What are the challenges of preserving the original intent of cast iron abstract sculptures over centuries?

Preserving the original intent of cast iron abstract sculptures over centuries presents numerous challenges. Environmental factors like humidity, temperature fluctuations, and pollution can cause rust and structural degradation, altering the sculpture's appearance and meaning. Additionally, the artist's initial vision may be lost as interpretations evolve over time. Restoration efforts must balance historical accuracy with modern techniques, often risking over-cleaning or inappropriate repairs. Furthermore, the lack of documentation about the artist's intent complicates conservation. These challenges highlight the delicate balance between maintaining physical integrity and honoring the artwork's conceptual essence.
