fineness factor
A measure of the average particle size of clay and ceramic material, computed by summing the products of the reciprocal of the size-grade midpoints and the weight percentage of material in each class (expressed as a decimal part of the total frequency). The measure is based on the assumption that the surface areas of two powders are inversely proportional to their average particle sizes.
