This is Ausfuhrung 134 decor. It is produced using a tango base color layered with Titania glass. At some point the glass is crackled (by water most likely) reblown to expand the cracks in the titania then rolled in crystal casing glass. The design dates from 1920's but earlier decors with a strong similarity exist. The earlier pieces are have Moser-like cameo work with titania. These are clearly contemporaries of Tango glass because they Contain a black or blue detail color as much of the tango line does.
