A method of operating a continuous ceramic kiln having a decarbonization zone characterized in that oxygen or oxygen enriched air is added to the decarbonization zone to maintain the average oxygen concentration in the decarbonization zone at or about a predetermined level. The predetermined level need only be adjusted for different throughputs and need not be adjusted for moderate changes in the amount of organic matter in the clay.
