Bakalowits vase by Lötz documented twice

The origin of a collected object is probably of great importance for every collector. It is important to be able to use reliable sources. Thanks to the surviving patterns of the glass factory Johann Lötz Witwe in Klostermühle, we can today clearly attribute a great many glasses to the Lötz production. But there are other reliable sources, including contemporary magazines and books that reported on new developments in art and decorative techniques or reviewed exhibitions. One of these magazines in Germany was the "Deutsche Kunst und Dekoration". Rarely, but still, modern art glass was presented here.
In the March 1900 issue, there is an illustration of four vases made by Bakalowits Söhne in Vienna (Fig. 1). We know that they were made in Klostermühle by order of Bakalowits. They were exhibited in the k. k. Museum für Kunst und Industrie (imperial-royal Austrian Museum of Art and Industry) in Vienna, today's Museum für Angewandte Kunst (Museum of Applied Arts, MAK). We may safely assume that the glasses were illustrated in the magazine because of their exceptional quality and shapes.
The two vases in the center show the Phänomen Gre 7773, probably in the base color ruby. Thus, the rubin (ruby) PG 7773 vase shown here (picture 2 and 3) is documented twice, once with the pattern sheet 85/3723 by Lötz (picture 4) and by the publication in the monthly magazine "Deutsche Kunst und Dekoration" in 1900. The vase, like all glasses made exclusively for Bakalowits, is not signed.
