Abstract
A method for monitoring frozen products and an indicator for temperature monitoring of the frozen products using one or several liquids with various melting temperatures; the liquids are encapsuled in cavities of an indicator and are frozen in certain geometric patterns. During the melting process these liquids lose their frozen shape. The cavities are at least partially elastic-deformable, and the liquid is forced into certain geometric patterns by means of mechanic deformation of the walls. The deformation of the walls is accomplished by application of a stamp which has been cooled.
