Rheometric data of a thixotropic bentonite suspension were used for the identification of selected rheological models of thixotropic flow behavior. Rheometric data, obtained for different deformation histories, were compared with theoretical predictions derived from the rheological model for the same deformation histories. At low shear rates, superanomalous behavior of the bentonite suspension has been observed. The capability of the rheological models to reproduce this unusual phenomenon is discussed. Torques necessary to agitate a thixotropic suspension by means of a small‐scale anchor agitator were calculated on the basis of the rheological equation and compared with torques obtained, for the same deformation histories, experimentally on the same agitator. Good agreement between theory and experiment has been found.
