So I was gettingmy pizza out of the oven a few minutes ago and I went to grab the aluminum foil and it wasnt hot, it was barely warm. The pizza was nice and toasty, but the foil wasnt. ANybody know why this is? I thought ti was really weird.

   

Very thin with lots of surface area so it cools very fast.
If it was thicker, it would hold the heat better and you'd burn fingers.

   

I dunno, I dont think it would lose the heat that fast.

   

Crunch it up into a tight little ball and do the same thing.
I guarantee that a block of aluminum holds heat better than a thin sheet.
Call me old school but I'd go with thermal mass any day.

   

A thin sheet of aluminum works better to shield a wall from a wood stove than a thick sheet of anything.

   

Aluminum conducts heat a great deal better than all other common metals except silver, copper.
If copper is 100%,
Silver is 110%
Alum is 52%.
Steels is somewhere between 6-12%
It's also reflective so it does not absorb heat as much.

(good old Wilki hand book)

   

Hmmmm neat.

   

Ok. It's all bullshit.
Turns out my evil master, Stephan Lothar Harper made this pact with the devil and the ability of Aluminum to retain heat was one of the things he gave up. I don't recall the details because it was some king of package deal with George Bush and some bunnies or something.
Aluminum has protested this as a civil rights case with the supreme court but they will need good lawyers and have to prove that Aluminum, or "Al-U-minium" as they were known then, was at the Hindenburg fire. Should be easy because the statute on material properties is only 25 years, but it will leave them open to that UK ship that caught fire during the Falklands. They will also get a lot of support because without heat, you can't weld or cast anything.

   

lol very nice

   

does anyone else still call it tin foil....lol

   

Thermal Conductivity of metals in descending order.

Silver 1.0

Copper 0.94

Gold 0.71

Aluminum 0.57

Tungsten 0.40

Magnesium 0.37

Zinc 0.27

Nickel 0.22

Iron 0.18

Platinum 0.16

Tin 0.15

Lead 0.08

Titanium 0.04

   

So why dont we make foil out of copper more, I dont know that much about metals, but if they make pennies out of it it cant be that expensive.

   

Costs too much, which is why they don't make pennies out of copper anymore.
The copper was worth more than one cent.

   

Huh iiiiiiiiinteresting.
