These are temperature sensitive chemicals shaped in the form of sticks. These are not temperature measuring but temperature Indicating crayons. You have to interpret temperature by observing the physical change taking place form solid to liquid. A surface is heated & you start marking (or rather touching) at intervals.for example you have a stick of 150oc with you.as soon as surface attains 150oc you will get liquid droplets in place of dry chalky mark.
