A B S T R A C T The invention concerns a process of coating glass with tin oxide by exposing the glass to a gaseous medium containing tin tetrachloride vapour under conditions causing formation of the oxide coating by chemical reaction and/or decomposition. The glass is moved continuously through the coating zone and in order to promote a high optical quality of the coating the gaseous medium is formed with a tin tetrachloride concentration corresponding to a partial pressure of at least 2.5 x 10 3-atm. and contains water vapour in a concentration corresponding to a partial pressure of at least 10 x 10-3 atm. and the gaseous medium contacts the glass face to be coated while said medium is at a temperature of at least 300°C and such face is at a temperature above 550°C.
