Product title: Kahler Hammershoi - Large Scandinavian Design Ceramic Vase - White
Product description: This beautifully styled large vase has been produced by one of Denmark's premier brands, Kahler Design. The tall white ceramic vase incorporates a transparent glaze and decorative furrows which are the distinguishing features across all products in the Kahler Hammershoi homeware series. The vase is available in other colors (see variations above) and sizes which complement the rest of the Hammershoi series (search for "Kahler Hammershoi" to see all related products.) To produce the series, Kahler collaborated with Hans-Christian Bauer, a Norwegian-born industrial designer. He reinvented early 20th century ceramist Svend Hammershoi's famous grooved vases into modern vases and practical tableware products. It is Kahler's mission to create accessible art for the people. Now a leading Scandinavian design brand, their roots go back to 1839 as a small Danish pottery producer. For more than 175 years, their tradition has been to collaborate with significant artists to provide distinctive and contemporary collections. Kahler is firmly established as part of Danish cultural heritage, and they strive to preserve history and traditions in each handmade design. Height: 250mm (9.8 In.) Diameter: 200mm (7.9 In.)
