I love these 1940s hotworked pieces made at Českomoravské sklárny (CMS, former S. Reich & Co), sort of precedessors of early Skrdlovice.

No wonder, several Skrdovice designers had worked there...
Quite a complex piece with flowers suspended in bubbly glass. Diameter 24 cm.
Marked to the base with a deeply etched mark, "R" and "Krasno".
My bowl can also be seen in the CMS 1945/6 catalogue Jindrich kindly made available on his site:
>> LinkI found this very interesting article online
>> Link, with lots of information on CMS 1930s/40s production.
Three designers for this range of hotworked pieces with flowers are mentioned: Frantisek Zemek, Milena Veliskova and Ludvika Smrckova.
I guess I will not get closer than that...
