The amount of heat reflected/absorbed between the two sides is trivially small.

Your particular choice of wording here makes me very curious: Do you mean that there really was a measurable difference (which was trivially small)?

[–] cooltrainer_frank@lemmy.world 103 points 4 months ago (7 children)

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.

Awesome!

Jokes on you.

I baked my casserole with the shiny side up and pulled it out at 59 minutes and 55 seconds, when it was supposed to go for an hour.

So take that Dull Side!

Welcome to the Dull Side.

Now that's the kind of industry secrets I opened this thread for.

Today I learned numbers are visuals but words are not. Wtf dude!

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.

[–] cooltrainer_frank@lemmy.world 8 points 4 months ago

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!

Post your spectral emissivity study or GTFO!

I mean, maybe if you bake a stone cold potato that was in the fridge and then cook it for two hours? But even then we're probably talking about a handful of minutes at the most.
