1. Metal: An obvious danger, but not always remembered.

Metal objects Microwaves are sworn enemies.

This is one of the most widely known dangers, yet many people continue to ignore this basic rule.

When metallic objects are placed inside a microwave, the interaction with the microwaves can result in sparks that may cause fires or, at the very least, damage to the appliance.

Why is metal dangerous?

Microwaves heat food by causing the water molecules to vibrate.

Metal, however, does not behave in the same way.

Instead, it reflects electromagnetic waves, which can cause sparks and intense heat.

In utensils with sharp edges or thin surfaces, concentrated heat can result in a flame or even an explosion.

The use of aluminum foil, For example, it is especially dangerous, since this material can quickly cause a fire.

What metal objects do people usually forget?

Although many people know that metal pans shouldn't go in the microwave, there are smaller, less obvious objects that can be forgotten.

A classic example is plates or bowls that have metal rims.

These items are beautiful, but they can generate dangerous sparks if used in the microwave.

Additionally, some frozen food packaging may contain metallic coatings, so it is crucial to check the packaging before heating them.

Item	Why is it dangerous in the microwave?
Aluminum foil	It can generate sparks and fires.
Cutlery	They reflect waves, causing sparks and potentially damaging the microwave.
Dishes with metal rims	They can cause sparks and short-circuit risks.

2. Things that shouldn't go in the microwave: Plastics, The invisible danger

Plastic containers are a real challenge when it comes to heating food in the microwave.

Many plastics simply They weren't designed for that type of heating..

Therefore, improper use can release toxic chemicals into food or even melt the container, causing a mess.

BPA and other toxic chemicals:

Plastics contain substances such as BPA (bisphenol A), which can be harmful when heated.

When exposed to heat, these chemicals can leach into food.

Scientific studies indicate that prolonged exposure to BPA may be associated with health problems, including hormonal disorders, cancer, and developmental problems in children.

This is especially alarming with cheaper plastic containers or those not classified as "microwave safe".

Things that shouldn't go in the microwave: How to identify safe plastic?

Not all plastics are dangerous.

Some are specifically designed to withstand microwave heating, but it's essential to know how to identify them.

Check the bottom of the containers: microwave-safe plastics usually have a seal indicating that they are safe to use. “"microwave-safe"” or a symbol that looks like waves.

Additionally, the number on the recycling triangle can also provide clues – numbers 1, 2, and 5 are generally safer for heating.

Type of Plastic	Microwaveable?	Why?
BPA-free	Yes	Designed not to release toxins when heated.
PVC (number 3)	No	It can release phthalates that are harmful to health.
Polystyrene (number 6)	No	Risk of releasing styrene, a possible carcinogen.

3. Eggs: Please leave them out of the microwave.

If you've ever tried cooking a egg in the microwave, You've probably already figured out what happens: an explosive mess.

Cooking eggs in their shells, or even some types of whole eggs, in the microwave can result in an explosion due to the rapid increase in internal pressure.

Why do eggs explode?

The structure of eggs is the reason for their unpredictable behavior in the microwave.

In this sense, the egg white and yolk contain a significant amount of water, which heats up quickly.

Since the heat inside the egg does not dissipate evenly, the steam has nowhere to escape.

The result is an explosion that can soil the appliance and even injure someone if the door is opened before it cools down.

Safe alternatives for heating eggs

Instead of risking a microwave explosion, opt for safer methods.

For example, how to cook an egg in a pot of boiling water or use it in preparations that do not require direct heating of the shell.

If you are reheating already cooked eggs, poke holes in the shell or cut the eggs into smaller pieces to prevent pressure buildup.

Egg Shape	Microwaveable?	Risk/Alternative
Raw egg with shell	No	Explosion due to internal pressure.
Hard-boiled egg with shell	No	Risk of explosion upon heating.
Scrambled or sliced eggs	Yes	Provided they are in suitable containers.

4. Airtight containers: When isolation becomes a trap.

When heating food in the microwave, it is common to resort to containers with lids, mainly to prevent food from splattering and soiling the inside of the appliance.

However, the containers hermetically sealed They can represent a considerable risk.

The danger of pressure buildup:

When a container is completely sealed, the steam generated during heating has nowhere to escape.

The result is an increase in pressure inside the container, which can eventually lead to an explosion.

This not only damages the container itself, but it can also damage the microwave and, even worse, result in severe burns when opening the container after heating.

Things that shouldn't go in the microwave: Safe solutions

To avoid accidents with closed containers, the advice is always... remove or loosen the cap before putting them in the microwave.

If the goal is to prevent splattering, a lid specifically designed for microwaves, with steam vents, is a safe and effective alternative.

Therefore, remember to stir the food periodically to ensure even heating and reduce internal pressure.

Container	Microwaveable?	Risk/Alternative
Airtight container	No	Explosion due to pressure buildup.
Container with loose lid	Yes	It prevents explosions and splashes, while allowing steam to escape.

5. Thermal cups and food containers for takeout.

Another common mistake is putting thermal cups and some types of food packaging suitable for microwave takeout.

While these transport solutions are convenient for maintaining the temperature of food and beverages, they can be dangerous when placed in the appliance.

Many thermal mugs have a metallic coating, even if it's not visible on the outside.

When these cups are microwaved, the hidden metal creates the same dangers mentioned earlier: sparks, overheating, and damage to the appliance.

Additionally, some thermal plastic cups are not suitable for microwave use and may melt or release toxins when heated.

Takeaway food packaging, especially those with metal lids or unsuitable plastic coverings.

They can release unwanted chemicals when exposed to heat.

Furthermore, some styrofoam packaging can melt in the microwave, compromising the integrity of the food.

Item	Microwaveable?	Risk/Alternative
Thermal mug	No	It may contain metal, which could cause sparks.
Styrofoam packaging	No	It melts, releasing chemicals into the food.

6. Things that should not go in the microwave: Foods with peels and seals.

Fruits such as tomatoes, grapes and potatoes, In addition to foods with natural or artificial sealing.

For example, how sausages, They also pose risks when placed directly in the microwave.

Like eggs, foods with shells or seals create a kind of "barrier" that prevents steam from escaping.

When exposed to the intense heat of a microwave, the internal steam accumulates rapidly, resulting in bursts or explosions.

This can not only damage the microwave, but also result in burns or contamination of food with pieces of broken peel.

How to avoid problems with sealed food

The solution is simple: pierce the shell of the food before heating it.

This will allow the steam to escape in a controlled manner, preventing explosions.

Additionally, avoid heating very large foods for extended periods, as the heat may not be distributed evenly.

Food with shell/seal	Microwaveable?	Risk/Alternative
Whole potatoes	No	They explode due to the accumulation of steam.
Whole sausages	No	They can explode without proper drilling.
