Floating flowers
No, they are not "doughnuts" - but they look similar. The glass ring with the hole in the middle floats on the water and the last flower from your bouquet has a new home. Pretty wonderful in large bowls in combination with the Float (Art. 854), Bubbles (Art. 859 and Art 859.1) and the Swimming Frogs (Art. 853).
Production method:
Glass tubes and glass rods blown and shaped at the burner- so-called "lamp technique”.
