Metal Wall Sculpture(ID: A70003)
The patinas are permanent, and can be hung out of doors. Any shiny brass parts or highlights will slowly tarnish over time like a brass doorknob, but the other colors should change little with age. Most of Bowman's patinas are achieved by applying chemicals in thin solution while heating the metal with an oxy-acetylene torch to catalyze the reaction between chemical and metal, and bring up the color. Many of the colors and effects come from a layering of different patinas.
Bowman's Wallpiece 04.31, like most of his wallpieces, can be hung any direction, on any wall, indoors or out. This piece has a greater contrast of textures than most, from a small piece covered with flowed bronze, to a piece constructed out of small scraps of metal, to the texture of the green mottled patina (upper left in the main picture), which is formed over several days by burying the piece in woodturner's chips saturated with a slow-acting patina.
