The paper aims to investigate the mass gain in fired clay ceramics following reheating in order to gain a better understanding of the underlying kinetics of the rehydroxylation reaction using advanced gravimetric analysis. The effects of temperature on the kinetics of mass gain in fired clay ceramic following reheating to 500 ºC are investigated. Arrhenius plots are constructed at different temperatures and the activation energy of the chemical recombination reaction calculated. Following reheating at 500 ºC, fired clay ceramics gain mass due to the chemical recombination of atmospheric moisture and hence mass gain occurs in two distinct steps that both are linear with (time)1/4. Separating Step II data from Step I provides insight to the nature of the Step II reaction.
