WebOptical properties are a striking expression of the anisotropic internal structure of minerals. The best way to convince yourself that this is true is to examine a thin section of a rock (a 20–30 μm thick slice, see Chapter 10) in a petrographic microscope with polarized light and compare the effects with those from a plain glass slide.
