    Bitch, you came looking for silver and found gold.

      She recognized the gold.

      She now wants his filthiest pickup line.

        You need to be able to pick the recipe option then. If someone knows recipes from ancient Rome, they might just be a harmless history nerd. If someone knows recipes from WH40K, well, I don’t know what to say.

          Wouldn’t 40k, depending on who and where, be something like, “Open meal package. Place 200g water in package. Close package and shake for 40 seconds. Open package and eat.” Civilian worlds you can just make up whatever, just like the scenario designers do. Want a US-lite world? Got one. Want a world reminiscent of 1800s UK? Got two.

    Is this actually true? Because all the YouTube videos I’ve seen of people trying to make iron in primitive ways have the issue of too much carbon in the iron. This causes the iron to be very brittle and hard to work. The trick about making good steel is to get just the right amount of carbon.

        You know you are in for a good time when you get to the chapter called “Sexual connotations”.

        I’m not an expert on the field, so I’ve read the paper, but am not qualified to draw conclusions from it. But as I read it, the focus is more on the role of ritual and religion in the making of the iron. And the transfer of knowledge through this process and hypothesize the addition of the burning of bone is actually beneficial.

        However they do not approach this from a material technology standpoint. So I would love for someone with knowledge on this point to chime in. It’s very interesting if the people back in the day knew how to make low carbon iron and the little bit of carbon they did add came from the burning of the bones. But as I see it the burning of the bones is more a ritual kind of thing and getting all of the carbon out of the iron is the harder thing to do, not putting the carbon in.

          Bone char isn’t super high carbon, so it’s possible that either the calcium phosphate or calcium carbonate is playing a roll.

          But honestly, you’re probably not getting very much of it mixed in from primitive smelting or forging methods.

            I am by no means a material scientist or biologist, but I have studied a lot of them and have some curiosities.

            It would be interesting to see how calcium doping modified the properties of the alloy. AFAIK the temperatures that iron smelts at is to high for the carbonate or phosphate bonds to remain stable, so most of it should have ended up as free calcium or phosphorus.

            I also imagine that the type of bones have a lot to do with it, since avian bones have a different composition and density than say, a moose bone. Different kinds of animals also have evolved different metal doping concentrations.

            Low carbon is actually a good thing to help avoid including too much and making the steel brittle.

      Also remember that carbon is lost as the metal is worked, so the strength can be increased simply by working the metal longer. This is how wrought iron is produced, although wrought iron ends up having a much lower carbon content in the process of removing slag.
