    • Thanks, Ken. Iridescence is what compelled me to make a photo out of this, though the shapes may be interesting enough to warrant one.

  3. As in, what is it? I’d tell you, but that would be too, too easy. 😉
    Crazy colors, great find! 🙂 Seriously, I have no idea what it is.

    • The colors are the effect of a thin film of oxidized iron on the steel. Thin films of this sort exhibit the same interference colors present in “my” Leptothrix discophora films. Here’s this from Wikipedia ( “Tempering colors are produced when steel is heated and a thin film of iron oxide forms on the surface. The color indicates the temperature the steel reached, which made this one of the earliest practical uses of thin-film interference.”

      • Well, the colors don’t interfere with me….seriously, it’s amazing the way you find this phenomenon is such disparate places. Here’s to wandering! And seeing!

        • My first acquaintance with interference colors was in high school; it’s what I did my physics project on. Sadly, my physics teacher died before I could tell him how it has stuck with me.
