  • To expand on this, the rainbow of colors which start at a straw then turn yellow, red, brown and then that vivid blue, are caused by refraction. The oxide layer on the surface is transparent or translucent, and the thickness of the layer determines what wavelength of light it scatters. The hotter it gets, the thicker the oxide layer forms, so you can fairly reliably tell the temperature the metal has been heated to by eye, and you might use different amounts of heating to achieve hard-but-brittle or soft-but-tough.

    I’ve even seen it done by Chris of Youtube channel Clickspring for decorative purposes. It’s how he made the steel hardware of his brass clock blue.

  • Can anyone name me one that is a normal fucking car? With a little dial that tells you how fast you’re going that isn’t an LCD display that can’t be read in direct sunlight connected to an internet connected computer that will never get OS updates? With a gear shift lever that moves forward and back or up and down to select park, reverse and drive, not a nipple in the glove box to lick for “Forward,” a knob on the ceiling labeled “H” and to put it in reverse you honk the word REVERSE on the horn? Where the doors have handles that you pull on to open that look like door handles, and locks that have cylinders that accept keys?
