Polishing by rubbing is a process of making an object smooth and shiny by rubbing it with a cloth or other material. Burnishing is a type of polishing that involves rubbing the object with a hard, smooth surface to make it glossy and reflective. This method is often used on metal objects such as jewelry, coins, and sculptures. It can also be used on wood and other materials. Burnishing is a great way to bring out the natural beauty of an object and make it look more attractive.
