Magic lantern slides are early, hand painted or photographic glass images that could be projected by a specialized lantern using candles, oil or electric light to display images onto walls, acting as a 17th-to-20th-century predecessor to cinemas and slide projectors. Originally some pictures were hand painted on glass slides. Initially, figures were rendered with black paint but soon transparent colors were also used. Sometimes the painting was done on oiled paper. Usually black paint was used as a background to block superfluous light, so the figures could be projected without distracting borders or frames. Many slides were finished with a layer of transparent lacquer, but in a later period cover glasses were also used to protect the painted layer. After 1820 the manufacturing of hand colored printed slides started, often making use of decalcomania transfers. Many manufactured slides were produced on strips of glass with several pictures on them and rimmed with a strip of glued paper. Many rare photographic images are discovered on magic lantern glass slides
