This discovery is the beginning of scientific metallography. Ceramography can be thought of as the metallography of ceramics. Bakelite is also used in the mounting of metal samples in metallography. A metallography or lapidary saw equipped with a low-density diamond blade is usually suitable. In 1916, he published "The Metallography of Steel and Cast Iron". There are four BAS research institutes&colon; Oceanology, Fisheries, Aero and Hydrodynamics, Metallography. Struers A/S of Copenhagen introduced the electrolytic polisher to metallography in 1943. In metallography, an alloy of interest is ground flat and polished to a mirror finish. These "nature prints" turned "metallography" into lithography. Before this, metallography was the primary method used for studying metals. Metallography is the study of the physical structure and components of metals, by using microscopy.
