Thixotropy is a reversible decrease of viscosity caused by sustained deformation, followed by recovery while the material rests. It requires an evolving microstructural state and therefore depends on shear history.
Thixotropy is a property of certain gels and fluids that are non-Newtonian, meaning their viscosity changes under stress or over time. Specifically, thixotropic substances become less viscous when subjected to shear stress (like stirring or shaking) and will gradually return to a more viscous state when allowed to rest.
