Abstract:
1. A handle for cooking utensils, to be joined to the edge of the utensil, said handle being made with a material having low heat conductivity and comprising: a) a plate of a material having heat conductivity, said plate having a part of one end in thermal contact with the edge of the utensil and the other end at a distance therefrom; and b) thermo-chromatic means applied in contact with different areas of the plate and having the ability to change color within predetermined ranges of temperature; the change in the temperature along the plate, caused by the change in the temperature of the bottom of the utensil, will in turn cause the change in color of the thermo-chromatic means and the display of information related to the temperature of the bottom of the utensil on different areas of the plate; wherein the thermo-chromatic means are crystals or mixture of crystals which have activating temperatures ranging from 20° C. to 100° C., show a specific color outside of the range of activating temperatures, and become transparent within that range, whereby areas of the plate increasingly distant from the body of the utensil reach the temperature at which the thermo-chromatic crystals are activated and become transparent, as the temperature of the bottom of the utensil increases, and vice versa as the temperature of the bottom of the utensil decreases.
