Can Non-Microwave Safe Plates Cause Explosions in a Microwave Oven?

In summary, plates that are not marked "microwave safe" may crack in a microwave oven, but only if they have a significant moisture content. However, there have been no issues with nuking plates made of china, Corelware, Tupperware, or even old cracked melmac plates. The main concern is the release of toxic fumes or fluids, and plates with metallic patterns should be avoided. One way to test if a plate is safe for microwave use is to put it in the microwave empty for 10 seconds - if it feels warm, it should not be used.

Would plates that are not marked "microwave safe" explode in a microwave oven or crack slowly?

Some might crack, but I suspect that there would have to be a significant moisture content in the material. I routinely nuke stuff on china, Corelware, Tupperware, and even some 45 year-old melmac plates that are already cracked half to death. There's never been a problem with any of them. There is, however, the possibility of toxic fumes and/or fluids being released.

They could also just burn your food or damage the microwave.

Test any plate by putting it empty in the MW on high for 10 seconds.
If it feels warm, don't use it.

Good idea. Also, don't use one with a pattern... particularly if it looks metallic.
 

1. How do microwave ovens work?

Microwave ovens use electromagnetic radiation to heat food. This radiation causes water molecules in the food to vibrate, which produces heat and cooks the food.

2. Can you put metal plates in a microwave?

No, metal plates should not be put in a microwave. The microwaves will bounce off the metal, potentially causing sparks and fire. It is safe to use microwave-safe dishes made of glass, ceramic, or plastic.

3. Why do some plates get hot in the microwave while others stay cool?

The material of the plate plays a significant role in how it responds to microwaves. Materials like glass and ceramic are transparent to microwaves, while metals reflect them. This is why metal plates get hot and can cause damage, while other materials do not.

4. Can microwave-safe plates get too hot?

Yes, microwave-safe plates can get too hot if they are left in the microwave for too long. This can happen if the food is cooked for an extended period or if the plate is empty. Always use caution when removing dishes from the microwave and allow them to cool down before handling.

5. How do I know if a plate is microwave-safe?

Microwave-safe dishes will have a label or symbol indicating that they are safe to use in the microwave. You can also check the material of the plate - glass, ceramic, and most plastics are safe for use in the microwave. It is best to avoid using metal plates or plates with metallic accents in the microwave.
