The SCHOTT production site in Grünenplan, Germany, serves as the global competence centre for manufacturing thin and ultra-thin glass.

The Home of the Thinnest Glass in the World
A variety of glass types and optical materials are produced in Grünenplan using the down-draw production process. This method enables the production of ultra-thin glass, SCHOTT UTG®, which, at just 25 microns thick, is finer than a human hair. The site spans 115,500 m² across three locations—two in Grünenplan itself and a third in the neighbouring town of Eschershausen, approximately 10 km away.

About the Region

A History of Glassmaking
Grünenplan, known as "the glassmakers' village", was founded in 1747 during the expansion of a workers’ settlement for a former mirror glass factory. Today, the town, located in southern Lower Saxony between Hanover and Göttingen, offers over 150 kilometres of hiking trails and is a popular destination for outdoor activities.
