In the ceramics industry, the combined effect of temperature and time is called heatwork. It is however not precise and is not a valid scientific concpet

To an extent pyrometric devicess can be used to gauge heat work as they deform at particular heatwork values, thus producing temperature equivalents, not actual temperature values. With tolerances firing can be undertaken at lower temperatures for a longer period to achieve comparable resulst to higher temperatures for a longer period. When the amount of heatwork for two firings is the same, the pieces may look identical although there may still be differences not visible to the eye such as mechanical strength and the microstructure.
