Restoring antique bronze sculptures requires a delicate balance of artistry and scientific precision. Experts begin by thoroughly examining the sculpture to assess the extent of damage, including cracks, missing fragments, or corrosion. For minor cracks, they may use specialized adhesives like epoxy resins tinted to match the patina. Larger fractures often require brazing or welding with compatible bronze alloys, followed by meticulous filing and smoothing.

Missing sections are recreated using historical references or 3D scanning technology, then cast in bronze using traditional lost-wax methods. The new piece is carefully aged to blend with the original patina through controlled chemical treatments. Conservators prioritize reversible methods and document each step to preserve the artwork's integrity for future generations.

The final stage involves stabilizing the surface with protective coatings that mimic the original oxidation layers while preventing further deterioration. This painstaking process ensures these cultural treasures maintain their historical authenticity while regaining structural stability.
