Thank you Craig!
Yes, this CMS Krasno range is quite unique. The pulegoso pieces are more commonly seen -- like the lamps I posted in the other thread.
The black-and-white catalogue in the link I posted above shows many pieces in this style with bubbles or multicolour spatter plus flowers suspended in thick clear glass.
I attach a pic of a studio glass vase by Jindra Beranek, sort of a remake of one of these vases (his father Emanuel Beranek made in the 1940s for CMS Krasno).
