1. A method of making an article, the method comprising:
- providing a first low-iron glass substrate, the first substrate having a thickness of about 0.5-3 mm;
disposing a reflective coating on a major surface of the first substrate;
providing a second glass substrate substantially parallel to the first substrate, the second substrate being oriented over the reflective coating, the second substrate being at least as thick as the first substrate;
laminating together the first substrate with the reflective coating disposed thereon and the second substrate,wherein the reflective article has a reflectivity of at least 90 percent.

Abstract
Certain example embodiments relate to techniques for creating flat laminated mirrors, e.g., for use in concentrating solar power (CSP) applications. In certain example embodiments, the first substrate is a low iron glass substrate, and the second substrate (which may be thicker than the first substrate) is has a higher iron content than the firsts substrate. A reflective coating is provided between the first and second substrates. The first and second substrates are laminated together with the reflective coating between the substrates. In certain example embodiments a reflective article has a reflectivity above 90%, more preferably about 94.5%.

16. A method of making an article, the method comprising:
-
providing a first low-iron glass substrate, the first substrate having a thickness of about 0.5-3 mm; disposing a multi-layer thin-film reflective coating on a major surface of the first substrate, the reflective coating comprising, in order moving away from the substrate, an tin-inclusive layer, an Ag-inclusive layer directly contacting the tin-inclusive layer, and a copper-inclusive layer directly contacting the Ag-inclusive layer; providing a second glass substrate substantially parallel to the first substrate, the second substrate being oriented over the reflective coating, the second substrate being at least as thick as the first substrate, the second substrate having an iron content higher than an iron content of the first substrate; laminating together the first substrate with the reflective coating disposed thereon and the second substrate using a heating profile selected to account for the different heating profiles of the first and second substrates caused by the differing iron contents. - View Dependent Claims (17, 18, 19)

20. A coated article, comprising:
-
a first low-iron glass substrate having a thickness of 0.5-3 mm; a reflective coating comprising a plurality of thin film layers disposed on a major surface of the first substrate; and a second substrate that is substantially parallel to the first high transmission substrate, the second substrate having a higher iron content than the first substrate and being at least twice as thick as the first substrate, wherein the first and second substrates are laminated together with PVB, the PVB hermetically sealing the reflective coating between the first and second substrates, wherein the reflective article has a reflectivity above 90 percent.
