The heart of the family-owned Ritzenhoff Cristal GmbH still beats where its history began more than 100 years ago: At the company headquarters in Marsberg in the Sauerland region. Using wood from the dense forests of this area, the first glassworks melted quartz sand into glass as early as the 18th century. With roots in the traditional glassmaking craft, the company has developed over the years from a manufactory into one of the most renowned high-tech glassworks in Europe. Today, up to 65 tons of liquid raw glass are processed daily into 140,000 glasses on four parallel glass production lines.
