Vessel comprising a thermochromic indicator coating

A vessel for frying, baking or cooking of food having at least a visible first material and a visible second material, wherein at least the first material reversibly changes color thermochromically when heated,

• wherein the color of one of the two materials serves as a reference color for the respective other material, wherein a color difference between the two materials changes visibly when the vessel is heated, wherein a color difference between the two materials in a first temperature range corresponding to a cold basic state of the vessel is high, and in a second temperature range corresponding to a desired temperature range in the heated state of the vessel is low such that the color difference between the two materials disappears, wherein a bottom of the vessel and an inner edge of the vessel comprise the two materials, wherein the bottom is the lowermost surface of the vessel adjacent the inner edge, and the inner edge of the vessel is an interior surface of the vessel configured for receiving food, wherein the first material covers the entire surface of the bottom of the vessel and the second material covers only a portion of the one material such that the color difference is visible simultaneously, wherein the second material is in a form of speckles disposed along the inner edge of the vessel and the bottom of the vessel.
