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. 000135818 540__ $$9info:eu-repo/semantics/openAccess$$aby-nc-nd$$uhttp://creativecommons.org/licenses/by-nc-nd/3.0/es/ 000135818 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000135818 700__ $$aBerges, José-María 000135818 700__ $$0(orcid)0000-0002-0048-3036$$aCiria, José Carlos$$uUniversidad de Zaragoza 000135818 700__ $$aMaser, Wolfgang K. 000135818 700__ $$0(orcid)0000-0002-8654-7386$$aBenito, Ana M. 000135818 700__ $$aDuboys, Jean-Marie 000135818 7102_ $$15007$$2075$$aUniversidad de Zaragoza$$bDpto.
