How are repairs and restorations made to the Charging Bull statue?

Detailed answer

Repairs and restorations to the Charging Bull statue are made using traditional bronze working techniques, including welding, soldering, and casting, which are performed by skilled artisans and conservators who specialize in bronze restoration. When repairs are needed, the conservators will typically use a combination of visual inspection and non-invasive testing methods, such as X-ray fluorescence and ultrasonic testing, to assess the extent of the damage and determine the best course of treatment. The repairs are then made using materials and techniques that match the original construction of the statue as closely as possible, in order to preserve its historical and artistic integrity.
