Simply because microwave radiations impart energy to atoms and molecules in the crystal structure. Materials which can withstand the induced extra energy are safe, others are not.

Materials, metal or non-metal, are electrically classified as being conductors (at one extreme) or non-conductors (at the other extreme) Metals are conductors. When metals are placed in an an electromagnetic (microwave) field, they build up "charge". When the charge becomes extreme, the air around the metal will "ionize",causing discharging sparks. These sparks can cause the microwave generating device (usually a magnetron) to destroy itself or shut down. I use the oven to heat my meals, not "for fun". If you destroy the (expensive) magnetron, you can bet that your daddy will give you plenty of "no fun" and you will be eating cold meals - standing up.
