A rare and striking apple-blue Holmegaard “Glug Bottle” (Klukflaske) fitted with a solid sterling silver collar by Gebrüder Kühn, Schwäbisch Gmünd. A luxury cross-border piece combining iconic Danish art glass with high-quality German silverwork. The bottle is hand-blown in deep apple-blue/sea-green, with the characteristic pinched sides that form internal air channels. When the bottle is poured, the trapped air produces the famous “glug–glug” sound, which gave the design its name. The form is closely connected to the classic Holmegaard Klukflaske, one of Denmark’s most iconic glass designs from the late 19th and early 20th century. A well-known glassmaker’s tale says the shape originated by accident when a glassblower got the hiccups, causing the hot glass to collapse inward. Whether myth or truth, the resulting four interior columns became an intentional and highly successful design feature. These channels: give the bottle strength make it easier to hold and create the distinctive glug sound when pouring This bottle shows the same signature Holmegaard construction and colour palette used between ca. 1930–1950.
