Kristi,
the story is more difficult that you can find at official egermann.cz web site.
Old Friedrich Egermann came from Polaun (Polevsko) near Haida (Nový Bor) and the story is almost correct, he invented yellow glasing (1817-1818) and red glazing in 1832. His invention was quite soon stolen and reproduced in a lot of factories in Bohemia and abroad as well. In his work continued his sons Friedrich Egermann jun (1822-1897) who has founded his own workshop in Haida and Anton Ambroz Egermann, mentioned as glass painter. The what has happened with his workshop and ownership in period up to 1945 is not clearly described in my books, it is mentioned that in 1914 introduced Karl Pohl black glasing - teacher in Glass School in Haida. The combination of red glazing and engraving called "Egermann" had been used bz several glass rafinators in 30ties , named are companies C. Goldberg and J. Oertel but for them had worked rafinators-specialists at their home workshops from whole Haida region.
After WWII was glass indusrtry in Czechoslovakia nationalised and the national company Borocrystal n.p. (later Borské sklo n.p.) has been extabilished. The "Egermann" style rafinators F. Lichtenecker, R. Wenzel and Köning continued in their work in frame of Borocrystal and has teached next generation of specialists Josef Svoboda and Jaroslav Chlupáč. Chlupáč estabilished in 1953 glasing workshop in Borské sklo n.p.. In 60ties and 70ties was technology of red glasing improved and in 1967 installed new glasing furnaces. Never ending re-organisationing and re-naming mania of socialist industry was crowned in 1974 when several glass factories has been unified to concern Crystalex. The Exbor as a division 13 of Borské sklo n.p. and later Crystalex was founded in 1962 like the art glass atelier in frame of factory and later concern, not separated company. The company named "Egermann" did not exist at that time. You can find the "Egermann" type of glass and ment is always the red glased glass with engraved castle or deer or rather both.
After 1989, in 1991 and 1992 was from Crystalex concern divided several factories and Crystalex privatised. In this time had been first in history introduced company as former part of Crystalex named Egermann-Exbor (in two forms Ltd and AG), this company bancrupted and the Egerman s.r.o (Ltd) founded than. Crystalex bancrupted last month, the situation of Egermann s.r.o. is not clear now. Absolutely sure however is, that this young company uses the Efermann name like a marketing icon, the traditional fabrication was totaly changed by introducing nwe technology in 60ties.
In fact many good and rich engraved red pieces called "Egermann" came just from 60ties, the recent production should be recognised from relatively ligher red colour and less rich engraving.
