Background

With the gradual development and progress of science and technology, the living standard of people is gradually improved, and the ownership rate of families to microwave oven products is increased year by year. In the daily use process of the microwave oven, if food is placed in the metal container for heating, even if the food is burnt for one hour, the temperature of the food in the container cannot rise, because the microwave is completely reflected back immediately after meeting the metal container, and the food cannot be heated by a heat source. Even more dangerous, the high frequency microwaves are totally reflected back, which creates an electronic "high frequency short circuit" that can cause the anode of the tube emitting the microwaves to generate high temperatures that burn to red and damage the tube. Food containers for use in microwave ovens are critical and can generally be made of ceramic or specialty plastics, but not metal or enamel.
