As a material science expert with a focus on household safety and efficiency, I've spent considerable time examining the use of various materials in the kitchen, including the use of aluminum foil in microwave ovens. Let's delve into the safety and practicality of using aluminum foil in a microwave.
Firstly, it's important to understand that microwaves are a form of non-ionizing radiation. This means they do not have enough energy to ionize atoms or molecules or to break the chemical bonds in food, which is a good thing because it means they are not capable of causing the kind of damage that can lead to cancer or other health issues.
However, when it comes to using aluminum foil in a microwave, there are several factors to consider:
1. Reflection of Microwaves: Aluminum foil is a highly reflective material. When microwaves encounter aluminum foil, they are reflected rather than absorbed. This can lead to what is known as "hot spots," areas in the microwave where the energy is concentrated, potentially causing uneven heating.
2. Sparking: If the foil is crinkled or folded in a way that creates sharp edges, it can potentially cause sparks when exposed to microwaves. These sparks can be a fire hazard and are generally something to avoid.
3. Melting: While aluminum foil has a high melting point, the heat generated in a microwave can cause the foil to become hot enough to burn skin upon contact. Additionally, if the foil touches the microwave's walls or ceiling, it can cause damage to the oven's interior.
4. Complete Coverage: As mentioned in the provided reference, no food should be completely covered by aluminum foil or placed in a covered metal pan when microwaved. This is because the microwaves need to be able to penetrate the food to heat it effectively. If the food is completely enclosed, it can lead to uneven heating and potentially damage the microwave.
5. Proper Use: Despite the risks, aluminum foil can be used safely in a microwave if handled correctly. It should not be used to completely enclose food, and it should be smoothed out to minimize the risk of sparking. Small slits or vents can be made in the foil to allow steam to escape and microwaves to penetrate the food.
6. Alternatives: For those concerned about the safety of using aluminum foil in a microwave, there are alternatives such as microwave-safe plastic wrap or parchment paper, which can be used to cover food without the risks associated with metal.
In conclusion, while aluminum foil is not inherently unsafe for use in a microwave, it requires careful handling to avoid the potential hazards associated with its reflective and conductive properties. By understanding and applying the proper techniques, one can safely and effectively use aluminum foil in a microwave environment.

No food completely covered by aluminum foil or in a covered metal pan should be put in a microwave oven because food wouldn't be available to absorb the microwaves. Operating the oven empty or when the food is completely wrapped in aluminum foil can cause damage to the oven and the food won't heat.Aug 8, 2013
