  skos:definition "1. A metallographic polishing process (MatPortal, BWMD Domain Ontology). 2. Polishing is the process of creating a smooth and shiny surface by rubbing it or by applying a chemical treatment, leaving a clean surface with a significant specular reflection (still limited by the index of refraction of the material according to the Fresnel equations). (Wikipedia). 3. Polishing goes beyond simply enhancing appearance—although that is often a key reason for its use. Polishing is all about eliminating imperfections that arise during manufacturing, ensuring that the final product is not only visually appealing but also functionally sound.
