Abstract
A transparency such as an aircraft front window has an electrically conductive metal, e.g. gold, film vacuum deposited thereon for demisting and/or defrosting purposes. To increase the reliability of such metal film, a layer of an oxide of indium, e.g. indium tin oxide, is formed on the metal film by a sputtering operation to a typical thickness of 10 to 200 nm.
