The function of the microwave dish is to hold and rotate the food during cooking to ensure that the food is being heated evenly throughout. The microwave tray or microwave plate is usually made of toughened glass, not designed to be used in a conventional oven unless by design. The microwave turntable sits on the microwave roller ring and is driven by the turntable coupling.
