Compositions in a transparent vase are built not only over the vase, but also in the vase itself and even in the water. Sometimes the plants are placed entirely in a vessel, without taking them outside of it. In a transparent vase you can see its contents, which is usually undesirable, but it can also become its advantage, for example, when creating interesting and original arrangements in which the transparency of the glass plays an active role. Very often, inside an opaque vessel, beautiful bases of plants, their combinations, intersections, which could complement the beauty of the arrangement above the vase, are hidden from the eyes of the observer.
When the composition is created in a conventional ceramic vase, the plant to vase ratio is about 7/3; however, if the dishes are glass, this ratio changes in favor of the vessel, since it acquires a dominant role, and when placing flowers, one should try to emphasize its merits.
Placed in a glass vase, the composition seems airy, it seems as if it is floating in the air.
The beauty of some flowers, for example, sweet peas, gerbera, freesia, cyclamen, is favorably emphasized in glass vases. Some ikebana masters specifically use glassware to arrange original compositions with flowers or leaves trimmed under water.
The arrangement looks beautiful, rich and unusual, where, for example, several gerberas rise above the vase, and in the water, as their reflection, 1-2 flowers of the same plants are visible. You can also place a dracaena stem bent along the wall of the vessel into the water, part of which is exposed from a vase, add some flowers, for example, a lily. It so happens that it is enough to throw 1-2 lemons into a vessel and add a flower to them to get a completely finished attractive composition.
In a transparent vase, the usual fastening for branches and pedicels is not suitable, since auxiliary supports cannot be used. We have to look for other ways. The best, of course, is a stable weave of decorative material in water. As a last resort, you can also use a tattoo, wrapping it in thin white paper or covering it with sand or pebbles.
It should be borne in mind that tattoos and plants appear larger in water than they really are. Water gives us an additional effect of radiance and refraction of rays, and the curvature and bends of the glass sometimes unexpectedly reveal some parts of the plants, even in a completely undesirable form for us.
The play of light, the direction from which it falls on the vase (from below, from the side, from behind) is also of great importance. You can admire for a long time the changes taking place in a glass vase under different lighting of the day, evening, night. When plants stand for some time in water in the light, transparent bubbles appear on them, this is also very beautiful.
The effect of water is greatly increased if the water does not completely fill the vessel, but only half or three quarters of its height.
The transparency of the glassware obliges the arranger to take very serious care of the neatness and beauty of the stems and flowers immersed in water, about the constant freshness and purity of water and glass.
Transparent and opaque colored glass vessels are very beautiful. Interesting compositions in 2-3 vases, dipped into one another.
