A method has been designed which uses the capillary viscometer for determining the constitutive equation for ceramic pastes. The method allows the active forces or pressure at a mean flow velocity or volumetric rate of flow of the paste through the capillary to be measured reproducibly while maintaining the conditions following from the theoretical principle of the method. The results obtained by processing the experimental data are used to describe the flow curve and to derive the constitutive equation for the respective porcelain paste.
