I have just joined the forum today so would like to say hello.
I have this piece of glass that I found at a stall in South West France but don't know anything about it. It has some writing engraved on one end but I'm not at all sure what it says. Maybe it's French. I'd like to know if anyone has an idea of where it may come from. It is quite solid when you tap it with your finger nails (it is actually hollow) and measures 7" x 4" (18 x 10cm) approximately. Weight 17.7oz (500gm).
Here are the images. I have tried to photograph the writing on the end but its not written on a flat bit of glass and reflections keep showing up. I'm sure a native speaker can read it though. I can read normal French but this may not be French.
The last two images look a bit strange because I wrapped a piece of black plastic and cloth round the main section to block out the light.
I've now added two more pictures. One from each end.





I can't see any mold marks anywhere but then maybe it was blown.
