.... This allows the mount to pass smoothly over the subsequent polishing cloths and prevents the plowing aside of abrasives by a sharp edge. Failure to use a bevel slows polishing on long-nap cloths. Following grinding, the specimen is flat to the edges, and the pores are almost completely smeared ( Fig...

...-dark field) is used to bring out subsurface features such as microcracks. With dark-field illumination, the light path is blocked from the objective center and is directed to the specimen at an oblique angle. This eliminates the reflected image in favor of the image formed as light passes through the...
