They are in the broadest sense of consumer goods when on beverage bottles or jars, and commodities, when one thinks of Drinking glasses or glass lamps.
The vast majority of hollow glass is made of soda lime glass. Exceptions are crystal glass and lead crystal and a variety of glasses for special purposes.
