What historical movements popularized cast iron in abstract sculptures?

The use of cast iron in abstract sculptures gained prominence through several key historical movements. The Industrial Revolution (18th–19th centuries) made cast iron widely available, encouraging artists to experiment with this durable, malleable material. Modernism in the early 20th century further embraced cast iron for its raw, industrial aesthetic, aligning with movements like Constructivism and Bauhaus. Post-WWII abstract expressionists utilized cast iron to create bold, textured works, while contemporary artists continue to explore its versatility in large-scale installations. These movements collectively transformed cast iron from an industrial commodity into a celebrated medium for artistic expression.
