Metallography involves the preparation and examination of specimens for their microscopic structure which determines their bulk physical properties. Despite its name, metallographic methods can be applied to ceramics, glasses, polymers and biological materials as well as metals. Preparation typically involves sectioning, mounting in various polymer systems, grinding and polishing to a mirror surface, chemical or electro etching of the surfaces, optical or electron microscopy, and micro or nano indentation hardness testing. Macro hardness testing is also carried out in the Metallographic lab.
