Abstract: A process for manufacturing mirrors with increased reflectance includes forming a silver layer on a surface of a glass substrate, during which the surface is contacted with a silvering solution, and painting at least one paint layer to cover the silver layer. Between forming the silver layer and the painting, the process includes reheating the silver layer to a temperature of at least 200° C.

Abstract: The invention relates to a mirror including a glass substrate covered with a silver layer, which is in turn covered with at least one paint layer, wherein the intensity ratio of the crystallographic orientations (111)/(200) within the silver layer is less than 5.0. Said mirror is characterized in that the silver layer has a correlation length (CLz) (111), as measured by X-ray diffraction using the Scherrer method (i.e., using the Scherrer equation) of greater than 27.0 nm.
