It looks like some sort of wiring inside

    A steel wire brush isn’t.

    I was initially going to say “my hairbrush isn’t”, but I forgot plastic is largely made of carbon, so you’s still be right.

          As iron, unlike gold isn’t a noble metal, an important aspect is, you need carbon to make pure iron from the iron oxides in the iron ore: The carbon will react with the oxygen and pure elementary iron and carbon oxides are left.

            Pure iron is somewhat soft. To make steel, you typically add extra carbon to the iron, which results in a harder (though more brittle) metal.

              Essentially, you reduce the carbon content of the raw iron by blowing in oxygen until you have the desired amount of carbon left. I should have written ‘elementary’ iron instead of pure.

        And how do you make steel?

        I don’t. I have people to do that for me.

        (But to answer your question, with a small amount of carbon, sure, but in my opinion that doesn’t mean that steel is “made out of carbon” any more than we would say humans are made out of iron)

      To be fair, I’m only “right” pedantically. 😂 My understanding is rocks and minerals aren’t mostly carbon, but still contain it…
