Microwaves cook rapidly using high-powered radio waves. They accomplish this by radiation, which also causes solar heat.
They bombard food with brief, energetic radio waves. Reflective microwave interiors enable radio waves to bounce around and go into food, vibrating molecules.
Water, lipids, and sugar can absorb radio waves, while plastics, glass, and ceramics can't
Metal reflects radio waves, preventing food from heating. Al foil? Thinner implies it may catch fire in the microwave.
You may microwave aluminium foil with specific care.Smooth out wrinkled foil.Fresh foil won't have creases, reducing fire danger.
Use smaller plates to keep a 1-inch barrier between foil and the microwave's walls and ceiling.
