Abstract

A heat-resistant transparent glass article is formed with a film stack deposited on a glass substrate, the film stack comprising one or more infrared reflective films each bearing on its surface facing away from the substrate a protective film of niobium metal having a thickness of up to 25 .ANG. and preferably in the range of about 7 .ANG. to 20 .ANG.. A protective film of niobium metal or metal oxide may be formed on the other surface (facing the substrate) of each infrared reflective film. Metal nitride films such as silicon nitride may be employed between neighboring infrared reflective films, and as an outer protective film.
