   This is followed by washing and then a stage of finer grits (120-220 then 400-600 mesh), before the (optional) use of a pre-polishing compound (1200 grit), a washing cycle with detergent to remove any grit on the stones. The final step is a polishing stage using powdered polish, (such as cerium oxide or tin oxide), water, and often small ...

   A #4 architectural finish is characterized by fine polishing grit lines that are uniform and directional in appearance. It is produced by polishing the metal with a 120–180 grit belt or wheel finish and then softened with an 80–120 grit greaseless compound or a medium non woven abrasive belt or pad. #4 Dairy or sanitary finish

   Their technique involves making blackware using a fine-grained clay body fired in a cow-dung fire. By 1918 they had perfected the technique producing black-on-black surface ornamentation, created by selectively burnishing and polishing specific areas of the pot. [8] The polishing gives the clay a silver-black lustrous light-reflecting quality.

8. Polishing - Wikipedia

   en.wikipedia.org/wiki/Polishing

   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). [1]
