Over time, the bronze had oxidized, and because of the applied patina, acrylic polymer and wax, it required a more intensive process than just a simple cleaning or polishing. Over four days, an artisan utilized a process using crushed walnut shells to gently strip the figure down to the bare bronze. After cleaning, various chemicals were applied and heated with a blowtorch to create a reaction and fuse with the bronze. The figure was coated in a polymer to protect the patina, then coated with a very thin layer of wax.
Happy creation day to the duo who started it all 92 years ago today — Mickey Mouse and Minnie Mouse!
