Iron In most cases, Chung uses abandoned or disused materials in his works. In modern society, those materials are mostly industrial wastes such as railroad ties, asphalt concrete, pebbles, and iron reinforcing bars. Here, the artist uses iron reinforcing bars to create new form. There is the reiteration of the horizontal and the vertical in Chung Hyun’s works in addition to the repetitive rotation of the linear and the voluminous. Here, the artist uses iron reinforcing bars to create the vertical forms. Chung Hyun's recent vertical work contrasts to the horizontal forms in his earlier work with ascon, suggesting an increased interest with verticality. The vertical forms already appeared in the solo exhibition at the National Museum of Contemporary Art where the posts installed at the entrance of the museum predicted the future orientation of his works. His recent works express verticality using iron reinforcing bars, soaring high in the air existing on the borderline between sculpture and ‘non-sculpture.’ They barely exist as sculptural forms and non-forms. The great tension in his works attracts the entire space with an inescapable magnetic force.
