Abstract
A vitreous system of the invention is provided for use particularly as windowpanes of a car or the like vehicle, and is always kept clean over its whole surface. A multi-layer vitreous body `A` forming the system is composed of an outside glass plate (1), an inside glass plate (2) and a stratified air space (3) defined between the inside and outside plates. A number of jetting orifices (1a) are formed to penetrate the outside plate (1), and a compressor (5) is connected through a piping (4) to the air space (3) so as to charge it with a compressed air, so that this air is blown out through the orifices (1a).
