Abstract

Electrodes (18) are positioned in intimate contact with an outer surface of a thin electrically-insulating protecting layer (16) of architectural reflective glass (20). Application of a voltage of sufficient magnitude substantially destroys the insulating layer (16) located beneath the electrodes (18). A subsequent application of voltage results in a passage of current through the underlying thin, light-reflective metal or metal oxide layer (14) and in concomitant output of heat.
