In its simplest conception, a Fineness of Grind Gage may be considered essentially a continuous variable screen. It can be readily seen that if a material such as fine silica were distributed uniformly in a single particle thickness in the gage path, these particles would protrude above the sides of the path starting at whatever point that their physical size exceeded the depth of the path.
