PITTSBURGH PLATE GLASS COMPANY.  In 1883, Captain John B. Ford and John Pitcairn established the Pittsburgh Plate Glass Company (PPG). They opened their business in Creighton, Pennsylvania, along the Allegheny River about 20 miles north of Pittsburgh. 

PPG became the first commercially successful producer in the United States of high-quality, thick flat glass using the plate process. The company was also the world's first plate glass plant to fuel melting furnaces with locally-produced natural gas. This innovation quickly stimulated widespread use of clean-burning gas as an industrial fuel.
