Type of Chemicals Used in Bronze Restoration

Hi, I was wondering what are the different types of chemicals you use for bronze restoration? I recently saw your video on a professional bronze statue restoration project, with the statue Anne. Also, how long did a project such as that take? Would the time change based on the size of the piece being restored?

One of the chemicals used for bronze restoration would be potassium sulfide. As a cold application, we may also use M20, depending on how the bronze reacts to the patina chemical. Regarding the bronze statue restoration, a project such as Anne, would take about 1 week or longer depending on the surface condition. The time would change based on the size of the piece being restored as there would be more surface area to treat as well as accessing the bronze artwork to carry out the restoration.
