    I think you’re right. I was curious, so I looked it up.

    The melting point of copper is 1,085°C, and judging from this chart, its definitely getting close:

      You ever see gas hookups in the US?

      We use black pipe for most of the run. Cast Iron. The actual hookup itself is a flexible pipe…SS or Aluminum I think. Been a long time since I had gas. Sometimes they have like a rubbery-epoxy-ish coating but I assume that’s now quite gone and stinky.

        Oh, huh. That’s interesting. I’m from the great white north, and our gas hookups are copper from what I’ve seen. If this is indeed iron, then the melting point would be higher: ~ 1,540°C.

        Interestingly that colour temperature chart is supposedly fairly consistent across different metals.

          Tbh I don’t know why we don’t use copper. I imagine because it’s more difficult to fuck up threaded and doped connections as opposed to soldered ones.

        Def not cast iron, cast iron is used for waste pipes and it’s brittle you could never get threads on cast iron. It’s actually steel even if we call it black iron. A lot of newer houses will run solid pipe from the main to a central location and build a manifold with corrugated steal (flexible pipes) run to the terminal points.
