SILICA GEL - is a thirsty, granular compound that offers the best method of preserving the natural beauty of fresh flowers. Silica gel actually absorbs the moisture of the flower with little damage to the flower's color and form. Since ancient times, flowers have been air-dried and sand-dried. These methods, however, produce a shriveled look and faded colors. Now, with Silica Gel, it is possible to preserve nature's beauties. There is no limit to the bouquets you can preserve.
