Only tin foil can be used when the microwave oven has barbecue function and light wave function; You can't use tin foil with microwave function!

Because the heating principle of microwave is different from barbecue and light wave, the function of barbecue and light wave is to bake the surface from outside to inside, and the basic function is the same as that of oven, which often uses tin foil; Microwave has the characteristic of metal reflection, so the use of tin foil will produce sparks. When I barbecue in lg microwave oven at home, I usually wrap the easy-to-burn parts with tin foil to prevent them from burning.
