Repairing a bronze sculpture with a bent element requires careful handling to avoid further damage. Here are the most effective methods:

1. Assess the Damage: Examine the sculpture to determine the extent of the bend and any potential stress points. Avoid forcing the metal, as bronze can become brittle.

2. Gentle Reshaping: For minor bends, use padded clamps or soft mallets to slowly coax the metal back into shape. Work gradually to prevent cracking.

3. Heat Application: For stubborn bends, apply controlled heat using a heat gun or torch to soften the bronze. This makes reshaping easier but requires caution to avoid overheating.

4. Professional Restoration: For valuable or complex sculptures, consult a professional conservator. They may use specialized tools like hydraulic presses or annealing techniques.

5. Post-Repair Care: After reshaping, clean the area and apply a protective wax or patina to match the original finish.

Always prioritize preservation over aggressive repairs to maintain the sculpture’s integrity.
