    Yup, the lab could tell a difference! Shiney side (so mill roller facing, as opposed to the dull side which faces the other layer of aluminum) was marginally more reflective, but I believe (and a former coworker also remembered it as) it was less than a tenth of a percent (<0.1% for the visual folks)

    Anyone who says it affects cooking time or something is mistaken, I’d wager.

      Any info on surface roughness? I’m thinking shiny side would be smoother and therefore less sticky, though I don’t know how much the passivation layer would affect it. Probably no where close to making a difference at the end of the day, but I’m curious.

        It was a fair few years ago, but yeah, the oxidation on it will be so much smoother than the delta in surface roughness that I doubt it’d make much difference. Lemme reach out to a metallurgist from there and see what he thinks!
