Hi to all the good people here on this thread.
Although this thread is 3 years old, I feel i must add my two cents of thanks to you all, as this thread helped me to identify my recent purchase of a vase of this range. The funny thing is that while reading all the thread, I got such a strong feeling of 'this is about me, isn't it?'. All the range of questions and assumptions I made about my vase seemed to be described in here. Just as you, David, I bought with the 'I don't know what it is, but I know it is good' feeling. Just as you, I also suspected Karlovarske Sklo, and just like you, I was disappointed when reading the other thread in which it was identified it as modern Chribska. Just as you, I was delighted to know it is a karlovarske Sklo/Moser production, and to have the verification that my first hunch was correct.
Usually I am a silent reader in this forum, but I really think that this time I must step in and thank you all - David, Robert, Jhon and Anik, as well as glassobsessed.
