Berlinois red wine glass

Height 15.5 cm. Unusual Berlinois glass with optical stripes in cuppa. We have never seen this before. The glass is mouth-blown with a sand nail underneath and from the end of the 19th century. It is in perfect condition. Berlinois was made at all the larger Danish glassworks, Holmegaard, Kastrup and Fyens Glasværk from the end of the 19th century up to the 1940s, where it was taken out of production. Today, it is impossible to tell the different glassworks' glass from each other. Item number: 10497
