I’ve started making bronze mirrors. The first was cast in one piece and is the same alloy throughout. The second was cast in two pieces, a disk of speculum metal, and a frame. The disk was given a high polish and the frame that holds it was given a patina.
Here are three pictures of the same mirror showing the amazing reflective quality of speculum metal, a bronze alloy. It is 10 inches high by 5 inches wide.
This is the first mirror, a single large piece, 17 inches high by 10 inches wide and weighs about ten pounds! It is currently being exhibited in Santa Fe at the Capitol Art Foundation East Rotunda Gallery.
