1, microwave can't penetrate metal objects, but it will reflect back when it meets metal objects. The outer packaging of eight-treasure porridge is metal, so it can't be heated in microwave oven.

If the metal is put in the microwave oven, it will absorb the microwave of the microwave oven. After the metal absorbs microwave, it will be excited by electrons to generate a large current, which will release an electric spark between the metal vessel and the furnace body, and even burn the furnace body or vessel in serious cases.

You should pour the eight-treasure porridge into a container suitable for heating, and then heat it in the microwave oven. Be careful that the heating time is not too long, just two to three minutes, so that a bowl of delicious eight-treasure porridge can be heated. Canned eight-treasure porridge can't be directly heated in microwave oven or other heating appliances.

Matters needing attention in the use of microwave oven:

Avoid metal utensils.

When heating things in a microwave oven, the utensils for holding food must be non-metallic materials, such as glass, ceramics and high-temperature resistant plastics. If it is a metal container for holding food, the metal container will reflect microwave after being electrified, which will interfere with the normal work of C in the oven, produce high frequency and short wave and damage the microwave oven.

Avoid heating frozen food directly.

Frozen food cannot be directly heated by microwave oven. Frozen food should be thawed first, and then heated and cooked to avoid the phenomenon that cooked food has different degrees of maturity inside and outside. Pay attention to the size and thickness of food, and don't differ too much.

Avoid heating food in closed containers.

In the use of microwave ovens, do not use closed containers to hold food, because the heat generated by heating food in closed containers is not easy to dissipate, which will increase the pressure in the containers and easily lead to explosion accidents. In addition, during the heating process in Weibo, stay away from the microwave oven for a period of time to prevent accidents and injuries to yourself.
