The bottom layer, which is what you see when you look at them from the outside, is some kind of reddish-brown material. This is usually intact, but, unfortunatly it is an insulator. On top of that there was originally a silvery material; in many cases you will find that this seems to be almost completely gone. That was the important electrically conductive part. I think thaOº›¢ lvery stuff suffered from corrosion (oxidation) and some of it got removed each time the window was cleaned on the inside. In the end, there is little or nothing left except for the reddish-brown under layer.
