This article describes the conservation and restoration of a 6 ft. 7 in. lead state of William Penn made in England between 1760 and 1770 and attributed to John Bacon the Elder. Prior to restoration, the condition of the Penn statue illustrates well both the historic advantages and disadvantages of working in lead for statuary. New supporting armature elements were constructed of non-corrosive stainless steel. The cavities surrounding the new support rods were filled with a chemically and dimensionally stable water-resistant compound. A polyurethane foam was used. For the exterior, the lead surface will be allowed to form its own patina, controlled by patination oil. The coloration will be a translucent, silvery, charcoal-gray.
