Parrot and Waterfall. This piece graces the entry of Uroboros Glass Company, Portland, Oregon. The stained glass used for the waterfall is made of drapery glass, which is a form of stained glass that is heavily rippled and looks like cascading water. That glass was soldered over the glass used for the water in the stream. Careful selection in the cutting of the stained glass makes the lights and shadows of leaves, flowers and feathers come alive.
