The surface of the bronze <br /> does not appear to have any coating. It appears that the bronze is securely <br /> anchored to the base. <br /> The sculpture is covered with a layer of green and black seemingly stable <br /> corrosion. In general copper and its alloys are relatively resilient materials. The most <br /> common corrosion on copper are o�des, sulfates, sulfites and carbonates. The areas <br /> protected from the driving rain and water runoff appear darker due to the <br /> accumulation of carbon substances and other components of atmospheric particulate <br /> (soot). In those areas black copper sulfides tend to develop. The horizontal surfaces <br /> on the other hand facing upward and at the sides of the sculpture appear somewhat <br /> lighter due to the absence of carbon particles. The alteration of darker (cathodic) <br /> stripes and lighter (anodic) stxipes form the typical zebra pattern that most outdoor <br /> monuments are associated with in heavily polluted urban environments. This <br /> sculpture is relatively evenly corroded green. Some streaking was found on the <br /> face, anns, back, legs and the front of the base. <br /> Stone: <br /> The granite pedestal is in fair condition. Most of the surface of the stone is in <br /> good condition. The stone has been polished and engraved. <br /> A few areas of damage require attention. A relatively large crack {that was <br /> previously repaired with an epoxy resin) was found at the proper front top left <br /> corner of the pedestal. This piece is 7" x 7" x 14". It is very poorly attached and <br /> it appears that it could dislodge. <br />
