Glasses were typically replicated when an individual ordered a drink from a replicator. They were also used in bars to serve drinks from bottles. (TNG: "The Neutral Zone", "In Theory"; DS9: "Dramatis Personae")

Glasses were also used to give toasts, especially at formal occasions. (Star Trek VI: The Undiscovered Country)
