Achieving a smooth, polished finish on metal sculptures requires a combination of mechanical and chemical techniques. Grinding is the first step, using progressively finer abrasives to remove imperfections. Sanding follows, with wet or dry methods to refine the surface. For a mirror-like shine, buffing with specialized wheels and compounds is essential. Chemical treatments like patinas can add depth and luster, while electroplating offers durable coatings. Finally, protective sealants preserve the finish, ensuring longevity. Each method demands precision to enhance the sculpture's aesthetic appeal.
