Which finish is described as smooth and glossy, usually achieved through friction?

The polished finish is characterized by its smooth and glossy appearance, which is typically achieved through a process of friction. This method involves rubbing the surface with a fine abrasive material, which removes imperfections and creates a shiny surface. The high level of shine indicates that the surface has been treated to achieve maximum smoothness and reflectivity, making polished finishes particularly desirable for aesthetic appeal in a variety of products, including metalwork, furniture, and even some forms of textiles.

The other finishes mentioned, such as burnished, matte, and satin, have distinct characteristics that differentiate them from a polished finish. For instance, a burnished finish, while also smooth, often involves a slightly different technique that may incorporate the use of tools to create a more subtle sheen rather than a high gloss. The matte finish, on the other hand, is intentionally designed to be non-reflective and lacks the slick luster of a polished finish, often giving a more subdued and elegant look. Lastly, a satin finish falls between a matte and glossy finish, offering a soft sheen without the high reflectivity that characterizes a polished finish. Thus, the polished finish stands out for its unique glossy quality achieved through friction.
