Liberty Glass Co. of Sapulpa, Oklahoma, grew from a split in an earlier firm (the Bartlett-Collins Glass Co.) and became one of the largest and most successful milk bottle and soda bottle producers west of the Mississippi River. Although George F. Collins operated a second plant at Poteau, Oklahoma, it apparently only manufactured door knobs and other functional glass. Liberty purchased a glass house at Santa Ana, Texas, but apparently closed the facility immediately. Although the Sapulpa plant only produced milk bottles initially, it introduced soda bottles in 1934 or 1935, and sodas eventually became the firm’s flagship product. Liberty became part of the American National Can Co. in 1994 but retained its identity until it was absorbed by Ball-Foster in 1996.
