photosensitive glass [¦fōd·ō′sen·səd·iv ′glas]
(graphic arts) Glass containing submicroscopic metallic particles; when ultraviolet light passes through a negative on the glass, it precipitates the particles, with shadowed areas of the negative permitting deeper penetration into the glass than highlight areas, giving the picture three dimensions and color; photograph is developed by heating the glass to 1000°F (538°C).
