* Weight and Solidity: Iron's weight and solidity allows Gormley to create imposing and grounded sculptures, often referencing the human body.
* Durability: Iron is a durable material, capable of weathering the elements and withstanding the test of time. This is crucial for sculptures intended for outdoor installation.
* Surface Texture: The textured surface of cast iron adds another layer of complexity to Gormley's work, reflecting light and shadow in interesting ways.
However, Gormley has also worked with other materials, including:
* Clay: He uses clay in his early works, as well as in more recent projects.
* Steel: Gormley has used steel in several sculptures, notably his iconic "Angel of the North."
* Lead: He has also worked with lead, especially for his smaller, more intimate pieces.
* Concrete: Gormley sometimes employs concrete for its raw and industrial qualities.
Ultimately, Antony Gormley's material choice is driven by his artistic vision and the specific demands of each project. While cast iron is his signature material, his willingness to experiment with other materials demonstrates his versatility as an artist.
