False-colour scanning electron micrograph of etched glass. The textured area surrounding the letter R is the etched surface, which appears frosted to the naked eye. The effect is achieved using a corrosive substance such as hydrofluoric acid, and has applications in the marking of car windscreens allowing identification of stolen vehicles. Magnification: x5 at 35mm size.
