The results of experimental determination of a change 
in time of the intensity of moisture evaporation from the surface 
of a ceramic mass for soft-mud moulding in the initial period and 
in a portion of the first period of radiant drying are presented. 
Comparison between the theoretical solution obtained for the Fourier 
equation with the corresponding boundary conditions and experimental 
results has been made, which showed an agreement sufficient for practical 
purposes. Nomograms convenient for practical applications are presented.
