Popcorn Breaking Glass Microwave Tray

Glass trays in GE microwaves are tempered glass and resistant to heat and shock. It is very unusual for one to break.

However, there have been some instances of stress points occurring in the glass due to extreme heat from the popcorn bag caused by continuous cooking of popcorn or if the popcorn is stale and does not pop. This can possibly cause cracking or breakage of the glass tray.

Some brands of microwave popcorn recommend placing a plate under the bag for proper popping. If this is the case, follow the packaging instructions.

Note: It is not recommended to use the microwave without the glass tray in place.
