Ceramics Corridor: A Secret No More
Every industrial cluster owes its existence to a raw material. So it is with New York's Ceramics Corridor. Easily mined shale deposits, the birth of the New York State College of Ceramics and the glass-related wizardry of Corning Inc. have placed this region on its way as an advanced materials cluster.
