Vintage frames are easy to come by, but the beautifully aged mirrors to fill them, well, not so much. For Robert Hines of R Squared Antiqued Mirror Co.
in Charleston, South Carolina, the answer is new glass made old. Starting with a sheet of glass, he applies silver nitrate, then distresses it to achieve patinas from lightly aged to heavily distressed. The finished product rivals a period original. Just ask the museum curators and antiques dealers who seek him out. From about $45 a square foot.
