In fact, having a microwave It requires certain precautions that sometimes go unnoticed and lead to serious accidents, such as poisoning.
In other words, there are ways of use that can guarantee your safety in the kitchen, by reading this article you will understand why. that you can't put in the microwave and we can put it on, but let's understand how this device works!

Understanding how microwaves work and the reasons why certain items should not be placed
The microwave, as suggested by its name, emits the heat waves which acts on water, sugar and fat molecules.
And the Magnetron which makes the microwave heat waves transform from electrical energy to waves, with an average power of 2.45 Ghz. So, it works like this, the heat waves are directed to the food placed on the central plate, which needs to circulate so that they are heated evenly.

Therefore, to understand the items that cannot go in the microwave is that they are made with materials that undergo a reaction to this frequency of microwave wave emission, and there are situations where they block them.
This can cause contamination, risk of fire and explosions, strong odors and, of course, damage to your equipment.
What can go in the microwave?
There are many items that provide safety for using your microwave and to avoid any doubts about which ones can be placed, see this list:
- Glazed ceramics
- Absorbent papers
- Specific plastics for use in microwaves
- Porcelain and earthenware (except those with metallic finishes)
- Common glasses
- Refractory glasses
Doubts may eventually arise, but always follow this list that doesn't have any problem!
After all, what can't you put in the microwave?
Right now, we will take a detailed look at all the materials that can react and interact with the heat waves from your device.
So, find out what you can't put in the microwave to avoid accidents in the kitchen:
Certain types of plastics
Plastics composed of Phthalos, O BPA (Bisphenol A) and the Dioxin when in contact with heat, they release substances from certain plastics that may come into contact with food.
Thus, if consumed for many days, they can generate some endocrine deficits, affect fetal development, reproductive disorders and even be associated with the emergence of cancer cases.
Furthermore, certain plastics cannot withstand the heat of the microwave and end up melting or even burning to the point of causing fires.
There are plastic products that come with a symbol indicating that they are suitable for use on the device.
Therefore, only use them, because they were produced to withstand what the microwave offers and do not leave any risk of contamination.
Metals
Above all, do not put anything made of metal, aluminum, alloys, metallic finishes and derivatives. driving power that the metal has causes it to overheat, which poses a risk of fire, explosions and damage to the microwave.
If you have placed any metal material in the appliance and noticed that it no longer heats up, you need to request a technical support to analyze the case.
Even though there are details, such as metal alloys, rims and handles, they are enough to cause accidents. For example, those aluminum lunch boxes need to be transferred to a plate or container that can be heated in the microwave.
Cloth and paper
There are materials that are more likely to catch fire and cause fires, such as paper towels and kitchen towels. Therefore, do not put packaging containing this type of material in your microwave.
Just the absorbent paper can be placed in the device, which is used to clean the greasy dirt on it.
However, there are precautions when using absorbent paper, avoiding leaving it on for long periods when heating anything with it.
It is recommended to heat your food little by little, especially those that have a build-up of fat or liquid content that requires absorbent paper.
Polystyrene
Placing Styrofoam releases the styrene, being a component that causes cancer, and affects our endocrine system.
Certain pieces of glass and crystal
The most fragile glass and crystals or those fragments of recycled glass are susceptible to reacting to microwave temperatures and end up breaking. Therefore, opt for refractory glasses, made specifically for culinary use.
Vegetables with skin
The bark ends up becoming a type of packaging which easily accumulates heat. Now imagine if heat accumulates, the result of this could be an explosion, right?
To the potatoes, to the grape, you tomatoes and other options can do this and cause a real mess on the equipment.
If you've ever had surprises like exploding food that shouldn't go in the microwave, it's good to know how to do it. microwave cleaning.
Woods
Various types of wood end up drying out and cracking due to the heat that the appliance releases. In fact, there are cases where paint comes off and contaminates your food.

O Kitchen Manual loves to make your experience complete! That's why you should check out these other tips that are worth knowing:
- Never turn on the microwave without something to warm upr, the crossing of heat waves can cause damage.
- Whatever the noise, if it occurs noises not usual or the power varies, you should stop using it.
- The correct thing to do is to take only food to keep warm, with very rare exceptions, such as thermal bags. Materials that are not food contaminate or even leave odors.
- Do not leave your microwave near other equipment that work with the release of heat, such as refrigerators and stoves, to keep you safe in the kitchen, as well as preventing your appliance from getting damaged.
- Never place near electronics that emit the same waves as microwaves, it is very common to do this with cell phones. Therefore, do not repeat this because it can offer unexpected and dangerous interactions.
Anyway, you already know what you can't put in the microwave and use it with more peace of mind in your kitchen routine.
