No, you should not place the rotating glass plate from a microwave into a toaster oven. Microwave-safe glass plates are designed to withstand the unique conditions inside a microwave, such as rapid and uneven heating caused by microwave radiation.
Toaster ovens, on the other hand, use heating elements to cook food through convection, which involves hot air circulating around the food. Placing a microwave-safe glass plate in a toaster oven could cause it to shatter or crack due to the sudden temperature changes and direct contact with the heating elements.
If you need a rotating feature in your toaster oven, you should look for models that come with a built-in rotisserie or other specific features designed to handle rotation safely. Always refer to the manufacturer's instructions and guidelines when using any kitchen appliance to ensure safety and proper usage.
