1. A gold mirror on a silica article for reflecting radiation of wavelength between about 550 nm and about 850 nm from the silica articles comprising:

  • a gold layer; and

    a nickel layer forming an adhesion layer between a surface of said silica article and said gold layer;

    wherein said nickel layer is deposited on said surface of said silica article by electroless plating, and said nickel layer has a thickness such that said nickel layer is substantially transparent to infrared radiation, andwherein infrared radiation passes through said silica article and said nickel layer substantially without being absorbed and the infrared radiation is reflected by said gold layer.
