For much of the 20th century the Owens automatic bottle-blowing machines were used to produce glass containers around the world. This machine and others revolutionized glass production and led to the end of hand production of commercial glass containers. Bottles produced on the Owens machines have distinct suction scars on their bases that make them easy to identify. Because of the way the rights to the Owens machines were licensed, these licenses have a great potential to establish the dates when the production of major categories of glass containers on the Owens bottle-blowing machine began. The first lease for the use of the Owens machine was issued in 1904, followed by a number of leases issued in 1905 and a few subsequent years. Thus 1905 is a good terminus post quem for suction-scarred glass containers. The last Owens bottle-blowing machine went out of production in 1982.
