Brockwitz Glass Celery Vase - 1915 Catalogue- Curved Star or Zurich

I bought this in a charity shop this morning. I have found out it is Brockwitz Glass, and is shown in their 1915 Catalogue, though it may have been made before that. The pattern is known as Curved Star, or Zurich, and I have seen examples made in Carnival Glass. It looks like cut glass, but is pressed glass. I like the little sticky out bits at the bottom of the pattern (not a very technical term!).
