In nature, Pennsylvania limestone has a rough, craggy exterior. But when it is cut open and dressed, it has an even veneer and crisp edges. In Inside Out, Buky Schwartz reversed our expectations about limestone's inside and outside. He sliced a quarried stone into four sections, and worked each interior until it was smooth. Schwartz then arranged the quarters "inside out," inviting us to walk into the sculpture to explore the raw outer surface of his natural material.
