These glasses, primarily produced in England from approximately 1730 to the 1760s, were a popular drinking vessel, often replacing heavier lead glasses.
These vessels were often made of waldglas, or forest glass and dated to the late medieval and early renaissance period, most being found in Germanic areas, and the Low Countries.
Made for storing spirits, especially brandy, these bottles were made almost exclusively in Germany from the beginning of the 14th century all the way into the 17th century.
