Topic: Chalcedony/Calcedonian glass flask

[glassgull]

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?
Thanks, Greg

Can we actually just see the bottle (can't see the shape though your hand) and a base picture please. Many companies worldwide made this sort of glass. Where are you; that might help.

These are a few more photos that I have downloaded on my computer.
I don't have a photo of the base as of now but I will try to take a few base shots.
I can tell you that the base has a solid glass pontil. As for where I live, that is in
Pennsylvania (USA). Thanks, Greg

Its very much like a big version of the tiny Venetian chatelaine perfume bottles of circa 1880 i have seen one that shape and colour but no more than a couple of inches , even the finish of the top  is the same .
