<p>A method of treating flat glass to reduce its vulnerability to scratching, e.g. during storage and/or transit, wherein a transparent film of a cationic surface active agent is adsorbed on the glass by applying an aqueous solution of the surface active agent to the glass on the production line and drying the glass. The solution may be applied to the glass after is has been washed, near the end of the production line, using for example an anionic surface active agent as detergent. Alternatively, a solution containing both a cationic surface active agent and an nonionic surface active agent as detergent may be applied to the glass to wash it, followed by rinsing with water and drying.</p> |
