ABSTRACT:
A gauge for determining the fineness of particles dispersed in a liquid comprises a block (1) having a reference surface (8) in which are formed a series of flats (2) at different depths below the surface (8). In use of the gauge the liquid is spread over the surface (8) by a spreader blade resting on and drawn across the surface (8). The fineness of the particles in the liquid is interpreted from the manner in which the liquid has covered the flats (2) under the action of the spreader blade.
