Describes the drying behaviour of clay-based and non-clay ceramics in terms of the external conditions influencing the rate of evaporation, and the internal mechanism with reference to moisture movement and shrinkage. The work mainly considers the practical aspects relating to problems and faults which arise during the drying of a preshaped article, although a theoretical treatment of the drying processes is provided for those requiring a deeper knowledge of this important subject.
Of interest to ceramics technologists, ceramics students and apprentices.
