How does the porosity of cast iron influence the application of protective sealants on figurative sculptures?
The porosity of cast iron plays a critical role in determining the effectiveness of protective sealants applied to figurative sculptures. Due to its inherently porous nature, cast iron can absorb moisture and pollutants, leading to corrosion and degradation over time. Protective sealants must penetrate these microscopic pores to form a durable barrier, preventing environmental damage. However, excessive porosity may require multiple sealant layers or specialized formulations to ensure complete coverage. Understanding this relationship helps conservators select the right sealant and application technique, preserving the sculpture's structural integrity and visual appeal for years to come.
