Light reflectors were placed under Christmas tree light bulbs, allowing their glittered and foiled papers to reflect the colored light. Glittered reflectors used glass and mica shavings to reflect the light. These colored foil reflectors were made in Germany. With the introduction of electric tree lights, some ornaments were made specifically to catch the light or spin above the heat generated by the bulbs. Light bulbs themselves even featured various shapes and designs. “Whirl-Glo” paper shades were placed over tree lights, causing them to spin. Gift of Maureen Creager, 85.11.160
