This is Ausführung 216 or drip application pieces. They are loetz from 1914-1938 in many tango colors. These vases also come in iridescent, crystal, transparent, and (rarely) satin flashed.
How I suppose they were made: A base color was created and blown into a balloon shape. The contrasting colored rim was hand applied to the neck of the piece then piece was transfered from the top to the bottom (cut just above the application). The shape is spun in a mold and the rim was worked or flared. The last step is to apply hot drips of glass to the shape witch sometimes looks perfectly symmetrical and sometimes not; it is flaming hot glass after all... .
