Defective Brick, an art installation exhibited at Artists’ Space in New York City, was produced with the support of Claudia Gould, then director of Artists’ Space, and with a National Endowment of the Arts (NEA) Grant in 2000. For the exhibition, a free standing structure with 539 hydro cal bricks was fabricated, conceived as an art project, yet scaled up as an installation. The scale demanded resolution of tectonic and technical issues. Three material choices proved critical in this installation. First, white silicon was used as an adhesive instead of traditional mortar, providing a flexible bond between each brick. Second, aluminum tubing was used as structural reinforcement rather than steel R-bars, allowing a greater curvature ratio for the meandering walls. And third, Hydro- Cal was used as casting material creating a continuous monochromatic mass where shade and shadow played an important role. In the development of this exhibition, research into the nuances found in the work of Sol Lewitt, Robert Ryman, and Agnes Martin was conducted. Later collaboration with these artists proved crucial for the project at Dia:Beacon.
