Three Rivers Heritage Trail
In 1797, James O'Hara and Isaac Craig opened the first Pittsburgh glass manufactory on the South Side to serve a profitable market in the Ohio River Valley. By the 1870s the city had 46 glassworks and employed nearly 6000 people, third only to the iron and steel industry in productivity and employment.
Glass in the expanding new nation was needed for windows, mirrors, containers, flasks, lanterns, and bottles and jars for medicine, spirits, table ware, and countless other uses. The essential materials for glass manufacturing—fuel, silica, and potash—were plentiful in Pittsburgh, as was the skill of laborers and business enterprise.
The South Side was the home of many successful glass factories, including companies owned by Ihmsen, McKee, and Evans. PPG Industries, a leading global manufacturer of glass, began here in 1883. Pittsburgh glass was famous for its variety, ranging
