Dating orrefors glass
The successes of Simon Gate and Edward Hald in Paris in 1925 constituted the start of the long Orrefors tradition of creative design closely combined with genuine and innovative craftsmanship.
Since then, new designers and skilled glassmakers have continued in the spirit of Gate and Hald.
Since the 1980s, designers such as Anne Nilsson, Erika Lagerbielke, Helen Krantz, Matz Borgström, Per B Sundberg, Martti Rytkönen, Lena Bergström, Ingegerd Råman, Malin Lindahl and Efva Attling have helped to propel Orrefors design heritage into the future.
