Bent and/or toughened silver coated glass having light transmission is produced by depositing layers of additional metal over, or both under and over, the silver layer. When the additional metal is used over the silver layer, it is selected from aluminium, titanium, zinc and tantalum. When the additional metal is used both under and over the silver, it is selected from aluminium, titanium, zinc, tantalum and zirconium. The additional metal is used in an amount such that the light transmission of the coated glass increases on bending and/or toughening. The bent and/or toughened coated glass is useful for architectural glazing and as vehicle windows.

Coated glass

Bent and/or toughened silver coated glass having high light transmission is produced by depositing layers of additional metal over, or both under and over, the silver layer. When the additional metal is used over the silver layer, it it selected from aluminium, titanium, zinc and tantalum. When the additional metal is used both under and over the silver, it is selected from aluminium, titanium, zinc, tantalum and zirconium. The additional metal is used in an amount such that the light transmission of the coated glass increases on bending and/or toughening. The bent and/or toughened coated glass is useful for architectural glazing and as vehicle windows.

Method of coating glass

A surface of a hot ribbon of glass, which has just been formed, is coated by directing a flow of coating gas substantially parallel to the glass surface under laminar flow conditions. The laminar flow is in the direction of ribbon advance or co-current to that direction, and the gas is released uniformly across the width of the ribbon. The coating gas contains a constituent, for example a silane, which decomposes on the hot glass surface to deposit a coating, for example silicon, on the glass surface.
