This document specifies a method for measurement of thixotropic behaviour of ceramic slurry with rotational viscometer. The slurry with high-solid loading, which is used in ceramic manufacturing, has a generally non-Newtonian property. This method is limited to measurement of thixotropic behaviour of high-solid loaded ceramic slurry with “coaxial double cylinder viscometer”, “cone and plate viscometer” and “a parallel plate viscometer” as rotational viscometers.
