American, Scandinavian, and Italian colored glass took on exuberant forms after World War II. Most manufacturers never intended for these decanters to be filled with wine or spirits; they were marketed as decorative items. Indeed, some were produced on such a grand scale -- up to four feet tall -- that they would require several gallons of liquid (and be nearly impossible to pour from). The trick is finding them with their original stoppers, which were often lost over time.
Top right, Italian examples, such as the tallest decanter, center, are displayed alongside American ones, such as the red Blenko piece with teardrop stopper, right, and one by Rainbow, second from left. Also shown is a rare scallop shell, right, blown from opalescent glass.
