Achieving a mirror-like polish on bronze surfaces is a meticulous process that requires patience, skill, and the right techniques. Sculptors begin by carefully sanding the bronze with progressively finer grits of sandpaper, starting from coarse (around 80-120 grit) and moving up to ultra-fine (1500-2000 grit or higher). This gradual refinement removes imperfections and creates an increasingly smooth surface.
After sanding, artists often use polishing compounds, such as tripoli or rouge, applied with soft cloth wheels or buffing machines. These compounds act as micro-abrasives, further refining the surface to a high shine. For hand polishing, sculptors may use felt pads or leather strops with specialized metal polishes.
The final step involves protective measures to maintain the shine. Some apply clear lacquers or wax coatings to prevent oxidation, while others rely on regular maintenance polishing. The key lies in consistent, even pressure and attention to detail throughout each stage, transforming raw bronze into a dazzling reflective surface.
