Almost as important as making the glass is transporting it safely to the customer. In times when wheels were not pneumatic, the roads rough, and neither polystyrene nor foam materials were available, this was not a trivial task. Packaging required experience and care, and then it was typically ripped off and discarded as soon as the wares reached their destination. Very rarely has pre-modern glass packaging survived, but when it has, it offers an astonishing insight into this skill. These shot glasses were made in northern Germany in the late 18th or early 19th century.
