1. A process for forming a high reflectivity, adherent, corrosion-resistant gold-containing layered structure on a quartz base, comprisingvacuum depositing a first, relatively thin layer of gold chromium alloy on the quartz;

  • vacuum depositing on the first layer a second, relatively thick outer layer consisting essentially of gold for providing high infrared radiation reflectivity to the quartz;

    forming a third layer on the second, gold layer the third layer being of polymer material selected from silicone resin and polyimide; and

    heating the resulting layered structure to enhance the adhesion of the gold layer via the gold chromium layer to the quartz and to cure the polymer.
