Discussion Overview

The discussion centers on the safety of using non-microwave safe plates in a microwave oven, exploring whether such plates can explode, crack, or cause other issues during use. The scope includes practical experiences, safety concerns, and potential risks associated with different types of materials.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant questions whether non-microwave safe plates could explode or crack when used in a microwave.
  • Another participant suggests that cracking may occur, particularly if the material has significant moisture content, sharing personal experiences with various types of plates without issues.
  • Some participants raise concerns about the potential for burning food or damaging the microwave itself.
  • A suggestion is made to test plates by microwaving them empty for a short duration to check for warmth as an indicator of safety.
  • There is a caution against using plates with patterns, especially those that appear metallic, due to potential risks.

Areas of Agreement / Disagreement

Participants express differing views on the safety of non-microwave safe plates, with some sharing personal experiences of safe usage while others highlight potential risks. The discussion remains unresolved regarding the overall safety and risks involved.

Contextual Notes

Limitations include varying definitions of "microwave safe," differences in plate materials, and the lack of consensus on the conditions under which plates may fail in a microwave.

Would plates that are not marked "microwave safe" explode in a microwave oven or crack slowly?
 
Science news on Phys.org
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.
