	Determine percent irregularly shaped particles according to ASTM D1155.		Determine percent irregularly shaped particles according to ASTM D1155.

	Determine refractive index by comparing the test specimen with oils of known refractive index. Use a set of oils in the proper index range, graduated in steps of 0.01, for this comparison. Make the comparison by placing a few beads in the cavity of a hanging drop microscope slide, having a cavity of 1.7 mm deep. Select an oil of approximately the expected refractive index and an amount sufficient to immerse the beads in the cavity. Place the slide on the stage of a microscope having a magnification of approximately 150 power and illuminate from beneath with a white light source. A band of light, known as the Becke line, is visible surrounding each bead. This Becke line moves toward the medium of higher refractive index if the focus is raised, and toward the medium of lower index if the focus is lowered. By making slides using oils of varying refractive indices, and gradually narrowing the ranges, above or below the one originally used as becomes necessary, a point will be reached where the beads become invisible or have only a thin faint yellow Becke line surrounding them. When this occurs, the beads have the same refractive index as the oil, and this is the value to be reported for the beads.
