I always thought wrought iron was just a fancy name for old steel

I was reading a book on historic metalwork from the library and found out wrought iron has almost no carbon, less than 0.08%. I'd been lumping it in with mild steel for years. The book explained that's why it's so fibrous and forge-welds differently. It totally changed how I look at repairing old gates. Has anyone here actually worked with the real stuff?

Wait only 0.08% carbon? That's basically nothing. I always figured wrought iron had to have some carbon in it to be workable but that's barely even there. So it's almost pure iron with just slag fibers running through it. No wonder it behaves so differently under a hammer. I've never actually worked the real stuff myself but I've seen guys try to weld old wrought iron with modern steel rods and it just doesn't take the same way. The fibers make it act like a completely different material. Makes me want to hunt down some actual wrought iron just to see what the fuss is about.

It's wild how many things we use wrong names for. Makes you wonder what else we're all just guessing about.

What if the wrong names actually help us learn things faster? Sometimes a catchy wrong name sticks better than the real one. That guesswork might be how language actually grows.

Oh man, I feel that so hard. I did the exact same thing with wrought iron for the longest time. Just called any old black metal "wrought iron" without a clue. It's like what @cooper.drew said, we guess about so much stuff. I remember learning that "tin foil" hasn't been tin in ages, it's all aluminum. Makes you stop and actually look at the old things, you know? That's cool it changed how you see fixing gates.
