Engraving
Engraving is the practice of incising a design on to a hard, usually flat surface, by cutting grooves into it. The result may be a decorated object in itself, as when silver, gold, steel, or glass are engraved, or may provide an intaglio printing plate, of copper or another metal, for printing...

s that are "flat". The images change characteristics depending on the light source behind them. Window lithophane panel scenes change throughout the day depending upon the amount of sunlight. The varying lightsource is what makes lithophanes more interesting to the viewer than two dimensional pictures.

The word "lithophane" derives from Greek "litho", which is from "lithos" which means stone or rock, and "phainein" meaning "to cause to appear" or "to cause to appear suddenly". From this is derived a meaning for lithophane of "light in stone" or to "appear in stone" as the three dimensional image appears suddendly when lit with a back light source.

European lithophanes were first produced nearly at the same time in France, Germany, Prussia, and England around the later part of the 1820s. Many times historians credit Baron Paul de Bourging (1791–1864) with inventing the process "email ombrant" (pottery decorating) of lithophanes in 1827 in France. Robert Griffith Jones acquired Bourging's rights in 1828 and licensed out to English factories to make them. The English factories sometimes used the name "lithophane" for specimens of ordinary "email ombrant." Some say however it was Georg Friedrich Christoph (1781–1848) of Prussia that actually perfected the true lithophane process in 1828. Others say the technique was developed in Berlin and other parts of Germany by such manufacturers as Königlichen Porzellan-Manufaktur and Porzellanmanufactur. This is why sometimes lithophanes are referred to as "Berlin transparency." There is a well known mark of Ad'T' on lithophanes from Rubles, near Melun

 the Chinese produced bowls "as thin as paper" with secret decorations in them. According to W.

. Qingbal wares had their translucency with carved and molded designs of flowers, fish, and birds. Japanese lithophane tea sets are referred to as Dragonware and were popular for GI trading in Japan during World War II.

In the early part of the 20th century many lithophane investigators were making connections between the European 18th and 19th century ceramics and the Chinese porcelains. In France they used the term "Blanc de Chine" in the 18th century to designate a highly translucent Chinese porcelain. Porcelain factories in France, Germany and England mimicked the Chinese "Blanc de Chine" in the seventeenth and eighteen centuries. These same factories then started to make lithophanes in the early part of the 19th century. The technical and aesthetic inspirations for European lithophanes can be seen coming from Chinese works, however the exact relationship between the two remains elusive to this day. The missing link is a definite known lithophane plaque produced anywhere in China prior to 1800.

Lithophanes were made by specialized European craftspeople beginning as an image carved in warm wax on a glass plate. This was then backlit and carved. Sometimes the carving table was near a window and had a mirror below the table to provide constant light for carving. A modeler would duplicate the image on a flat wax plate carving relief and intaglio. Where the wax was carved thinnest more would shine through. Of course where the wax was carved thickest then there was less light shone through.

. It turned out that up to about 60% of the porcelains would warp or crack in the kiln causing them to become useless. Finished lithophanes are somewhere between one sixteenth of an inch thin to almost a quarter inch (1.5 to 6mm) thick.

Lithophanes were produced in Austria, Belgium, Bohemia, Czechoslovakia, Denmark, England, France, Germany, Ireland, Italy, Norway, Portugal, Russia, Sweden, and Wales in the 19th century. Lithophanes by the hundreds of thousands were made in the middle of the eighteen hundreds by such firms as Wedgwood in England, Meissen in Dresden, and Belleek in Ireland. Lithophanes were produced then in the United States as well, however not nearly as much as in Europe. Popular subjects of lithophanes were religious themes, portraits, genre scenes, literature ideas such as stories from the Bible, and masterpieces. Some lithophanes even commemorated events such as the opening of the Eiffel Tower in 1889.
Lithophanes were in various formats from plaques to be hung in windows to candle shields. They were also in fireplace screens, night lights, tea warmers, and match boxes. Many were pieces of bottoms of beer steins, mugs and cups. Some were souvenir ornaments of erotica images. They were even in lanterns and lamps. Rare miniature lithophanes are parts of doll house furnishings.

Colt probably got the idea from the 1851 Great (Crystal Palace) Exhibition in London or the New York Great Exhibition of 1853 or in a Prussia visit in 1854. Scenic views and portraits were for the public and private rooms of Colt's wife. Inspirational panes were for the windows of Colt's upstairs bedroom.

In this lithophane portrait he is sitting at a small desk holding a "Belt Pistol" in his right hand and has a directional compass in his left hand. One of these he sent to Senator Thomas J.
