thixotropy

The property of certain gels of becoming less viscous when shaken or subjected to shearing forces and returning to the original viscosity upon standing ( e.g., synovial fluid, ferrous hydroxide gel); a characteristic of a system exhibiting a decrease in viscosity with an increase in the rate of shear, usually a function of time. SYN: reclotting phenomenon. [G. thixis, a touching, + trope, turning]
