Polishing and burnishing are two processes used to make smooth and shiny surfaces. Polishing is the process of rubbing a surface with an abrasive material, such as a cloth or paper, to remove any imperfections and create a smooth finish. Burnishing is a similar process, but it involves using a harder material, such as a metal tool, to create a glossy shine. Both processes involve rubbing the surface in a circular motion until the desired result is achieved.
