Selected rocks and minerals are ground and polished to a thickness of 20 – 30 μm. The preparations are mounted with Canada balsam on slides of 45x30 mm. In order to identify forms, colours, refractions and fossil inclusions, the slides can be observed with any normal microscope in transmitting light.
