The Andreasen pipette method of determining grain sizes by sedimentation is a refinement of the ordinary pipette method. The apparatus was selected for the determination of grain size in a general study of clay casting slips after consideration of other methods. It permits precise results but requires more time and precision than some other methods. Graphs are presented for comparison of typical American kaolins and ball clays and English china clays and ball clays.
