How does the use of cores in cast iron molding enable hollow figurative sculptures?

The use of cores in cast iron molding is essential for creating hollow figurative sculptures, allowing artists to achieve intricate designs while reducing material weight. Cores are pre-formed inserts made of sand or ceramic, placed inside the mold cavity before molten iron is poured. These cores define the hollow spaces within the sculpture, ensuring structural integrity while maintaining artistic detail.

Once the metal cools and solidifies, the core material is removed, leaving behind a lightweight yet durable hollow structure. This technique enables the production of complex, large-scale sculptures without excessive material costs or weight. Historically, cores have been used in metal casting for centuries, but modern advancements allow for even finer details and precision in figurative art.

By combining traditional craftsmanship with core technology, artists can push the boundaries of cast iron sculpture, creating lifelike and expressive works that would be impossible with solid casting methods.
