A process and apparatus are described for measuring the flow characteristics of a non-powdered material, e.g., a flushed pigment, and correlating them with actual production practice. The non-powdered material is placed into a cylinder having an orifice at its base, a piston with a known weight is placed on top of the material in the cylinder and after the orifice at the bottom of the cylinder is opened the distance traveled by the piston in a given time is measured and compared to the distance the piston travels with a known standard material.
