Approx. 350ml, 11.83 US fl.oz Rummers, also known as Rmers or Roemers & other variations, were large drinking-glasses studded with prunts to ensure a safe grip, popular mainly in the Rhineland & the Netherlands from the 15th through the 17th century. They lacked the flared bowl of the Berkemeyer & had much thinner walls. The hollow base was built up by coiling strands of molten glass around a conical core. Rmers were quite distinct from the Berkemeyers, but both types evolved from the German cabbage stalk glasses which were cylindrical with prunts. Rmers are usually green in colour. From as early as the third century AD, skilled glass workers along the Rhine were producing work of great artistic merit. Excavations at Worms, Treves, Cologne, & in the Eifel revealed glass factories that were probably Roman in originindeed, Rmer is German for Roman. Ancient Rhenish graves have yielded gilt-decorated bowls & beakers which were made using the fondo d’oro (base of gold) process in which the design is etched into a layer of gold on the glass surface, & then covered by more glass. These techniques persisted to the fifth century, mythical & biblical themes enjoying great popularity. Out of this era grew that hallmark of German glass, the prunt, a design feature which is still found fifteen centuries later The green glass, forest glass is crafted using traditional methods that have been handed down from one generation to the next in Bohemia (Czech Republic) since the 14th century. Of course, this means that it is hand blown on furnaces demanding great skill. The presence of tiny bubbles in this glass, as well as its pleasant green coloration make it unique & characteristic.
