This is Ausfuhrung 134 decor. It is produced with base color glass with Titania glass decorating the design. 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. What differentiates the pieces is the earlier pieces look more Moser like with strong ground rim and sometimes a band of acid etching. These are clearly contemporaries of Tango glass because they Contain a black or blue detail color as much of the tango line does.
