Shannon,
i visited the other forum.
You can ask the people at Theresienthal, but they are not very familiar with the production of their glassworks around 1900 . Sometimes they ask me to tell them something about their former times.
Their collection of old samples and catalogues was around 1970 separated by the former owner of Theresienthal, Max Gangkofner, and put into a museum at the same location. This glassmuseum is a wonderful place to visit, but it doesn`t belong to the glassworks since in the early 1980ties Max Gangkofner sold the glassworks but kept the museum. For more than 25 years museum and glassworks went their own way and there wasn`t much communication between them. But since a couple of month it looks as if times are changing again and glassworks and museum will be able to work together :hiclp:!
Regards
Stephan
