Sculpture as states of matter: Christine Corday's ingenious adaptations of natural processes This monograph covers the past 20 years of New York-based artist Christine Corday's (born 1970) practice. Corday combines her interests in the sciences and fine arts to paint, sculpt, draw and design. Her artistic approach consists of manipulation of matter into different states, producing massive sculptures that viewers are meant to experience through touch, leaving memories on the surface of her work. Her most recent work includes the “Sans Titre”/ITER project, which includes Corday’s sculptures within the world’s first star built on earth; the Protoist Series, a group of metal alloy sculptures designed to change and rust with human interaction (the first was displayed under the High Line in New York City and subject of a solo exhibition at Los Angeles County Museum of Art); the black iron oxide color selected to cover the National September 11 Memorial; abstract charcoal drawings; and abstract synthetic polymer and pigment paintings. The term “protoist,” coined by the artist, is meant to describe forms in and out of a solid state.
