Abstract
A glue gun dispensing nozzle indicator changes color when a heater element exceeds a transition temperature. In one embodiment, the temperature indicator changes from a blue color to a red color to indicate that the temperature is sufficient so that the glue gun may dispense molten glue. Temperature dependent color pigments are applied as coatings to the indicator.
