From 1880 to 1930, glass manufacturing boomed along with the City of Cumberland.  Warren Glass Works Company, founded 1880, was one of the first to be established. Around 1920, well over 1,000 people were employed in the glass factories and decorating shops.
The end came with the onset of the Great Depression combined with the destruction of seven factories by fire.
The museum has several exhibit rooms of beautiful glassware and tools used in the old days of glass making made in Cumberland from the early 1900’s until the early 60’s.
The museum display features the Maryland, Potomac, and Utility Glass Companies.
