Landlord, I think it's more important to understand the principle.
The food containers used in the microwave are very picky. Generally, ceramic (note not "enamel") or special plastics can be used. And not metal or enamel.
This is because microwaves will "short circuit" and reflect when they come into contact with metal products. If the food is heated in a metal container, the temperature of the food in the container will not rise even if it is burned for an hour, because the microwave will reflect all the food back immediately after encountering the metal container, and the food will not be heated by a heat source. The more dangerous thing is still to come, because the high-frequency microwave is all reflected back, which forms a "high-frequency short circuit" in electronic technology, which will cause the electron tube anode emitting microwaves to produce high temperatures, burn to redness and damage.
Microwaves are electromagnetic waves with extremely short wavelengths, ranging from 1mm to 1m and corresponding frequencies between 300 GHz and 300 MHz. In order to prevent microwave interference to radio communications, broadcasting and radar, there are four frequencies for microwave heating and microwave drying, namely: L-band, frequency 890 940MHz, center wavelength; S segment, frequency 2400 2500MHz, center wavelength; C-segment, frequency 5725 5875MHz, center wavelength; K-band, frequency 22000 22250MHz, center wavelength.
In household microwave ovens, only the L and S segments are used. Microwave is obtained by applying direct current or 50Hz alternating current to an electric vacuum device or semiconductor device, and using electrons to make special movements in a magnetic field. Magnetrons are used in household microwave ovens, through which electrical energy is converted into microwave energy.
There are two types of magnetrons: pulsed magnetrons and continuous magnetrons. Continuous-wave magnetrons are used in microwave ovens. Microwaves travel at speeds close to the speed of light, and they are able to reflect and refract during propagation, and it has three important properties related to heating.
When microwaves encounter metallic objects such as silver, copper, aluminum, etc., they are reflected like a mirror reflecting visible light. Therefore, metal-insulated microwaves are commonly used. In microwave ovens, metal is commonly used to make boxes and waveguides, and metal mesh and tempered glass are used to make furnace door observation windows.
When microwaves encounter insulating materials, such as glass, plastic, ceramics, mica, etc., they pass through as smoothly as light passes through glass. Therefore, insulating materials are often used to make discs without affecting the heating effect. When microwaves encounter watery or fat-containing foods, they are able to be absorbed in large quantities and converted into heat.
Microwave ovens use this property to heat food.
Therefore, the common utensils of microwave ovens, mainly including plastic products, ceramic products, glass products, etc., must at least be non-polar, and ceramic bowls with metal decorative rings are not allowed.

Yes, the main thing is to pay attention to the heating temperature should not be too high, it is best to control it at more than 90 degrees for about 5 minutes, and pay attention to stirring. Otherwise, the bottom will stick to the pot.

OK. If I use a compact box, breathing is necessary.

Milk can be boiled in an enamel pot.
The enamel pot boiled milk is very good, which can ensure that the nutrients are not lost, the enamel milk pot is corrosion-resistant, easy to clean, and the boiling time of the milk should not be too long, so as not to affect the taste of the milk, and the time of boiling milk should not be too long, so as not to affect the taste of the milk, and the milk can be drunk alone after cooking, or it can be eaten together with bread and other ingredients.
Introduction to enamel pots.
After boiling milk, there is no peculiar smell residue, hot milk can be used enamel cup, but it must be noted that if the enamel cup is damaged, the paint should be stopped, so as not to endanger the health of the enamel layer has excellent chemical stability, can effectively resist the corrosion of acid and alkali components, health, energy saving, environmental protection, non-toxic hygiene, the product is beautiful and colorful, and can be decorated.
Non-stick technology and PFO-free.
and its salts, high temperature resistance, corrosion resistance, durable and durable, healthy and hygienic, easy to clean, suitable for electric stoves, induction cookers.
Gas stoves and other stoves are resistant to high temperature and expansion coefficient.
It is extremely low, chemically stable, and will not allow the nutrients of milk to be lost, which is healthy and safe.
There is no peculiar smell residue after use, and it can be suddenly heated and cooled, that is to say, it can be taken directly from the refrigerator to the fire, saving fuel, and the enamel pot is visible in the pot refers to the pot made of enamel glaze on the surface of the metal body. It has the mechanical strength of metal and the physicochemical characteristics of enamel, and the enamel has the inherent mechanical strength and processing properties of metal.

Summary. 1. Ceramic cups can heat milk, but it is best not to use colored ones with inner walls, such as glaze color heating milk will harm the body.
2. Heating milk in a ceramic cup with honeysuckle lace will also be harmful to the body.
3. When heating milk in a ceramic cup, do not make the temperature of the cup too high, because the protein changes back in the case of too high temperature and loses its nutritional value, it is recommended to use a ceramic cup at room temperature to heat the milk is the most appropriate.
4. It is best to use glaze color and underglaze color ceramic cups to heat milk, which has a stronger ability to withstand high temperatures and will cause less harm to the human body.
Can milk be heated in a glass when placed in a porcelain bowl.

Dear, I've got it for you.
Hope it helps.

Yes, the porcelain hail sun destroys the bowl, and there is nothing to do with the source of the Kai cave.

Yes, just don't cook it.
No. Nutrients are lost after fresh milk is heated?
Some people worry that fresh milk will lose nutrients when it is heated, but is this really the case? In fact, milk can certainly be heated in moderation, but there are a few things you should be aware of. >>>More
You can use fresh milk as an ingredient for making yogurt. >>>More
No. We can usually add some white sugar in the process of drinking milk, but not brown sugar. Because brown sugar contains a certain amount of oxalic acid, when added to milk, the rich protein of milk will gel or precipitate under the action of oxalic acid, resulting in the loss of nutrients. >>>More
1. Can peanuts be heated in the microwave?
Peanuts can be heated in the microwave, but you need to pay attention to the heating time and heat, generally fresh peanuts, we put them in a suitable container, and finally put them in the microwave oven for heating, try to choose medium and high heat, the heating time is controlled as much as possible at about 1 2 minutes, and you can take out the peanuts and let them cool and eat them in a circle. Therefore, if you eat it when it is cold, the taste is the best. >>>More
Do not use cold water to blister, it will affect the formation of milk skin. >>>More
