Stress corrosion cracking (SCC) is a significant threat to bronze sculptures, often caused by environmental factors and mechanical stress. To preserve these artworks, several effective prevention methods can be employed.

1. Environmental Control: Limit exposure to corrosive environments, such as high humidity or polluted air. Indoor display or protective enclosures can significantly reduce SCC risks.

2. Protective Coatings: Apply wax or lacquer coatings to create a barrier against moisture and pollutants. Regular reapplication ensures ongoing protection.

3. Material Selection: Use bronze alloys with higher resistance to SCC, such as silicon bronze or aluminum bronze, which offer better durability in harsh conditions.

4. Stress Reduction: Minimize mechanical stress during fabrication and installation. Proper design and support structures can prevent stress concentrations that lead to cracking.

5. Regular Maintenance: Inspect sculptures frequently for early signs of corrosion. Prompt cleaning and treatment of affected areas can halt further damage.

By combining these strategies, bronze sculptures can be safeguarded against stress corrosion cracking, preserving their beauty and structural integrity for generations.
