Abstract

A process of forming a metal or metal compound coating on a face of a glass substrate which comprises the steps of contacting such face while it is at elevated temperature with a gaseous medium containing a substance in gaseous phase, which undergoes chemical reaction or decomposition to form the metal or metal compound on the face, causing the gaseous medium to flow along the face as a substantially turbulent-free layer along a flow passage which is defined in part by the face of the glass, and drawing residual medium away from the face through exhaust ducting into which the flow passage leads.
