Abstract
A layer of silver metal or the like, included as one of a plurality of transparent coating layers upon a glass pane, is protected from staining by providing the pane with a barrier layer comprising the oxides of at least two metals of which one is Me(1) and another is Me(2) wherein Me(1) is titanium, zirconium or hafnium and Me(2) is zinc, tin, indium or bismuth. The barrier layer is non-transmissive of moisture and other staining agents, is amorphous and is free of grain boundaries.
