The images on these laminated glass panels in Concourse C originate from cyanotypes. This early photographic process uses UV-reactive chemicals exposed to sunlight.

To create the images, the artist collected stones, including some from the nearby Montour Trail, a former railroad line once used to transport coal to Pittsburgh’s steel mills. She placed them on paper coated with light-sensitive cyanotype chemicals. Where the paper was exposed to sunlight, the paper turned a deep blue; where the stones blocked the light, they left behind white silhouettes. These prints were in some cases, used as the surface for crayon rubbings of the ground, then scanned, and digitally enlarged. Each glass panel transforms small, ordinary stones into monumental forms that recall icebergs, islands, or planets. The deep blue tone conveys a moment of stillness and the subtle movement of light over time.
