Abstract
Thermally responsive materials are provided having improved resolidification (recrystallization) characteristics. These thermally responsive materials are useful as temperature indicating compositions by undergoing change of state as precise and predetermined temperatures. Marked improvement in the rate of recrystallization of these thermally responsive substances is obtained by the addition thereto of so-called "nucleating agents" preferably supported on suitable support materials.
