The metal surface is “painted” using layer upon layers of different substances. This process sets in motion an evolving “alchemy” of chemical activity, as I work and rework the metal. The patinas that result can include vibrate colors, such as orange or blue, or can be subtle: ghosts of previous marks are revealed as the patina is sanded back to bare metal. There is no guarantee on the outcome, too many factors are always in play, which adds to the mystery of this exciting, uncontrollable process. My choice of “substances” include kitchen staples like salt, vinegar, and baking soda, to cleaning products like bleach, or other agents such as sawdust, muriatic acid, and commercially produced metal patinas.
