Abstract[EN] In the last years the use of rheometric techniques like control stress and oscillation measurements has become popular. In this work the basic concepts of suspensions rheology are revised and the recent rheometric techniques for their complete characterisation are analysed. From a previously optimised slip of sanitary porcelain with a solid loading of 50 vol%, different kinds of rheological tests and the most frequent regression models are described and analysed, as well as the limitations and the possible ways to plot a rheogram in order to reach a maximum information. The differences among rheological parameters obtained in different ways are discussed, focusing the determination of the yield stress which is the key to distinguish a plastic behaviour from a pseudoplastic one.
