The progress of drying can be followed in various ways. The drying process can be seen very clearly in the volume changes. Since drying can proceed only at surfaces in contact with unsaturated air, it takes place most rapidly at places where the air is constantly renewed. In the storage location for articles standing freely, the drying takes place mainly from the top surfaces and from the sides to a lesser extent where as from the bottom it is almost nil or very low.
Until few years ago there was a general perception about ceramic articles drying prevailed that is for better drying with minimal losses the drying process should be an elongated and extended time consuming operation.
