This invention relates to glass (1,4) carrying an electroconductive coating (7) and, in particular, to a method of applying bus bars (3,6) on the glass (1,4) to establish electrical contact with the coating (7) and to coated glass (1,4) provided with bus bars (3,6) in accordance with the invention. The method of applying the bus bars (3,6) to the electroconductive coating (7) involves arc spraying molten metal e.g. aluminium on to the coated glass (1,4) in the required configuration which can be defined by either placing a stencil over the surface of the coated glass (1,4) or using adhesive tape (5) to define the required configuration, and then spraying the molten metal. Aluminium has been found to be a most suitable metal for the bus bars and this can be oversprayed with a layer of copper, zinc, tin, a tin alloy, stainless steel, nickel, brass or copper nickel alloy if required. In certain circumstances, for use in architectural applications for e.g. electromagnetic shielding purposes, the bus bars are wrapped around the edge of the glass to provide electrical contact means when the glass is used in a laminate or a double glazing unit. |
