The Passgläser were octagonal or sometimes round green beakers which were 20 to 35 cm high and decorated with 2 to 4 rows of glass trails. The glasses often had optical ribbed decoration too. Passgläser were used in Northern Europe from the middle of the 16th to the end of the 17th century. They were produced in Germany and the Netherlands, and latest by the beginning of the 17th century also in Denmark, Sweden and Hiiumaa, Estonia. Although Passgläser were the most common beer glasses of their time, we know that in Finland also spirits were drunk from them. The Passglas was an ideal beaker for communal drinking, because with the help of the applied trails each drinker could easily see what was his share of the drink.
