Glass mark
A glass mark (also known as glass signature ) is the mark that a glassworks attaches to a glass container so that it can be identified as the manufacturer.
This glass tag is usually found at the bottom or bottom of every bottle and canning jar.
Use in Germany
The application of glass marks was introduced in Brandenburg in the first half of the 18th century . From 1733 the full name of every glassworks should be put on every bottle . From 1739 the year of manufacture also had to be supplemented in order to counter incorrectly used dimensions.
In Germany about 20 such signs are used. They usually contain one or more letters, often surrounded by a circle. For example, B stands for the glassworks in Budenheim , G for Gerresheimer Glas , H for the glassworks in Holzminden . These manufacturer marks are assigned by the Physikalisch-Technische Bundesanstalt .
In addition to the glass mark, there are other characters that indicate when and where the item was made, as well as information about the volume . The individual labels and their arrangement are specified in DIN 6121.
