Bronze sculptures are prized for their beauty and historical significance, but oxidation can tarnish their appearance over time. To preserve these artworks during storage, follow these expert-recommended methods:

1. Control Humidity Levels: Maintain a stable environment with 40-50% relative humidity. Use silica gel packs or dehumidifiers to absorb excess moisture, which accelerates oxidation.

2. Apply Protective Coatings: Coat the sculpture with microcrystalline wax or lacquer to create a barrier against air and moisture. Reapply periodically for long-term protection.

3. Use Anti-Tarnish Strips: Place activated charcoal or anti-tarnish strips near the sculpture to absorb corrosive gases like sulfur dioxide.

4. Avoid Direct Handling: Wear cotton gloves when moving bronze sculptures to prevent oils and acids from your skin from causing oxidation.

5. Store in Acid-Free Materials: Wrap sculptures in acid-free tissue paper or polyethylene foam, and place them in sealed containers to minimize exposure to pollutants.

By implementing these techniques, you can significantly slow oxidation and keep your bronze sculptures in pristine condition for years to come.
