Webshear rate the viscosity decreases as a result of the breakdown in structure. In the second part of the experiment, the shear rate decreases (as a result of the decreasing stress sweep). The viscosity then increases, but at a slower rate than it dropped ini-tially (see Figure 4). Thus, for one shear the curve will produce two different values ...
