Abstract:
    A lid for article of cookware is covered over a considerable portion of its surface with a thermochromic ink or paint to form a first thermochromic indicator. This first thermochromic indicator undergoes a readily visible change in appearance to notify the cook that the underlying cookware vessel and/or the contents thereof have reached the desired temperature. A second thermochromic indicator on the lid is used to indicate that liquid in the pot is also boiling, or that a certain time has elapsed since the change in appearance of the first thermochromic indicator. The first thermochromic indicator preferably surrounds the second thermochromic indicator and is separated therefrom by a thermal insulator to create or extend the time lag between each indicator reaching their respective thermochromic transition temperatures.
