Why does aluminum foil have one shiny side and one with a matte finish?
- dnemmers 9mo ago“The final rolling is therefore done on a sandwich of two sheets, face to face.”
- slau 9mo agoWhomever wrote that clearly has never made or eaten a sandwich. Without something in between the two layers, it’s hardly a sandwich.
- mjevans 9mo agoThe foil is the 'meat' the rollers are the bread.
- perilunar 9mo agoAn open sandwich can have two layers.
- volemo 9mo agoNot homogenous though.
- perilunar 9mo agoIf it was any more homogeneous it would just be a piece of bread.
- socalgal2 9mo agothat's not a sandwich, it's a pizza
- perilunar 9mo agoA pizza is an open sandwich
- ekropotin 9mo agoNo, pizza is a toast per Cube Rule - https://cuberule.com/ https://cuberule.com/
- CoastalCoder 9mo agoWhat if the pizza has a stuffed crust?
- perilunar 9mo agoToast is an open sandwich, unless it has no topping, in which case it is just bread. Also their definition of cake as having multiple layers makes no sense, and would rule out most actual cakes.
- notpushkin 9mo agoIf you take a closer look at the examples again, you’ll see that nothing makes sense. That’s the joke. (Steak is definitely a salad, though.)
- doodlebugging 9mo ago>An open sandwich can have two layers.(..) ...and if one layer is meat and the other is a perfect meat vehicle, like a tortilla, you can simply fold it over the meat and wrap all the meat goodness is the proper warmth of a tortilla. Food, the way food was intended.

- jgwil2 9mo ago*Whoever wrote that. The person who wrote is the subject of that phrase, not the object.
- slau 9mo agoThanks! That’s one rule I keep forgetting, but I’ll try to make an effort. Unfortunately I can’t edit the post anymore.
- qingcharles 9mo agoTo quote the Blues Brothers, that's a "wish sandwich", when you have two slices of bread and you wish you had some meat.
- CLPadvocate 9mo ago> Yet many people persist in calling aluminum foil "tinfoil." > We chemists get annoyed at things like that. > Now, about aluminum foil. Actually, most chemists are profoundly annoyed at the Americans' inability to spell aluminium properly...

- antonvs 9mo agoDid visiting the moon damage your hearing? Last I checked there haven’t been any Americans on the moon for over half a century. Perhaps if you used the metric system…
- hacker_homie 9mo agoThey do use the metric system at NASA maybe that’s why they haven’t been back to the moon.
- johng 9mo agoI always heard the shiny side reflected heat better. So that side should face food you are trying to heat up in the oven. Any truth to that I wonder?
- ahhhhnoooo 9mo agoNo. Aluminum foil has the same material properties with respect to convection and conduction of heat no matter which side faces out. The only heat that would be different would be radiated heat, which your food won't have a ton of, and even then, the dull side is still quite reflective. It's maybe one of those "technically" correct statements that the shiny side reflects more heat, but for the application of cooking, the impact is effectively zero. The retention of steam is going to be such a larger factor the side you use will effectively make no difference.
- hamstergene 9mo agoI can speak for myself: when I ask if the shiny side reflects the heat better, I don't mean to also ask if the difference is significant. It's really just curiosity, whether my school physics intuition holds up or lies to me, that's all. So, "technically yes" is good enough answer for me.
- sdeframond 9mo agoIs it technically true, though? The matte side has a difuse reflection, which does not mean it reflects less. It just scatters more.
- bob1029 9mo ago> The only heat that would be different would be radiated heat, which your food won't have a ton of Your food won't radiate much heat, but your oven certainly does. Aluminum + broiler is like photolithography for food.
- sawjet 9mo agoThe shiny and dull sides look like perfect mirrors in IR wavelengths.
- rich_sasha 9mo agoWhich side is better at reflecting woke beams from space?
- NewCzech 9mo agoPeople deeply understand the physics of tinfoil hats. A properly constructed tinfoil hat needs two layers, with the shiny sides facing in opposite directions. Only the shiny side reflects brain waves. You need to reflect in both directions: one direction keeps the government from using waves to put ideas in your head; the other is to keep the government from reading your mind.

- botusaurus 9mo agoso if you skipped the final rolling it would be shiny on both sides? is this being produced?
- gethly 9mo agoaluminium :D
- undebuggable 9mo agoShiny side is for wrapping the end of banana, the matte for the other end.
