Whenever I cook pizza in the oven i put it on tin foil. I've noticed that when im done cooking the tin foil is never hot. The cooking tray i put the tin foil could melt your skin off but the tin foil isn't even warm.

Tin foil/aluminum foil DOES get hot when it goes in the oven...
HOWEVER, it has a very low Specific Heat Capacity. This means that it takes almost no time to heat up and almost no time to cool down again. The foil wrap is very thin and has very little weight to it so it is cooled extremely fast. If you put a brick of aluminum in the oven (rather than thin foil) or a tray made out of aluminum (like your cookie tray), you would definitely notice how hot it got (and how slowly it cools) down compared to the foil.
Water, on the other hand, has a very high specifici heat capacity. Thus, it takes awhile to heat up/evaporate and awhile to cool down. Humans are made up of a LOT of water so this is why we can handle cool days and hot days on the beach without freezing or evaporating away.
Hope this helps you understand!
Cheers :)

Here is the REAL answer: All materials have the ability to hold heat. It's called heat capacity. Aluminum has a lower heat capacity than water, so what heat *does* get into it will be quickly released when the aluminum gets into a colder environment (outside the oven). That, and consider that it is only foil -- a very thin piece of material -- not much *material* to hold heat in the first place. Even if it had a high heat capacity, the fact that there isn't much of it there to begin with (very thin), means there isn't much heat inside the foil to keep the temperature high for very long. I just used that principle to pull a braised roast (in foil) out of the grill last weekend -- knowing that the foil would be cool enough to touch in a matter of seconds after opening the lid to the BBQ grill. .

Im sure someone has already mentioned this as I am late, but aluminum foil does get hot, it just cools quickly. If a frozen pizza is on the foil in the oven, the foil will be fighting conduction of cold and heat. Its a metal. Try putting the foil in the freezer for 30 minutes. Same effect.

Anything sitting in a hot oven tends to reach the same temperature as the oven high. When the oven door opens, that aluminum foil is at the same degrees as the oven. However, aluminum foil is very thin. There is very little actual aluminum and it is spread over a relatively large area (standard aluminum foil is about 0.0007 inches thick; heavy duty foil is about twice as thick). As a result cool air outside the oven cools the foil quickly. If you grab the foil with your fingers, rely on the cool room air to cool the foil surface quickly to keep from burning oneself. Also fingers themselves have a lot more mass than the aluminum foil that you are in contact with so usually only the top surface of the skin would be heated. Water on the surface of hands will also cool the foil.

Specific Heat Of Aluminum Foil

Certainly Aluminum foil gets hot, very hot, as hot as any other metal but the reason you think it is not, is due to the physical property called mass. The greater amount of mass, the longer it takes to heat or cool. Very little mass is used in various foils, whereas your cookie sheet is several hundred times thicker, thereby providing a greater mass which retains the heat longer. That was a great symposium on Microwaves Neema. Thanks. And love the Tin man ...er SuperTinMan..... I wonder, was Rin Tin Tin a metal dog? lol

Tin foil (or more properly, aluminium foil) is an awesome conductor. That means that it transfers the heat in your oven through to whatever it touches. However, once it is removed from a heat source, that very conductivity means it cools down superfast, and when you bring it out of the oven it almost immediately returns to the ambient room temperature.

The foil does get hot, as hot as the rest of the oven. But the material is so thin, that it cannot retain heat for very long. If you were to use a much heavier duty foil you might feel the heat a bit longer.

I don't know what kind of oven you're using, but any time I put tin foil in any type of oven, it gets hot along with whatever I'm cooking/re-heating.

It does get hot. The thing is that it is so thin that as soon as you take it out of the oven, all the heat dissipates and it feels cool. If you put your hand in the oven quickly and tough the foil, it will burn.

If you touched the foil while it was in the oven, it would be very hot - just as hot as the pan.
How, it quickly loses temperature when you remove it from the oven and becomes the temp. of the air.
