A 19th-century porcelain marvel that only reveals its hidden image when backlit

In short: A lithophane is a thin, translucent plaque that appears as a nondescript slab until light shines through it from behind. By varying the thickness of the material, artists create intricate, ghost-like images in shades of grey. Once a Victorian sensation, this delicate art form is now undergoing a digital revival.

Invented in France in the 1820s by diplomat Baron Paul de Bourgoing, the lithophane—from the Greek for 'stone' and 'to appear'—was designed to transform light into art. The process involved carving a wax plaque on glass, casting it in plaster of Paris, and firing the resulting porcelain. Because the material was often as thin as 1/8 inch, the firing process was notoriously difficult, with wastage rates reaching as high as 60 percent. While early examples were marked 'AdT' to protect the diplomat's reputation, the technique quickly spread across Europe, with Germany’s Königliche Porzellan-Manufaktur in Berlin becoming the dominant producer during the 19th century.

The peak of production occurred between 1840 and 1870, with subjects ranging from religious scenes and landscapes to sentimental domestic portraits. Although the technique produced images in grisaille, some were later hand-painted with translucent watercolors. While Chinese porcelain featured a similar 'hidden decoration' technique known as an hua, it was typically used for floral patterns on closed vessels rather than backlit images, marking the European lithophane as a distinct artistic tradition. By the end of the 19th century, the fashion had largely faded, though it saw a brief resurgence for the 1902 coronation of Edward VII.

In recent decades, the lithophane has been reborn through modern technology. While studio potters still work with porcelain, the medium has expanded to include glass, plastic, and 3D-printed materials. The transition to digital fabrication began in earnest around 2011, with artists like Jonty Hurwitz pioneering 3D-printed versions. The process was further democratized in 2015 when developer Mark Durbin launched 3dp.rocks, a tool that allows users to convert images into 3D meshes for printing. Today, consumers use fused deposition modeling or stereolithography to create high-fidelity gradients that rival the appearance of 19th-century originals, proving that this Victorian curiosity remains a compelling intersection of light, shadow, and material science.
