A microwave warms dishes only in one case - if it is not suitable for this technique. A magnetron emitting microwaves causes the products to heat up, and from them the heat is transferred to the plates.
What is warming - food or dishes
The specificity of microwaves is such that they act solely on water molecules. Therefore, only products containing H2O are placed in the oven, if it is negligible, put a glass of water in the chamber. In normal mode, the dishes are not heated. Microwaves, bombarding Н2О molecules, cause their random acceleration - food is evenly heated. The dish simply transfers some of the heat from the meal, so it becomes hot.
If you put cold soup or meatballs on warming up and you find that the microwave oven heats the plate very much, and not the food, do not panic. Do you think the microwave broke? It's all about the dishes. If you carefully study the instructions, you can find tips and advice on choosing containers for microwave ovens. There is even special cookware on sale - if you have a microwave, buy yourself several appliances to warm and cook food without any problems.
Why is she warming
There are processes in the chamber that are completely different from the usual processing of food. Instead of heat, here are microwaves acting selectively. As mentioned above, only water molecules are their object. If you put oil in the oven, it will not heat up. Fresh food can be dangerous to eat, as with such a high processing speed, it is likely that many microbes will survive.
If you notice that the stove has become bad at heating food, it is possible that you are using the wrong dishes. Do not place containers in the chamber:
- made of metal;
- containing metal;
- having even a slight metallized coating.
The nuances of the dishware issue
You can’t put anything you want into a microwave oven. You need to either buy special dishes, or be sure to test plates and bowls for “tolerance” to microwaves. How it's done? You need to put the test object in the chamber, next to the cup of water and turn on the device. If the container does not heat up within a minute, it is suitable for further use in the microwave. When testing, you need to include maximum power.
The market is full of Chinese containers, positioned as special containers for microwave ovens. Such products should be treated with extreme caution - they often do not live up to expectations.
Good to know: sparks can also be observed with quality plates. Why? Most likely, their composition contains a small fraction of metal particles, which provoke a “firework”. You should not use such plates, sparking is an unfavorable process, which can lead to malfunctions.
What materials are prohibited
It is strongly not recommended to put in the microwave chamber:
- metal plates;
- thin glass and porcelain containers, especially with gilding (gold paint);
- crystal objects - they can have different wall thicknesses and defects;
- ceramics not coated with glaze;
- fusible plastic;
- disposable tableware;
- aluminum baking tins.
Which material is better
The most suitable material for microwave cooking is glass. Almost without heating, it allows you to easily extract food from the chamber. But not all glass is suitable: you cannot use thin glass or crystal, as they will certainly crack under the influence of microwaves.
Thick-walled plates from:
- faience;
- ceramics;
- porcelain.
The choice of dishes is an important point for the successful operation of microwave ovens. Using inappropriate containers will sooner or later lead to damage to the device. Be careful when choosing utensils, and there will be no risk of burning your hands.
