I was wondering if anyone is familiar with Chalcedony/Calcedonian glass?
I have an old free blown glass flask that I have included pictures of that
was made with Chalcedony/Calcedonian glass. There is a old collection sticker
on the neck. I am aware that the Venetian/Murano glass blowers worked with
Calcedonian glass in early times and still do today. I have heard that there
was a revival of Calcedonian glass manufacture in Germany mid 19th century.
Because of the form of the flask, I was leaning on German manufacture mid 19th century.
Has any one seen anything like this flask and possible know of its origin?
