair. At the end of the day, however you cut it, we live on a planet made primarily of iron, and though it’s most concentrated in the core, it’s still very abundant and at a very high abundance * usefulness * ease of processing to usefulness value

            Yup.

            I should probably mention silicon is a terrible metal for anything structural, as well, so that was never an option. It’s below carbon on the periodic table and brittle like it.

              Does silicon even form metallic bonds? Silicate minerals however are structurally useful as are carbonate minerals, they just can’t do what structural metals can. It’s not like we’d be totally fucked if the only abundant deposits of structurally useful metals in our planet were in the core (without a liquid ferromagnetic core we would be fucked), but we’d be relying pretty heavily on wood and stone for building which would prevent the massive structures that define our current artificial environment

                One thing that would have been really tough would be high-temperature pressure vessels, like for heat engines. Other materials with good tensile strength exist (as do wood skyscrapers!), and so do refractory materials, but if you need both at the same time you’re looking at either high-tech ceramic composites or metal.

                Does silicon even form metallic bonds?

                Uhh, not sure. The band structure of the crystal lattice supports conduction like a metal, but not without an impurity to introduce the initial carrier, which is the whole thing behind why it’s useful for electronics.

                IIRC bond type is kind of a continuum.

          Copper has chemical properties such that you can dissolve it, and then electrolyise it back out of solution ridiculously pure. More reactive metals stay in the solution, less reactive metals like gold, silver, cadmium and platinum form a nice little lump of sludge beneath your anode that’s absolutely worth collecting.

          It’s valued per weight, like anything else. Wire will cost around as much as the copper inside does, plus a little for the cost of extruding and coating it.

          TL;DR no, in the 21st century pure copper is just pure copper. If you make bronze then sure, there’s many different kinds.

          Iron is in rocks, potatoes have to be lovingly nurtured over a few months. That still doesn’t seem like enough to make up the difference, though. Preparing chips must cost more than smelting. I guess shipping is also a factor unless you’re near a chip factory.

            It’s also about scaling. For relatively little other than electricity and the price of some big slabs of brick and metal, you can make a foundry. To make potato chips, you have to have a lot more care, and the processes are much more finicky.

              Well, there’s a lot more to foundries than that. Safety with a liquid that explodes anything moist including people on contact and can start a fire remotely is a big one. Liners and molds are usually disposable too, and you generate several tons of spent material for every ton of product. But yes, heat, reducing agent (usually coal, increasingly hydrogen) and common minerals are the basic things involved.

              Then again, nothing about the process is delicate, and you don’t have to worry about sanitation or spoilage.

                Absolutely. I was being reductivist. The point I was attempting to make was that, whereas potato chip scaling must, at some point, involve quality control very close to the per-chip level, quality control at the foundry level can be applied to a batch which scales to whatever size you can pay for. Iron is iron, and that iron is largely similar to any other iron. It’s the same reason why chemicals which can be processed in a vat can be made much cheaper by just… Getting a bigger vat to synthesise more at once, while produce is a finicky business, because each item is not only individual, but unique, and thus must be handled at the individual level at some point in the process, even if it’s just a computer vision algorithm sorting which potatoes have already gone bad. Is that an inaccurate assessment?

                A sort of “juice is cheaper than the oranges you use to make it” deal.

                Of course, I also left out the price-fixing cabal which artificially inflates the prices of potatoes grown in the US.

                  No, it’s not. Although honestly we’re reaching the end of my knowledge about potato chip factories. And orange juice. Obviously the inputs to the process have to cost less than the outputs, but it does get pretty cheap.

          you should also consider the volume of a pound of each. the density is a big factor, depending on what kind of chips you refer to (a pound of crisps chips is a lot vs. a pound of steel, for example).

            I think they may have meant chips as in crisps. The trash food some of us occasionally get cravings for. Which are like 10-30 euros a kilogram these days. More expensive than steel, which is quite a bit more useful.

      Basically always has been since the industrial revolution, it’s also the reason why it gets recycled at much higher rates/more effort goes into gathering for recycling than steel (or rather how restricted the supply of new ore is compared to iron).

        A contract is only good if it is enforceable. If you order from China through something like alibaba, you have zero enforcement capacity. The only hope you have is that they will honor their contracts so people willl keep doing business with them. But there’s plenty of examples of that not happening so it’s pretty stupid to rely on it for a big order (‘big’ being defined by how much you can afford to lose).

            You may not like their writing style but they have a point. I worked at a place where China made wearable components for machines. The material was an aluminum bronze alloy, every once in a while they’d slip in a batch of steel painted to look like aluminum bronze, and hope nobody caught it before full payment

            And a family member worked at a major heavy equipment manufacturer that had axles made in China. It goes well for a while and then they secretly change material or heat treat process, and you find out 12 months down the road when all your equipment suddenly had a high failure rate in the field.

            My Asian friends said its part of the culture there: to do what you think you can get away with.

            I can’t verify that since I haven’t lived there, but even their government tries to scam people from other countries.

      If you don’t watch, why do you comment on it? You couldn’t buy copper in europe due to a shortage, everyone was buying it because of expoding prices. He split the purchase of 200 copper plates to two different suppliers. The scamers had 5 and 8 year old accounts on alibaba with over 100 verified trades, which gave an initial sense of security. Good luck suing two chinese scam companies, that’s just a waste of money and time.

        If you don’t watch, why do you comment on it?

        I wonder if it’s because Invidious doesn’t load the video and a lot of foks don’t like to support Alphabet, but are otherwise curious about the details of the photo that lacks much info.

        Hey, I can comment on titles if I want. Videos are just so slow, I can’t stand them.
        I guess when you’re desperate you use alibaba, but it’s hardly a news item when you get scammed.
