Slips, the final industrial dispersions, are complex in their rheological behavior, featuring non-Newtonian flow and thixotropy. In this work, a resonance vibrating-rod viscometer (VRV) was utilized to evaluate the viscosity evolution over time, showing advantages over a classical rotational viscometer. Notably, while both viscometers were sensitive to small quantities of a deflocculant, the VRV effectively described the typical increase in the viscosity of clay dispersions at rest (thixotropy), the experimental data being properly fitted by a phenomenological model. As a relevant technical aspect, the superior suitability of the VRV for in-line process control was highlighted in the continuous monitoring of stirred clay dispersions and slip casting in plaster moulds. Additionally, a fitting model was developed to elucidate viscosity evolution during the casting process. In summary, this study underscores the versatility of the VRV as a control instrument in the sanitaryware industry. info:eu-repo/semantics/openAccess by-nc-nd https://creativecommons.org/licenses/by-nc-nd/4.0/deed.es 5.8 2024 MINERALOGY 1 / 31 = 0.032 2024 Q1 T1 CHEMISTRY, PHYSICAL 57 / 185 = 0.308 2024 Q2 T1 MATERIALS SCIENCE, MULTIDISCIPLINARY 129 / 461 = 0.28 2024 Q2 T1 1.077 2024 Geochemistry and Petrology 2024 Q1 Water Science and Technology 2024 Q1 Soil Science 2024 Q1 Geology 2024 Q1 10.3 2024 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Berges, José-María Ciria, José Carlos Universidad de Zaragoza (orcid)0000-0002-0048-3036 Maser, Wolfgang K.
