there was no known technology that could safely allow microwaving metals. Microwaving metals is generally considered hazardous and can lead to fires, explosions, and damage to the microwave oven.
Microwaves work by emitting electromagnetic radiation that excites water molecules, causing them to vibrate and generate heat. Metals, on the other hand, reflect microwaves rather than absorbing them, which can lead to electric currents in the metal objects. These electric currents can cause sparks and arcing, leading to potentially dangerous situations.
The design and safety features of microwave ovens are specifically intended to prevent the microwaving of metals. If a technology were to be developed that could somehow mitigate the risks associated with microwaving metals, it would require significant advancements in microwave technology and safety measures.
It's important to note that even if such a technology were theoretically possible, there would still be practical considerations and safety concerns that would need to be thoroughly addressed before attempting to microwave metals. Until then, it is recommended to follow the manufacturer's guidelines and safety instructions for microwave use, which typically advise against putting any metal objects inside the microwave.
