Sleep Tight , N-79 , Our most popular Lithophane product is the plug-in night-light. First invented in France in 1827, a Lithophane is a porcelain engraving that virtually comes alive when illuminated from behind! A panel of different thickness of translucent, kiln-fired porcelain creates the image. A breathtakingly detailed picture in warm sepia tones emerges when lit. These illuminated artworks are so detailed; they will amaze you for years to come. Our Night Lights are the perfect gift, reasonably priced and nicely gift boxed,including history and care literature. Approx. size 3.5 inches x 4.5 inches. The curved design is pictured below. Some styles are also available in color. The flat panels are interchangeable with any of the flat panel designs so you can change them easily.
