Abstract
A method of producing a heated mirror by selective removal of conductive reflective material from an insulating substrate to define a conductive path with a predetermined resistance. The conductive reflective material can be removed by scoring down to the substrate or by scoring and etching. Conductive paths are defined by tracks in a serpentine, spiral or interleaved comb pattern. Isolated regions may be left to designate a Trade Name which is visible when the mirror is demisted. Different insulating backings and terminals are also described.
