Quote from flying free "Looks gorgeous but many vases were made as display pieces in themselves, not just to be used for flowers". I really cant comment on other glassmakers, but in Monart case, vases were made and sold for the use of flowers ect and not just for display. The first photo is from the British Industries Fair at Olympia in London circa 1930s the second photo is from J Moncrieff advertisement materail circa 1920s.
