摘要

A process of coating glass with tin oxide by exposing the glass to a gaseous medium containing tin tetrachloride vapor 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 2.5x10-3 atm. and contains water vapor in a concentration corresponding to a partial pressure of at least 10x10-3 atm. and the gaseous medium contacts the glass face to be coated while said medium is at a temperature of at least 300 DEG C. and such face is at a temperature above 550 DEG C.
