The sunset scene is a leaded glass panel with a white wooden frame. The river suggests the movement of the water because of the transparent properties of the glass and the different types of glass used. The mountains are cast in shadow on the front side by the use of several layers of glass plates attached on the back side. This technique was developed by Tiffany Studios and is known as mottling. That technique is used throughout to create shadow and depth, both under the tree and among the plants where the mottled glass really adds the illusion of sunlight. Many of the techniques used for making these types of windows include many layers and colors to depict a different motion, or to complete and enhance the fullness of the view intended for the piece.[4]
