A method of providing a tin oxide coating on a moving flat or float glass substrate (16) by chemical vapour deposition by pre-mixing gaseous streams of tin tetrachloride and water at a temperature of between 100 DEG C and 240 DEG C and directing the unitary pre-mixed stream against the glass in substantially laminar flow, the tin tetrachloride and the water only reacting in the region of the surface of the glass to form the tin oxide coating on the glass (16). Alternatively, gaseous streams of anhydrous hydrogen chloride, tin tetrachloride and water may be premixed to form the unitary pre-mixed stream, which pre-mixed stream impacts the glass in substantially laminar flow, the tin tetrachloride and the water reacting with one another in the region of the glass to form tin oxide which forms a coating on the glass. |
