Six microscopic enlargements of minerals, page, photomechanical print, Image 1 is calcite, 2 is hypersthene, 3 is anatase, 4 is nepheline, 5 is dacite, and 6 is granite., number: 'Tafel Greifswald, cliché maker: J. Grimm, Offenburg, c. 1880 - in or before 1885, Emil Cohen, J. Grimm, photographer, cliché maker, Baden-Württemberg, Mecklenburg-Vorpommern, Greifswald, paper, collotype, photoprint, height 233 mm x width 149 mm, minerals and metals, A vertical sheet with a light background contains six circular black-and-white close-up images arranged in two columns and three rows, each circle showing varied textured patterns. The top left circle shows a grid-like mosaic of intersecting straight lines forming irregular rectangular blocks. The top right circle displays layered striations and diagonal fractures crossing horizontal banding. The middle left circle contains a darker irregular fragment with rough granular texture and subtle linear markings along its surface. The middle right circle presents a circular field with a central rectangular area filled with a tight crosshatched pattern surrounded by mottled irregular regions. The bottom left circle shows a roughly hexagonal textured patch with crisscrossing lines embedded in a speckled background and a few angular fragments nearby. The bottom right circle features a layered, plank-like structure with horizontal bands and irregular dark splotches around its edges.
