Green ashtray: Technically Sklarny Inwald, 1946, pattern number 12478/165, designed by Rudolf Schrotter, but still produced at Rudolfova Hut', as late as 1986. Pattern name Roma. So Sklo Union.
Blue " Four Lens" vase: again Schrotter 1955, pattern number 914, Rosice. So Sklo Union.
Amber vase: Rosice @ 1962, so Sklo Union.
Last one. I think this differs from the vase in the link above, which does not have these lens??? if I remember correctly.
I have no definitive Sklo Union id for this, though it reminds me of something by VEB Ostglas. I'll see what else I can find. Definitely pressed decoration??
