There's another realm of course where the environment forever remains primeval and pure, in the realm of fairy tales.Denmark is known as the kingdom of fairy tales. That fairy-dreamland quality is apparent in the art of the country's glass makers. A glass exhibition is open at the Guangdong Art Gallery. To the viewer the exhibits are a visual delight and an intriguing insight into a world of imagination.Thirty-seven pieces are on display. Each is the only one of its kind. Each is designed and manufactured by a Danish artist. The works demand the highest order of the glassmaker's art, But organizers hasten to point out, not only is this a display of craftsmanship, the exhibition also reveals the inner child that lives in the adult artists.
