To attempt copying a visionary silhouette of flowers and leaves arranged in a flower vase on the wall face of the flower vase for composing the flower vase of two layers of an outside semitransparent glass layer and an inside transparent glass layer and specifying the thickness of the outside semitransparent glass layer and the diameter and density of the air bubbles contained and by changing continuously the boundary of both glass layers.

A flower vase consists of two layers, an outside semi-transparent glass layer 1 and an inside transparent layer 2 and the inside light-permeability of flowers arranged is increased by installing a transparent layer in the inside. Further, the outside glass layer 1 is 1-3 times thicker than the inside transparent glass layer 2 and accommodates air bubbles of 1-1,000μm in diameter at 104-108/cm3 in density, as well. Still further, the boundary between the transparent glass layer and the semi- transparent glass layer is continuously changed. Thus, when the inside flowers arranged reflect in the flower vase the received light, their visionary silhouette is copied on the wall plane simultaneously. The following figures are preferable when taking into consideration of light scattering and the like in that the semi-transparent layer 1 is 2-3 times thicker than the transparent layer 2 and in that the diameter of air babbles is 10-1000μm with 10'104-106/cm3 in density.
