I was hoping someone could have some information regarding this bottle my parents found during some renovations in a house in Charly, France (just outside of Lyon). It was found between a double stone wall of a building that dates to the late 1400's. The bottle is 22cm in length and about 4 cm wide at the base. The glass itself is fairly thin (compared to modern bottles) and has a very fragile feel to it. If anyone has any information as to what this bottle is, what it may have been used for, how common they are, etc... I would greatly appreaciate it if you would share your knowledge. My best guess, based on the shape, is that it may have been used for olive oil. But then again, I have no basis in my guess.
