Chapter 2 - Viscosity of Fluids
... fluids require the development of a significant level of shear stress before flow will begin, as illustrated in Fig. 2.2. Once flow starts, there is an essentially linear slope to the curve indicating a constant apparent viscosity. Eg. Chocolate, mayonnaise, toothpaste ...

... Elasticity can be seen by a reduction, at least partial, of the deformation when the load applied on a body is released. From ambient temperature (or below) and up to relatively high temperatures (T < 1,000°C), ceramics are elastic materials par excellence: their behavior under load is most often li ...

When extreme care is taken, the transition can even happen with Re as high as 40000. On the other hand, Re = 2000 appears to be about the lowest value obtained at a rough ...
