However, in practice, the temperatures maintained in the kiln are much higher (around 1350 deg C). The correct temperature in the kiln depends on the limestone size as well as type of kiln and type of fuel used. The kiln operator normally experiments to determine the exact temperature for the particular size and quality of limestone being used.
