Polishing

Polishing is a kind of processing method, which is in order to create a smooth surface by rubbing it or using a chemical action, leaving a surface with a significant secular reflection, but it is still limited by the index of refraction of the material according to the Fresnel equations. In some materials like metals, glasses, black or transparent stones. Polishing is also able to reduce diffuse reflection to minimal values. When an unpolished surface is magnified thousands of times, it usually looks like mountains and valleys. By repeated abrasion, those "mountains" are worn down until they are flat or just small "hills." The process of polishing with abrasives starts with coarse ones and graduates to fine ones. Polishing with very fine abrasive differs physically from coarser abrasion, in that material is removed on a molecular level, so that the rate is correlated to the boiling point rather than to the melting point of the material being polished.
