There are a few items that you should never place in the microwave. These include:
1. Aluminum Foil
2. Glass Containers
3. Plastic Containers (unless they are labeled microwave safe)
4. Styrofoam Containers
Aluminum foil is one of the items that should never be placed in the microwave. When microwaving food, aluminum foil can cause sparks and even start a fire. Additionally, the heat from the microwave can cause the aluminum to leach into your food, which is not healthy.
Glass containers should also be avoided when microwaving food. Just like with aluminum foil, glass containers can cause sparks and fires in the microwave. In addition, glass can break and shatter when heated, which could lead to injuries if you're not careful.
Plastic containers are another no-no when it comes to microwaving food. Some plastics can release harmful chemicals into your food when heated, so it's best to avoid them altogether. If you do need to use a plastic container, make sure it is labeled microwave safe.
Styrofoam containers should also be avoided as they are made from polystyrene foam, which can release harmful chemicals into food when heated up in the microwave.
