Heated laminated window and method of assembling same

A transparent electroconductive window comprising a non-electroconductive assembly element of transparent material selected from the group consisting of glass, polycarbonates, acrylic esters, polyesters, polyvinyl acetals and polyurethanes, an electroconductive circuit portion selected from the group of transparent electroconductive coatings, lines of electroconductive material and electroconductive wire carried by said element, and a self-soldering bus substantially all metallic bar consisting essentially of a mixture of finely divided particles of a highly conductive metal selected from the group consisting of silver, gold, platinum, copper and aluminum and high melting point electroconductive alloys within an electroconductive metal alloy having a fusion point between about 70.degree. C. and about 150.degree. C., said mixture consisting essentially of 85-97 parts by weight of particles of said metal and 15-3 parts by weight of said metal alloy.
