However, it should be noted that there is a triangular arrow outside, and there is a plastic box made of PP with the number 5 written on it, which can be heated by microwave oven. In addition, special containers of porcelain, pottery, heat-resistant glass, polypropylene and polyethylene can be used for microwave heating.
Need special attention:
Avoid using ordinary plastic containers, metal containers, porcelain with metal edges and closed containers in microwave ovens. Ordinary plastic containers are easily deformed when heated by microwave oven.
When metal utensils are heated in the microwave oven, it will produce electric sparks to reflect microwaves, which is easy to cause fire hazards. When a microwave oven heats a closed container, the inside of the container is heated to produce pressure, which is easy to explode if the pressure is too high.
