All colored glass is stained glass. The art medium of the windows of the Church of St. Paul in the Desert are more particularly known as faceted glass. This is probably the oldest form of the use of stained glass in windows. The glass was colored by throwing in metals and metallic oxides.
Metallic gold produces pink.
The background in each window, thereby, becomes opaque, bringing the color and beauty of each piece of glass more into prominence. The windows weigh about eight pounds per square foot, and the maximum size that can be used is nine square feet. The medium is one of strength and massiveness, not daintiness and over subtlety.
