Glass artist Preston Singletary: Shattering expectations

Preston Singletary, a member of the Tlingit tribe of Alaska and the Pacific Northwest, uses a very untraditional medium when fashioning indigenous art: glass. He talks with correspondent Lilia Luciano about his traveling exhibition, “Raven and the Box of Daylight” (now at the Museum of the American Indian in Washington, D.C.), which tells a Native American folktale about the origins of the world entirely through glass.
