Does Aluminum Foil Burn?

Does Aluminum Foil Burn

We’ve been using Aluminium foils since the 1920s to pack our foods and now it has become a common kitchen staple in our kitchen. There are a lot of things that people still can’t figure out when it comes to using Aluminum foil. One of the things people wonder is whether or not Aluminium foil burn. In this article, we are going to answer this question in detail.

So, can aluminum foil burn? No, Aluminium foil doesn’t burn. Since the ignition temperature of the aluminum foil is 1,220 degrees Fahrenheit (660 degrees Celsius) which is pretty high to achieve in an oven or a gas stove, the Aluminum foil does not burn easily.

The aluminum molecular structure is in such a pattern that its molecules are tightly packed which requires high temperature to burn it. Although, aluminum in powder form is easily combustible. One of the examples of powder Aluminium combustion is thermite welding where Aluminium powder is used with Ferric oxide.

Can you burn aluminum foil with a lighter?

Many experiments have been performed to burn aluminum foil with a lighter, But it is not possible to burn it clearly with a lighter as lighter cannot reach up to the required temperature.
So, we can say that aluminum foils slightly have any physical change on exposed to lighter.

There are actually some lighters that are capable of providing flame temperatures up to more than 1500 degrees Fahrenheit which is above than melting point of the aluminum (1220 degrees Fahrenheit).

Even though these lighters have a high temperature but still, they can’t provide enough BTUs (traditional SI unit of heat) to melt the metal.

An example of such lighters is butane lighters that have their flame temperature of 4074 degrees Fahrenheit.

Does aluminum foil burn on the stove?

Does aluminum foil burn on the stove

An electric or gas stove cannot meet the temperature up to the temperature required for melting the aluminum foil. A stove doesn’t burn aluminum foil. These appliances are mainly for heating the food items that can reach a max temperature of around 185 -190 degrees Celcius.

Does aluminum foil burn-in microwave?

A microwave is a great invention and it came into commercial use since the 1970s. It can be found around our homes, offices, etc. One simple precaution is generally told regarding the use of microwaves is to avoid putting any metallic utensils inside it.

We should not put any metallic object including aluminum foil inside the microwave because this appliance emits radio waves to heat up the food item. Microwaves are the radio waves falling under frequency around 2500 megahertz. And any metallic object detected by radio waves inside the microwave acts as a reflector of radio waves.

If food placed in the microwave is put inside the metallic pan, It will not be cooked properly because the pan would guard the food item against the microwaves.

Is it safe to cook with aluminum foil in the oven?

No, It is not safe to cook with aluminum foil in the oven. It is strictly restricted to put any metallic object inside the oven or microwave. One reason is that food will not be cooked properly if food is covered with aluminum foil.

Secondly, the thin aluminum foils can heat up quickly because of the electric current caused in them due to the electric field generated inside the oven. Moreover, if the foil is in the shape of sharp-edged as crinkled. The electric current flowing through the foil can cause spark too which can cause a fire. Therefore, it becomes dangerous and risky if anyone unaware of these instructions uses aluminum foil while heating foodstuff.

Some dangers in using aluminum foil in Oven and Microwave

Spark in the appliance: The aluminum foil in sharp edge shape as crinkled form present inside the oven can cause spark because of the heat due to electric current flowing through it. The spark can cause a fire inside the oven which can lead to a dangerous situation for you.

Overheating: The aluminum foil is a good conductor of heat. Therefore, it is used to cover the food items which can retain warmth for a longer. If aluminum foil is also present inside the oven or microwave, it is more likely to increase the temperature of the oven which can reduce the life span of your microwave or oven.

Health risk: Many people use aluminum foil for roasting vegetables or baking fish because of its high thermal conductivity. So, aluminum foils are used in baking, cooking, and grilling over many parts of the world. But this leaches aluminum content into the food item which can cause health problems.

Safety Tips

Electric Oven and microwave: Never wrap or cover the food item with aluminum foil while putting it inside the microwave and oven. The food will not be cooked properly as explained above and also the chances of mishappening of a spark causing fire increase for you.

Gas cooktops: Never cover the holes, grates and line part of the cooktop with the aluminum foil. The main reason is that it can overheat the upper surface of the cooktop and also it can cause poisoning of the carbon monoxide gas.

We should use aluminum foil properly as Improper use of this can damage your electric oven and microwave. These appliances are prone to fire and short circuits in such cases.

While buying an electric oven or microwave, the special utensils which are marked “microwave safe” are given as accessories to the customers at any stores over the world.

These utensils are made up of polypropylene, ceramic and inner part of stainless steel.

Utensils used for microwave/Oven

Ceramics: There are many glazed ceramic pans such as lasagna pans, quiche pans, tagines, etc which are used for microwave/Oven.

Glass: Borosilicate glass pans can also be used for heating food items in the microwave. However, the normal glass should not be used for this purpose because it is too thin, it can shatter.

Silicone: Food- grade silicone pans are best for use in microwave/oven and also these pans are indestructible.

Wood: Wooden pans can be used in microwave only for short term heating.
