Czech glass - Zipper #1

In efforts to separate the zipper patterns into separate groups here is the next post- Satin Zippers. The colors are marbled through the piece with a vertical tooling that gives pieces a wild Zig-zag look. This type only comes on satin finished glass and the shapes seem unique. They are also distinct by because the pieces use a crystal and not an opaque base color- giving a beautiful effect inside and out.

The signatures are silver or bronze (as seen in the last picture); I call these the "smile" signature. The smile signature can also be found on some Kralik decors but this attribution is very tentative because the decors are not definitively Kralik. I would categorize these zippers as unknown until more shape matches are made.
