A method and preliminary apparatus are proposed for the rapid and accurate determination of inorganic fiber densities. Initial experiments with small glass chips gave a maximum deviation from the density of bulk glass of less than 0.1 with an average deviation of 0.02 for 10 determinations. In essence, the method proposed utilizes immersion of single fibers of short lengths in liquids comprised of a mixture of individual liquids of greater and lesser densities than the fibers. An average of the easily measured liquid densities in which the fiber slowly rises and falls is proposed as the fiber density. Improvements in the technique and apparatus to determine fiber density are presented and further refinements are suggested. Adequately reproducible results were collected for various measurements of glass and quartz fibers. Author
