During the late 1940s and early 50s, fiberglass was being molded into furniture and pressed paper thin for lampshades. It was generally wrapped around metal frames and held in place with lacing. The fiberglass was most often left white, but it was not unusual to see it in tan, off-white, pink, turquoise and pale green. The surface was often decorated with popular motifs such as leaves, atomic shapes, stars and abstract designs, usually in gold or black.
In the 1950s science was influenceing every facet of life. Household objects began to take on space age characteristics. Thickly molded fiberglass, similar to that used in furniture, was molded into cones and used as shades. Flat shades covered some, echoing the shape of a flying saucer. Metal arms held the shades at odd angles. The fiberglass could be pressed flat or left "furry" for texture.
During the 1960s plastic shades began to replace fiberglass, which was more widely used for insulation. Many of the old shades are still with us, however, because fiberglass does not break down or wear out easily.
