Polishing

 Products need to be polished in order to give them a high gloss surface. Polishing can be used as a preliminary and as a finishing treatment. Any metal can be polished, but this treatment is mostly used on copper, silver meshing, aluminium and stainless steel.

Every remaining material structure must be removed and the surface must be as smooth as glass, as any defect in the material will be emphasized further once the decorative layer is applied.
