copper, brass, aluminum, steel. with the application of different substances, a chemical activity is set in motion, changing the metal’s appearance. my “ingredients” might include: salt&water, vinegar, baking soda; products like bleach, muriatic acid or Comet cleanser; to other agents such as sawdust or commercially produced metal surfacers. i keep track of my “recipes” so i have some sense of the ingredient's effects. and yet, numerous factors beyond my control intervene: the metal never begins in the same state; it reacts in different ways or for different reasons to the substances; then, the substances themselves react to each other. for up to a week, I play cook and chemist, watching what happens. in the process, the metal acquires a patina that might include a range of colors and a seemingly infinite variety of patterns and visual textures.
