Abstract: A transparent vacuum formed vessel 1 is filled with a liquid 3 at room temperature that will become a solid at freezing temperature and a low density float material 4. After freezing, the vessel is turned upside down so that upon thawing, the vivid colored float will move to the top of the vessel showing a thaw. The devise can be reused. The same concept can be used as a cooking aid by using a transparent sealed tubular 1 assembly inserted in the food with a solid cylinder 3 that will melt at some critical temperature allowing the low density float to rise to the top of the indicator visibly protruding from the food. More than one meltable cylinder, 3 & 8 and float, 4 & 5 may be used as a warning and ready indicator. Combinations of solid dense particulates and low density materials may also be used for color changing indicators. A permanent magnet attached to a float can be used to trigger an audible alarm, which can be incorporated in various cooking utensils to show cooking temperatures and times.

Abstract: Disclosed is a temperature indicating method and device. The device embodies a sealed tube containing a liquid and a float. The tube has markings on the exterior indicating temperature zones or, in the alternative, temperature gradients. The method disclosed includes inverting the tube such that the indicator drops to the bottom of the tube and freezing the device at the appropriate temperature level.
