An irreversible label or indicator of whether a surface or object has received microwave exposure and to delineate microwave heating or oven heating. Because microwave cooking has become an ubiquitous method for food preparation, and that energy and power in a microwave oven can vary from one unit to another, and within the spatial volume of the appliance, it is desirable to have a dynamic indicator that can provide an effective indicator of microwave exposure under such conditions.
