Silent Sentinel , N-174 , 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.
