    Haha, yeah the fun factor is definitely there - when else do you get to mix fun with molten metal and fun with water?

    Tobho had learned to work Valyrian steel at the forges of Qohor as a boy. Only a man who knew the spells could take old weapons and forge them anew.

    How was the sample prepared, was it a chill cast spectro disk, or just a hunk of sand cast metal?

    Sample prep method makes a difference in the lower concentration elements

    They have a lot of elements reporting on their spectrometer, Gallium, Cobalt, Scandium are pretty esoteric - wonder what weird alloy they cook up with those in it - aerospace shop by any chance?

    Surprised to see Silicon at 11%, would have expected 6% from American made wheels - possibly European castings?

    Just a blob that melted out. He ground it flat, and laser shot it. I actually didn't ask too much about it, but I should in the future because it sounds like fun.

    The rims were from a 93 Mazda and 05ish Jeep, if Chrysler was still with Mercedes then, it could be euro casts. And yes, that shop does do quite a bit with aerospace.

    Those are the aluminum reference lines used. The number is the wavelength in nanometers.
